1 00:00:00,000 --> 00:00:05,000 So guys, finally, I'm excited to implement this amazing end to end project related to text summarization. 2 00:00:05,000 --> 00:00:08,000 So I will take the same folder inside this. 3 00:00:08,000 --> 00:00:11,000 I will go ahead and create a API key. 4 00:00:11,000 --> 00:00:14,000 So let me just go ahead and create this. 5 00:00:14,000 --> 00:00:16,000 Sorry not API app.py file. 6 00:00:16,000 --> 00:00:17,000 Okay. 7 00:00:17,000 --> 00:00:20,000 And this is where I'm actually going to write the entire coding. 8 00:00:20,000 --> 00:00:23,000 See the reason why I am creating this kind of folder structure. 9 00:00:23,000 --> 00:00:28,000 You know, because you understand like how every project is basically getting created. 10 00:00:28,000 --> 00:00:35,000 And I'm just putting all the common libraries that may, we may be using in creating an end to end projects. 11 00:00:35,000 --> 00:00:36,000 Right. 12 00:00:36,000 --> 00:00:38,000 And that will be all at one place. 13 00:00:38,000 --> 00:00:42,000 So that is the reason, uh, I'm basically creating all the projects in this same way. 14 00:00:42,000 --> 00:00:43,000 Okay. 15 00:00:43,000 --> 00:00:46,000 So now, uh, let's go ahead and start our coding over here. 16 00:00:46,000 --> 00:00:52,000 So first of all, what we are going to do is that, uh, here we are also going to use some new libraries. 17 00:00:52,000 --> 00:00:52,000 Okay. 18 00:00:52,000 --> 00:00:56,000 So first of all, the library that I really want to use is something called as validators. 19 00:00:56,000 --> 00:00:59,000 Now what exactly is this validator. 20 00:00:59,000 --> 00:01:06,000 Since we are going to use or work with Earl over here, this validator basically is an inbuilt library 21 00:01:06,000 --> 00:01:12,000 which is not an inbuilt library, but it is an external library which actually helps you to validate 22 00:01:12,000 --> 00:01:12,000 the URL. 23 00:01:12,000 --> 00:01:13,000 Okay. 24 00:01:13,000 --> 00:01:19,000 So I will be using one of this particular, uh, version that is 0.281.1. 25 00:01:19,000 --> 00:01:21,000 I think this is the recent version that is going on. 26 00:01:21,000 --> 00:01:26,000 Along with this, I will also be using YouTube transcript. 27 00:01:26,000 --> 00:01:29,000 Transcript underscore API. 28 00:01:29,000 --> 00:01:36,000 Now, with the help of this, whenever we give any YouTube URL okay, we will be able to read the entire 29 00:01:36,000 --> 00:01:38,000 transcript for that particular video. 30 00:01:38,000 --> 00:01:38,000 Okay. 31 00:01:38,000 --> 00:01:42,000 So this is another one library that we are basically going to use. 32 00:01:42,000 --> 00:01:47,000 Uh, let's see whether when we are doing the coding like any more libraries will be required or not. 33 00:01:47,000 --> 00:01:50,000 So now I will go over here, I will open my command prompt. 34 00:01:50,000 --> 00:01:55,000 First of all, I will go ahead and make sure that I do the installation of the requirement dot txt. 35 00:01:55,000 --> 00:02:00,000 So first thing that you really need to validate is that are we in our environment right. 36 00:02:00,000 --> 00:02:01,000 That is V and V. 37 00:02:01,000 --> 00:02:03,000 Yes it shows over here. 38 00:02:03,000 --> 00:02:07,000 We will go ahead and write pip install minus r requirement dot txt. 39 00:02:07,000 --> 00:02:11,000 So once I go ahead and execute it here you can see remaining all the libraries. 40 00:02:11,000 --> 00:02:13,000 It shows requirement already satisfied. 41 00:02:13,000 --> 00:02:17,000 But now YouTube YouTube transcript underscore API validators. 42 00:02:17,000 --> 00:02:19,000 You can see it has got successfully installed. 43 00:02:19,000 --> 00:02:24,000 So now let me just go ahead and close this and let me start writing my code. 44 00:02:24,000 --> 00:02:29,000 Uh, the first thing first, what I really need to do is that I have to import this validators. 45 00:02:29,000 --> 00:02:32,000 So I'll go ahead and write import validators. 46 00:02:33,000 --> 00:02:37,000 And then I'm going to also import Streamlit as st. 47 00:02:38,000 --> 00:02:39,000 Okay. 48 00:02:39,000 --> 00:02:46,000 Uh I'm going to use this then uh from lang chain dot prompts. 49 00:02:46,000 --> 00:02:51,000 Okay I'm going to import my prompt template which I'm going to specifically use. 50 00:02:51,000 --> 00:02:52,000 Okay. 51 00:02:52,000 --> 00:03:00,000 Then uh again from lang chain underscore grok, we are going to import chat grok, which I'm actually 52 00:03:00,000 --> 00:03:03,000 going to use to communicate with my LLM models. 53 00:03:03,000 --> 00:03:08,000 Then from lang chin dot chains dot summarize. 54 00:03:08,000 --> 00:03:13,000 Because we are going to use the summarize for using any of the summarize techniques that we have already 55 00:03:13,000 --> 00:03:14,000 learned. 56 00:03:14,000 --> 00:03:18,000 So here we will be importing this load summarize chain. 57 00:03:18,000 --> 00:03:19,000 Then again uh. 58 00:03:19,000 --> 00:03:27,000 Uh, one more library that I am going to specifically use with respect to YouTube and uh, any other 59 00:03:27,000 --> 00:03:27,000 websites. 60 00:03:27,000 --> 00:03:27,000 Right. 61 00:03:27,000 --> 00:03:30,000 We also require some kind of document loaders. 62 00:03:30,000 --> 00:03:34,000 So if you remember in the initial stages we discussed about document loaders. 63 00:03:34,000 --> 00:03:34,000 Right. 64 00:03:34,000 --> 00:03:41,000 So Langston underscore community dot document loaders I'm going to import one is YouTube loader. 65 00:03:41,000 --> 00:03:44,000 So for this I will be using this YouTube loader. 66 00:03:44,000 --> 00:03:47,000 You can also take the audio if you are really interested. 67 00:03:47,000 --> 00:03:48,000 Okay. 68 00:03:48,000 --> 00:03:58,000 And then we will also go ahead and take a unstructured and structured or unstructured URL road. 69 00:03:58,000 --> 00:03:58,000 Right. 70 00:03:58,000 --> 00:04:04,000 And there are so many like see unstructured HTML is there, CSV is there, email is there, pub is there. 71 00:04:04,000 --> 00:04:07,000 But here we are just going to use a URL. 72 00:04:07,000 --> 00:04:07,000 Let's see. 73 00:04:08,000 --> 00:04:11,000 We'll go ahead and write unstructured URL road. 74 00:04:11,000 --> 00:04:12,000 Okay. 75 00:04:12,000 --> 00:04:16,000 That basically means directly from the URL we will be able to load the content here. 76 00:04:16,000 --> 00:04:17,000 You can also use CSV. 77 00:04:17,000 --> 00:04:21,000 You can also use any other things like let's say you want to upload go ahead and upload CSV. 78 00:04:21,000 --> 00:04:25,000 You can also do that okay as I said guys it is vast. 79 00:04:25,000 --> 00:04:26,000 Lang chain is really really vast. 80 00:04:26,000 --> 00:04:27,000 Okay. 81 00:04:27,000 --> 00:04:29,000 So finally let's go ahead and create our Streamlit app. 82 00:04:29,000 --> 00:04:31,000 Now initially to create the Streamlit app. 83 00:04:31,000 --> 00:04:38,000 What I will do I will go ahead and set up my page config and uh h3 dot title next dot subheader. 84 00:04:38,000 --> 00:04:47,000 Okay, um, then I will quickly go ahead and get the grok API key that I really want to use. 85 00:04:48,000 --> 00:04:56,000 Uh, and I will also create an URL field, the URL field to uh, which URL we really need to summarize, 86 00:04:56,000 --> 00:04:56,000 right. 87 00:04:56,000 --> 00:04:58,000 To be summarized, I will right over here. 88 00:04:59,000 --> 00:05:00,000 Okay. 89 00:05:00,000 --> 00:05:03,000 Um, and, uh, the Earl field. 90 00:05:03,000 --> 00:05:05,000 I'll not say Earl to be summarized. 91 00:05:05,000 --> 00:05:06,000 Whatever. 92 00:05:06,000 --> 00:05:09,000 Earl, we really want to summarize, it can be. 93 00:05:09,000 --> 00:05:13,000 I'll write over here as it can be white or website. 94 00:05:13,000 --> 00:05:13,000 Okay. 95 00:05:13,000 --> 00:05:21,000 So once this is done, then I will go ahead and write with s t dot s sidebar. 96 00:05:22,000 --> 00:05:22,000 Okay. 97 00:05:22,000 --> 00:05:26,000 And here I will go ahead and create the sidebar itself. 98 00:05:26,000 --> 00:05:31,000 Here I will go ahead and first of all get my API key right. 99 00:05:31,000 --> 00:05:34,000 So for this I will go ahead and write TX dot text input. 100 00:05:34,000 --> 00:05:41,000 So I'm just creating a field on the sidebar like text input where I will be giving my grok API key. 101 00:05:41,000 --> 00:05:46,000 So let me just go ahead and write grok grok API key. 102 00:05:47,000 --> 00:05:47,000 Okay. 103 00:05:47,000 --> 00:05:52,000 And here we are basically going to take the value as blank right. 104 00:05:52,000 --> 00:05:56,000 Initially it will be and type will be password. 105 00:05:56,000 --> 00:05:56,000 Okay. 106 00:05:56,000 --> 00:05:57,000 Perfect. 107 00:05:57,000 --> 00:05:58,000 Till here we have done it. 108 00:05:58,000 --> 00:06:00,000 Then let's go ahead and create our URL. 109 00:06:00,000 --> 00:06:04,000 It'll be nothing but PT dot text underscore input. 110 00:06:04,000 --> 00:06:08,000 And here I'm going to basically give my URL. 111 00:06:09,000 --> 00:06:09,000 Okay. 112 00:06:09,000 --> 00:06:13,000 And over here I will keep my initial label. 113 00:06:13,000 --> 00:06:15,000 Visibility is equal to false or collapsed. 114 00:06:16,000 --> 00:06:16,000 Okay. 115 00:06:16,000 --> 00:06:21,000 The reason over here why I'm writing it as collapsed because it should not be highlighted unless until 116 00:06:21,000 --> 00:06:22,000 we go ahead and click it. 117 00:06:22,000 --> 00:06:24,000 Okay, so this will be collapsed. 118 00:06:25,000 --> 00:06:26,000 Uh, this is perfect. 119 00:06:26,000 --> 00:06:26,000 Till here. 120 00:06:26,000 --> 00:06:28,000 We have done this. 121 00:06:28,000 --> 00:06:28,000 Okay. 122 00:06:29,000 --> 00:06:33,000 Um, next, uh, what I will do, I'll go ahead and create my button. 123 00:06:33,000 --> 00:06:33,000 Okay. 124 00:06:33,000 --> 00:06:42,000 So for that, I will go ahead and write if s t dot button, I will go ahead and create my summarize 125 00:06:43,000 --> 00:06:49,000 the content from y t or website. 126 00:06:49,000 --> 00:06:50,000 Okay. 127 00:06:50,000 --> 00:06:52,000 So this will basically have the information in the button. 128 00:06:52,000 --> 00:06:53,000 Okay. 129 00:06:53,000 --> 00:07:00,000 Uh now let's go ahead and first of all validate all the inputs Right. 130 00:07:00,000 --> 00:07:02,000 So we're validating I will go ahead and write. 131 00:07:02,000 --> 00:07:03,000 If not okay. 132 00:07:04,000 --> 00:07:05,000 Grok API key. 133 00:07:05,000 --> 00:07:09,000 If the grok API key is not given okay I will also do a tag dot strip. 134 00:07:09,000 --> 00:07:14,000 Or I'll also go ahead and check for not URL dot strip. 135 00:07:14,000 --> 00:07:18,000 So we will also put a condition with respect to the URL. 136 00:07:18,000 --> 00:07:24,000 I'll say that hey, if the URL is not given okay, dot strip strip basically means removes the empty 137 00:07:24,000 --> 00:07:25,000 characters. 138 00:07:25,000 --> 00:07:30,000 I will just go ahead and give an error saying that SD dot error and I'll guide. 139 00:07:30,000 --> 00:07:35,000 Please provide the information. 140 00:07:36,000 --> 00:07:41,000 Please provide the information okay a generic information like that right. 141 00:07:41,000 --> 00:07:47,000 Otherwise I'll also give an else if condition where I'll say whether my URL that I've actually given 142 00:07:47,000 --> 00:07:49,000 uh we need to validate also that. 143 00:07:49,000 --> 00:07:49,000 Right. 144 00:07:49,000 --> 00:07:55,000 So here I will say if not validators dot URL. 145 00:07:55,000 --> 00:07:58,000 And here I'm going to basically go ahead and give my URL. 146 00:07:58,000 --> 00:08:02,000 So this URL can be your website URL. 147 00:08:02,000 --> 00:08:03,000 It can be a YouTube URL. 148 00:08:03,000 --> 00:08:07,000 So I'll go ahead and just write a generic URL over here. 149 00:08:07,000 --> 00:08:10,000 And here will be my API key. 150 00:08:10,000 --> 00:08:13,000 Here will be my generic URL itself. 151 00:08:13,000 --> 00:08:13,000 Right? 152 00:08:13,000 --> 00:08:16,000 So all this information is over here. 153 00:08:16,000 --> 00:08:18,000 I will also go ahead and make this particular check okay. 154 00:08:18,000 --> 00:08:24,000 So I'll say hey please provide the information to get started okay. 155 00:08:24,000 --> 00:08:26,000 Something like this some errors. 156 00:08:26,000 --> 00:08:28,000 We will try to put it over here. 157 00:08:28,000 --> 00:08:31,000 So now we are checking whether this URL URL is a validator. 158 00:08:31,000 --> 00:08:33,000 You validating your URL or not. 159 00:08:33,000 --> 00:08:34,000 It is a valid URL or not. 160 00:08:34,000 --> 00:08:35,000 So here. 161 00:08:35,000 --> 00:08:38,000 If it is not a valid URL, I will just go ahead and write SD dot error. 162 00:08:38,000 --> 00:08:45,000 Please enter a valid URL okay. 163 00:08:45,000 --> 00:08:47,000 And here I will also go ahead and write. 164 00:08:47,000 --> 00:08:52,000 It can maybe a just go ahead and write this error message. 165 00:08:52,000 --> 00:09:00,000 It can maybe a witty video URL or website URL. 166 00:09:01,000 --> 00:09:05,000 Okay so I'm giving some validation also so that you'll be able to check it out. 167 00:09:05,000 --> 00:09:11,000 Then finally in the else block, uh, what I will do is that if all these conditions are satisfied and 168 00:09:11,000 --> 00:09:16,000 this is where we have to start our coding and whatever happens in the back end. 169 00:09:16,000 --> 00:09:19,000 So I'll say, hey, go ahead and create a try block okay. 170 00:09:19,000 --> 00:09:22,000 And we will also handle the exception with respect to this. 171 00:09:22,000 --> 00:09:27,000 And I'll say hey width width street dot spinner. 172 00:09:27,000 --> 00:09:28,000 Okay. 173 00:09:28,000 --> 00:09:31,000 And I'll say waiting. 174 00:09:31,000 --> 00:09:32,000 Okay. 175 00:09:32,000 --> 00:09:35,000 Waiting till this entire information is basically coming up. 176 00:09:35,000 --> 00:09:41,000 You know, we will first of all load the we will load the URL itself right. 177 00:09:41,000 --> 00:09:42,000 URL data. 178 00:09:42,000 --> 00:09:48,000 So the first step over here is that loading the uh website data okay. 179 00:09:48,000 --> 00:09:55,000 Website or YouTube video data or y t video data. 180 00:09:55,000 --> 00:09:58,000 Okay, so once this is done, we go to the next step. 181 00:09:58,000 --> 00:10:04,000 I'll give a condition in my URL whether youtube.com is present or not. 182 00:10:04,000 --> 00:10:11,000 So if youtube.com is present in this generic URL, then what I'm actually going to do, I'm going to 183 00:10:11,000 --> 00:10:12,000 create a loader. 184 00:10:12,000 --> 00:10:16,000 And inside this I will be using this YouTube loader which I have actually initialized. 185 00:10:16,000 --> 00:10:18,000 As soon as we use the YouTube loader. 186 00:10:18,000 --> 00:10:27,000 All uh, there is an inbuilt function over here, like from YouTube URL where we can give the generic 187 00:10:27,000 --> 00:10:28,000 URL. 188 00:10:28,000 --> 00:10:28,000 Okay. 189 00:10:28,000 --> 00:10:34,000 And uh, we can also say, uh, whether I want to add the video information or not. 190 00:10:34,000 --> 00:10:42,000 So here there will be one more parameter which is called as add ad underscore video underscore info 191 00:10:42,000 --> 00:10:43,000 is equal to true. 192 00:10:43,000 --> 00:10:45,000 I'll keep it as true okay. 193 00:10:45,000 --> 00:10:49,000 So these are the basic information with respect to. 194 00:10:49,000 --> 00:10:53,000 Whenever we upload a YouTube URL I should be able to load this okay. 195 00:10:53,000 --> 00:11:00,000 Otherwise in the else condition I know that if I'm giving a if the generic URL is in the form of website, 196 00:11:00,000 --> 00:11:07,000 I will be using this loader and we can go ahead and use this unstructured unstructured URL road. 197 00:11:07,000 --> 00:11:07,000 Right? 198 00:11:07,000 --> 00:11:09,000 This is also one kind of loader over here. 199 00:11:09,000 --> 00:11:11,000 And here we will just give our URL. 200 00:11:11,000 --> 00:11:15,000 The URLs will be nothing, but it will be a list of. 201 00:11:15,000 --> 00:11:17,000 I can also give multiple URL if I want. 202 00:11:17,000 --> 00:11:17,000 Okay. 203 00:11:17,000 --> 00:11:19,000 So here I will be having this multiple URL. 204 00:11:19,000 --> 00:11:25,000 One more thing, I will also go ahead and make some checks saying that hey uh, whether it should be 205 00:11:25,000 --> 00:11:28,000 SSL verified, you can probably keep it as true or false right now. 206 00:11:28,000 --> 00:11:30,000 I'll just keep it as false just to take any URL. 207 00:11:30,000 --> 00:11:33,000 If I'm given, I will probably go ahead and do this here. 208 00:11:33,000 --> 00:11:35,000 It should be generic underscore URL. 209 00:11:35,000 --> 00:11:36,000 Okay. 210 00:11:36,000 --> 00:11:40,000 And one more information along with this will be that, uh, the kind of header. 211 00:11:40,000 --> 00:11:48,000 See, whenever you work with any um, whenever you work with any kind of let's say you're serving from 212 00:11:48,000 --> 00:11:51,000 any, uh, browser, right. 213 00:11:51,000 --> 00:11:56,000 So in that browser, you basically set up some kind of headers by default so that just to validate your 214 00:11:56,000 --> 00:11:58,000 browsing from the right, uh, right. 215 00:11:58,000 --> 00:11:59,000 Browser itself. 216 00:11:59,000 --> 00:11:59,000 Right. 217 00:11:59,000 --> 00:12:03,000 So I will be keeping this specific information over here. 218 00:12:03,000 --> 00:12:07,000 And uh, this headers you will be giving it over here. 219 00:12:07,000 --> 00:12:07,000 Right. 220 00:12:07,000 --> 00:12:17,000 So headers like user agent Mozilla 5.0 Macintosh, Intel Mac OS, uh Apple WebKit uh like gecko, Chrome, 221 00:12:17,000 --> 00:12:17,000 Safari. 222 00:12:17,000 --> 00:12:20,000 So all these browsers are basically supportable. 223 00:12:20,000 --> 00:12:25,000 So that is the reason we are providing this entire information over here, uh, saying that if that 224 00:12:25,000 --> 00:12:31,000 information if this header is basically there in the website, we should be able to, uh, probably 225 00:12:31,000 --> 00:12:32,000 go ahead and use this. 226 00:12:32,000 --> 00:12:33,000 Okay. 227 00:12:33,000 --> 00:12:38,000 So this is the header that we are setting and unstructured URL loader will be making sure that it's 228 00:12:38,000 --> 00:12:41,000 just like how we browse in the browser. 229 00:12:41,000 --> 00:12:42,000 right? 230 00:12:42,000 --> 00:12:46,000 We are able to browse different, different pages and when we are browser, they're also headers will 231 00:12:46,000 --> 00:12:48,000 be set up with respect to every request. 232 00:12:48,000 --> 00:12:51,000 Now here also when we are using this unstructured URL. 233 00:12:51,000 --> 00:12:53,000 In short this is hitting this particular URL. 234 00:12:53,000 --> 00:12:59,000 So whenever we are hitting this particular URL, the web server will also be demanding the kind of headers 235 00:12:59,000 --> 00:13:04,000 you are putting on top of it with respect to user agent, from which browser it's just like from which 236 00:13:04,000 --> 00:13:06,000 browser you are trying to execute it. 237 00:13:06,000 --> 00:13:09,000 That information, you are able to put it over here. 238 00:13:09,000 --> 00:13:16,000 Okay, now once you are able to do this, the next, the next step, let me just show over here. 239 00:13:16,000 --> 00:13:22,000 So the next step over here will be that, uh, I will get this particular data. 240 00:13:22,000 --> 00:13:22,000 Okay. 241 00:13:23,000 --> 00:13:30,000 And uh, once we get this data so I will say, hey, one, once I have set up the loader, I'll say 242 00:13:30,000 --> 00:13:33,000 loader dot load and I will be getting the data itself. 243 00:13:33,000 --> 00:13:35,000 Okay, so this is done. 244 00:13:35,000 --> 00:13:38,000 This is enough over here with respect to the try block. 245 00:13:38,000 --> 00:13:40,000 Now we are going to initialize. 246 00:13:41,000 --> 00:13:49,000 It is always a good idea that we initialize the grok model outside our, uh, you know, our, our entire, 247 00:13:50,000 --> 00:13:52,000 our, uh, application. 248 00:13:52,000 --> 00:13:54,000 So here I will only initialize it over here. 249 00:13:54,000 --> 00:13:58,000 I'll say, hey, LM is equal to chat grok with all this information. 250 00:13:58,000 --> 00:14:00,000 And let's pick up the grok API. 251 00:14:00,000 --> 00:14:03,000 So grok API is basically coming from here. 252 00:14:03,000 --> 00:14:05,000 Um I will go and set it over here. 253 00:14:05,000 --> 00:14:05,000 Right. 254 00:14:05,000 --> 00:14:08,000 So this is where we are basically setting it up. 255 00:14:08,000 --> 00:14:09,000 I'm not just putting it inside. 256 00:14:09,000 --> 00:14:15,000 I could have loaded my, uh, grok over here, but here will be my grok API. 257 00:14:15,000 --> 00:14:15,000 Okay. 258 00:14:15,000 --> 00:14:21,000 And with respect to this grok, this will be my gamma model that I'm using. 259 00:14:22,000 --> 00:14:24,000 Uh, using grok API right. 260 00:14:24,000 --> 00:14:25,000 Grok API. 261 00:14:25,000 --> 00:14:30,000 Once this is done, uh, we will also go ahead and set up our prompt template. 262 00:14:30,000 --> 00:14:30,000 Okay. 263 00:14:30,000 --> 00:14:33,000 So here I'm just going to go ahead and write my prompt. 264 00:14:33,000 --> 00:14:36,000 Template prompt template. 265 00:14:36,000 --> 00:14:42,000 And for this prompt template I'm going to specifically use a simple prompt template. 266 00:14:42,000 --> 00:14:44,000 Say I will just use this. 267 00:14:46,000 --> 00:14:46,000 Okay. 268 00:14:46,000 --> 00:14:47,000 I'll write. 269 00:14:47,000 --> 00:14:47,000 Hey. 270 00:14:50,000 --> 00:14:55,000 Go ahead and right away provide a summary. 271 00:14:57,000 --> 00:15:07,000 Of the following content of the following content in 300 words. 272 00:15:07,000 --> 00:15:10,000 Okay, so this is what I'm actually going to give over here. 273 00:15:10,000 --> 00:15:15,000 And this will basically be my text, the text info that I'm actually going to put over here. 274 00:15:15,000 --> 00:15:16,000 Right. 275 00:15:17,000 --> 00:15:22,000 So so I'll just go ahead and say this is this and this is my content okay. 276 00:15:22,000 --> 00:15:26,000 The content is equal to text okay. 277 00:15:26,000 --> 00:15:30,000 And then after this what we do, we basically go ahead and define a prompt. 278 00:15:30,000 --> 00:15:33,000 So with respect to the prompt I will go ahead and use my prompt template. 279 00:15:33,000 --> 00:15:38,000 The template will be equal to my prompt template. 280 00:15:38,000 --> 00:15:47,000 And finally my input variables will be nothing but it will be equal to text right. 281 00:15:47,000 --> 00:15:50,000 So I have to basically give it as text. 282 00:15:50,000 --> 00:15:54,000 So perfect I think everything is working fine till here. 283 00:15:54,000 --> 00:16:02,000 So what I did is that instead of writing my prompt over here, I have defined the prompt template and 284 00:16:02,000 --> 00:16:03,000 lm outside. 285 00:16:03,000 --> 00:16:14,000 Okay, now it's time we go ahead and create our chain some chain for summarization okay, so for this 286 00:16:14,000 --> 00:16:16,000 you know what you we really need to use it. 287 00:16:16,000 --> 00:16:19,000 So I'll go ahead and say chain is equal to load summarize chain. 288 00:16:19,000 --> 00:16:23,000 And here I'm going to use my LM chain underscore type. 289 00:16:23,000 --> 00:16:27,000 Let's go ahead and use stuff initially okay. 290 00:16:27,000 --> 00:16:30,000 Because the content may be small or may be bigger. 291 00:16:30,000 --> 00:16:31,000 It is up to you. 292 00:16:31,000 --> 00:16:31,000 Right. 293 00:16:31,000 --> 00:16:35,000 So you can use stuff or map reduce or anything that you want. 294 00:16:35,000 --> 00:16:38,000 Uh, along with this I will just go ahead and define my prompt. 295 00:16:38,000 --> 00:16:39,000 Okay. 296 00:16:39,000 --> 00:16:40,000 So let's go ahead and write. 297 00:16:40,000 --> 00:16:42,000 My prompt is equal to prompt okay. 298 00:16:42,000 --> 00:16:47,000 And here we will go ahead and run the summary dot chain. 299 00:16:47,000 --> 00:16:48,000 Okay. 300 00:16:48,000 --> 00:16:56,000 So once I write uh sorry it should be summary is equal to or I'll just write output underscore summary 301 00:16:56,000 --> 00:17:00,000 is equal to chain dot run. 302 00:17:00,000 --> 00:17:03,000 And here I'm going to give my data okay. 303 00:17:03,000 --> 00:17:07,000 Or the data whatever data we are specifically getting uh over here instead of data. 304 00:17:07,000 --> 00:17:13,000 We will just go ahead and write docs because documents is what we usually get, right. 305 00:17:13,000 --> 00:17:16,000 So here also I will be giving my documents. 306 00:17:16,000 --> 00:17:16,000 Okay. 307 00:17:17,000 --> 00:17:17,000 Perfect. 308 00:17:17,000 --> 00:17:19,000 Till here everything looks good. 309 00:17:19,000 --> 00:17:22,000 And finally I will say TX dot success. 310 00:17:23,000 --> 00:17:24,000 Success right? 311 00:17:24,000 --> 00:17:28,000 And that is the reason you get green color in the demo, right? 312 00:17:28,000 --> 00:17:33,000 Uh, I will just go ahead and display my output summary. 313 00:17:33,000 --> 00:17:34,000 Perfect. 314 00:17:37,000 --> 00:17:37,000 Done. 315 00:17:38,000 --> 00:17:39,000 This is good enough. 316 00:17:39,000 --> 00:17:44,000 Now, in the accept block, we can probably go ahead and write our exception. 317 00:17:45,000 --> 00:17:50,000 So I will go ahead and write accept exception as E. 318 00:17:51,000 --> 00:17:54,000 And then we are just going to write TX dot exception. 319 00:17:57,000 --> 00:18:00,000 As exception. 320 00:18:01,000 --> 00:18:02,000 Colon e. 321 00:18:02,000 --> 00:18:03,000 Right. 322 00:18:03,000 --> 00:18:04,000 Perfect. 323 00:18:04,000 --> 00:18:05,000 So till here. 324 00:18:05,000 --> 00:18:06,000 Everything looks good. 325 00:18:07,000 --> 00:18:09,000 I think, uh, it should run. 326 00:18:09,000 --> 00:18:10,000 It should run. 327 00:18:10,000 --> 00:18:13,000 Okay, let's go ahead and execute it. 328 00:18:13,000 --> 00:18:15,000 So here I'm in my venv environment. 329 00:18:15,000 --> 00:18:19,000 Let's go back to my folder that is seventh text summarization. 330 00:18:19,000 --> 00:18:22,000 So I will go ahead and write seven text summarization. 331 00:18:22,000 --> 00:18:30,000 Here I will go ahead and write Streamlit run Streamlit run app.py. 332 00:18:30,000 --> 00:18:32,000 So let's go ahead and write App.py. 333 00:18:32,000 --> 00:18:35,000 Now I think everything should work fine. 334 00:18:35,000 --> 00:18:38,000 So this is my page. 335 00:18:38,000 --> 00:18:39,000 It looks fine. 336 00:18:39,000 --> 00:18:42,000 Grok API summarize the content from the YouTube website. 337 00:18:42,000 --> 00:18:44,000 Let me go back to my code. 338 00:18:44,000 --> 00:18:46,000 Let me open my env file. 339 00:18:46,000 --> 00:18:47,000 Right. 340 00:18:47,000 --> 00:18:51,000 And let me just pick up this grok API key. 341 00:18:51,000 --> 00:18:52,000 Right. 342 00:18:52,000 --> 00:18:53,000 All the API keys. 343 00:18:53,000 --> 00:18:55,000 You can specifically use it okay. 344 00:18:55,000 --> 00:18:57,000 Just to practice. 345 00:18:57,000 --> 00:19:00,000 So I'll press enter okay. 346 00:19:00,000 --> 00:19:02,000 Now let me do one thing. 347 00:19:02,000 --> 00:19:09,000 Let me use any website docs, Len Smith, whatever website you want I will go ahead and copy this. 348 00:19:09,000 --> 00:19:11,000 Put it over here. 349 00:19:12,000 --> 00:19:15,000 Um, module has no attribute exception. 350 00:19:15,000 --> 00:19:17,000 The reason exception. 351 00:19:17,000 --> 00:19:26,000 Okay, let's see this s t dot exception I think it should be in small letter okay. 352 00:19:26,000 --> 00:19:27,000 Now it should work. 353 00:19:29,000 --> 00:19:31,000 Always run I will summarize. 354 00:19:31,000 --> 00:19:36,000 So it is saying me to install this unstructured because we have used this unstructured over here. 355 00:19:36,000 --> 00:19:38,000 So let's go ahead and install this. 356 00:19:38,000 --> 00:19:42,000 And these are some of the errors that you may get if you missed any requirement. 357 00:19:42,000 --> 00:19:43,000 Dot txt right. 358 00:19:43,000 --> 00:19:46,000 And I want to show you all these errors okay. 359 00:19:46,000 --> 00:19:51,000 So quickly I will go ahead and open my another command prompt okay. 360 00:19:51,000 --> 00:19:57,000 So I'll say hey pip install please make sure that you do the installation in your v env environment 361 00:19:57,000 --> 00:20:01,000 right requirement dot txt once I do this. 362 00:20:03,000 --> 00:20:06,000 So here you'll be able to see this I think one more error. 363 00:20:06,000 --> 00:20:10,000 We may get it but let's see whether we'll get that error or not okay. 364 00:20:10,000 --> 00:20:16,000 So once this unstructured is basically getting installed YouTube transcript API I've already done it. 365 00:20:16,000 --> 00:20:18,000 Validators I have already done it. 366 00:20:18,000 --> 00:20:21,000 I think I do not have to probably get any kind of errors other than this. 367 00:20:21,000 --> 00:20:27,000 So now if I go ahead and summarize it, let's see. 368 00:20:27,000 --> 00:20:29,000 I think it should work. 369 00:20:29,000 --> 00:20:33,000 One more error can come again for the library. 370 00:20:33,000 --> 00:20:36,000 But I think other than that it should work okay. 371 00:20:38,000 --> 00:20:40,000 Why it is taking so much time. 372 00:20:41,000 --> 00:20:42,000 So it's better okay. 373 00:20:42,000 --> 00:20:43,000 Yeah. 374 00:20:43,000 --> 00:20:43,000 Perfect. 375 00:20:43,000 --> 00:20:45,000 So it shows you the output, right. 376 00:20:46,000 --> 00:20:48,000 Uh, let's try some other, uh, URL. 377 00:20:48,000 --> 00:20:49,000 Okay. 378 00:20:49,000 --> 00:20:56,000 So what I will do is that I will quickly go ahead and take some more URLs if I want. 379 00:20:56,000 --> 00:20:57,000 Okay. 380 00:20:57,000 --> 00:20:58,000 I can go and search for this. 381 00:20:58,000 --> 00:21:01,000 So let's take this entire URL. 382 00:21:02,000 --> 00:21:02,000 Okay. 383 00:21:02,000 --> 00:21:05,000 My entire page URL over here. 384 00:21:06,000 --> 00:21:10,000 And with respect to this particular URL, I will just go ahead and open this. 385 00:21:10,000 --> 00:21:14,000 And if you can try it with any YouTube channel video. 386 00:21:14,000 --> 00:21:16,000 Okay, so this is one of the URL. 387 00:21:16,000 --> 00:21:18,000 So it is necessary to properly test each and everything. 388 00:21:18,000 --> 00:21:20,000 So here I have given my YouTube video. 389 00:21:20,000 --> 00:21:23,000 I have to probably go ahead and install Pi tube okay. 390 00:21:23,000 --> 00:21:26,000 And this is one of the requirements I guess with transcript API. 391 00:21:26,000 --> 00:21:29,000 So I will quickly go ahead and copy and paste it over here. 392 00:21:29,000 --> 00:21:31,000 Let's go ahead and do the installation now. 393 00:21:31,000 --> 00:21:33,000 I think it should work okay. 394 00:21:34,000 --> 00:21:35,000 So basic basic requirements. 395 00:21:35,000 --> 00:21:39,000 And that is the reason you have to probably create an another environment for this. 396 00:21:39,000 --> 00:21:39,000 Right. 397 00:21:39,000 --> 00:21:43,000 So this is the version that you are having okay. 398 00:21:43,000 --> 00:21:45,000 So let's summarize. 399 00:21:47,000 --> 00:21:51,000 And now we should be able to get the output. 400 00:21:51,000 --> 00:21:52,000 Here you go. 401 00:21:52,000 --> 00:21:54,000 Right generative I explain. 402 00:21:54,000 --> 00:21:57,000 So yes uh this was it for my side. 403 00:21:57,000 --> 00:22:00,000 I hope you like this particular video and I hope you are liking the entire course. 404 00:22:00,000 --> 00:22:03,000 Uh, so yes, I will see you all in the next video. 405 00:22:03,000 --> 00:22:03,000 Thank you. 406 00:22:03,000 --> 00:22:04,000 Take care.
