1 00:00:04,600 --> 00:00:12,820 In this lesson we will talk about the modifications introduced by the long chain V010 version. 2 00:00:15,390 --> 00:00:21,120 As always, you will find more detailed information in the attached materials, in this case with a 3 00:00:21,120 --> 00:00:25,980 notebook with text and code about the new long chain version. 4 00:00:27,920 --> 00:00:33,560 Remember that we have been talking about the changing environment around the LLM applications. 5 00:00:34,250 --> 00:00:38,690 These have this has advantages and disadvantages. 6 00:00:39,440 --> 00:00:48,890 The advantages are that if you keep updated, you will be among the few that master a this new field. 7 00:00:48,890 --> 00:00:58,010 And the disadvantages is that, uh, if you uh, if you lose track of the changes, you will be immediately 8 00:00:58,010 --> 00:01:06,590 behind the a elite of professionals that master this new field. 9 00:01:07,670 --> 00:01:09,290 So remember what we said. 10 00:01:09,290 --> 00:01:16,250 The environment around LM applications is very, very new and is changing one year from now. 11 00:01:16,250 --> 00:01:24,530 It can be very different from today and you must get used to a change in your profession. 12 00:01:24,530 --> 00:01:29,600 Remember that especially frameworks like Long Chain are evolving. 13 00:01:29,600 --> 00:01:34,070 Remember that we have been talking about the first and second version of Long Chain. 14 00:01:34,070 --> 00:01:43,430 So this, uh, version 010 is like the third version of Long Chain. 15 00:01:43,430 --> 00:01:50,600 We will talk a little bit more about that, and you will see that they seem to be leaning towards the 16 00:01:50,600 --> 00:01:53,960 long chain extension expression language. 17 00:01:53,960 --> 00:01:55,580 So the second version. 18 00:01:55,580 --> 00:01:58,490 But we will talk about that later. 19 00:01:59,400 --> 00:02:13,050 So this is version 010A was released uh, in the mid of January 2024, and the launching team said that 20 00:02:13,050 --> 00:02:18,600 the main purpose was, uh, you know, to have a more stable version. 21 00:02:18,600 --> 00:02:28,860 Um, but our, uh, personal impression is that the main goal of this version is to facilitate a long 22 00:02:28,860 --> 00:02:29,940 chain updates. 23 00:02:29,940 --> 00:02:38,130 So the previous updates, uh, in long chain has been had been a little bit problematic. 24 00:02:38,130 --> 00:02:49,320 So our, uh, feeling is that this a new version and the changes that it introduces are, uh, preparing 25 00:02:49,320 --> 00:03:01,710 the way of the future for new updates and, uh, changes in the framework in a more professional manner. 26 00:03:01,980 --> 00:03:07,890 Uh, it they say that this new version should not affect apps. 27 00:03:07,950 --> 00:03:17,880 Uh, but what we see is that it is probably not affect apps in production that keep a very, uh, careful 28 00:03:17,880 --> 00:03:21,750 track of the versions of every package they are using. 29 00:03:21,750 --> 00:03:28,740 But probably it will affect most demos, because when when you are preparing a demo, usually you are 30 00:03:28,740 --> 00:03:36,240 less careful about the details, like, uh, for example, every package, a version. 31 00:03:38,620 --> 00:03:48,100 So the main change of this new version is that the the previous Lang chain package is now divided in 32 00:03:48,100 --> 00:03:50,200 several different packages. 33 00:03:50,230 --> 00:03:56,890 They say they do this because it is going to make it easier for them to update every package. 34 00:03:56,890 --> 00:04:06,550 So right now we have a several different packages and the main ones are Lang Chain core and Lang chain 35 00:04:06,970 --> 00:04:09,040 community and chain. 36 00:04:09,040 --> 00:04:16,570 Core is for launching functionality and launching and launching communities for launching integrations. 37 00:04:16,570 --> 00:04:23,440 But keep in mind that some special integrations like, for example, OpenAI, have. 38 00:04:24,530 --> 00:04:26,240 A special partner. 39 00:04:26,240 --> 00:04:27,170 Packages. 40 00:04:30,620 --> 00:04:36,410 So these changes are going to affect in several areas. 41 00:04:36,410 --> 00:04:37,850 The first one is the. 42 00:04:38,820 --> 00:04:45,900 The area where we import the packages we need in a, in a in a program before. 43 00:04:45,900 --> 00:04:54,690 For example, if we were importing OpenAI, as you know, we would write from land change LMS import 44 00:04:54,690 --> 00:05:03,150 OpenAI right now with this new land change OpenAI package, we are importing OpenAI, as you see in 45 00:05:03,150 --> 00:05:04,920 the screen from land change. 46 00:05:04,950 --> 00:05:07,740 OpenAI import OpenAI. 47 00:05:09,210 --> 00:05:19,530 This has also effects in the way we import packages, or we install packages in terminal for example. 48 00:05:19,530 --> 00:05:28,290 So if you remember in the previous versions of Long chain, when we started a project, if we have a 49 00:05:28,290 --> 00:05:36,180 new a virtual environment and we we need to install the packages from from scratch, we would install 50 00:05:36,180 --> 00:05:38,430 long chain as a whole package. 51 00:05:38,430 --> 00:05:43,680 And we will write in the in the terminal pip install long chain. 52 00:05:44,130 --> 00:05:47,940 Or if we were in the in the notebook we will wait. 53 00:05:47,940 --> 00:05:52,290 We will write exclamation mark pip install long chain. 54 00:05:52,290 --> 00:06:02,070 When we write exclamation mark pip in in the in the notebook, we are giving the notebook an instruction 55 00:06:02,070 --> 00:06:06,450 in order to execute a command like in terminal, right? 56 00:06:06,450 --> 00:06:14,340 So writing exclamation mark pip install long chain in a notebook is exactly the same. 57 00:06:14,340 --> 00:06:18,750 Like if you write pip install long chain in your terminal. 58 00:06:19,350 --> 00:06:29,520 By the way, if you are a reading one of the notebooks, a of the exercises we provide, and you find 59 00:06:29,520 --> 00:06:39,540 a pound sign before exclamation mark pip, install this pound sign as probably many of you know, mean 60 00:06:39,660 --> 00:06:42,420 means a comment out. 61 00:06:43,240 --> 00:06:53,500 Commenting out a sentence in a in a computer, in a software program, a means that a the computer is 62 00:06:53,500 --> 00:06:56,860 not going to read what it is in that line. 63 00:06:56,860 --> 00:07:06,370 So when we use pound sign in the notebooks we are trying to avoid to install again one package that 64 00:07:06,370 --> 00:07:08,170 we have already installed. 65 00:07:08,170 --> 00:07:16,600 So when we write the the notebook and the initial line is exclamation mark, pip, install, whatever. 66 00:07:16,600 --> 00:07:26,170 But when we save this notebook, we write a pound sign before the exclamation mark pip install because 67 00:07:26,170 --> 00:07:34,180 we don't want to reinstall the package again whenever we open the notebook is is is not necessary and 68 00:07:34,180 --> 00:07:35,740 it's just a waste of time. 69 00:07:35,740 --> 00:07:39,340 So that's that's the reason why you would see the pound sign. 70 00:07:39,340 --> 00:07:48,370 So if it is the first time for you installing this, uh, whatever, whatever module it is, just remove 71 00:07:48,370 --> 00:07:55,210 the pound sign and execute the cell with exclamation mark pip install whatever. 72 00:07:55,240 --> 00:07:55,780 Okay. 73 00:07:55,780 --> 00:07:59,890 And then if you want, you can, uh, write the pound sign again. 74 00:07:59,890 --> 00:08:02,200 So it is commented out. 75 00:08:02,890 --> 00:08:13,000 So in, in this area of installing modules in terminal or in notebook, you would say that this changes 76 00:08:13,000 --> 00:08:17,530 in the version 010 of land chain means. 77 00:08:17,530 --> 00:08:26,410 That means that, uh, we now will have to install new packages like long chain OpenAI and long chain 78 00:08:26,410 --> 00:08:34,659 Community and pay attention, because when we install the package, the hyphen here is different from 79 00:08:34,659 --> 00:08:43,179 the hyphen we are going to use when we are importing inside the, uh, Python program. 80 00:08:43,179 --> 00:08:43,570 Okay. 81 00:08:43,570 --> 00:08:46,060 So just keep this in mind. 82 00:08:46,900 --> 00:08:56,440 Another, uh, effect of this change of the 010 version of long chain is what we call the deprecated 83 00:08:56,440 --> 00:08:57,430 warning. 84 00:08:57,700 --> 00:09:07,330 So a although the classic version of Long Chain keeps working in most cases, like 99% of the cases. 85 00:09:08,090 --> 00:09:17,840 Sometimes, and I would say a bit often we are going to receive warnings saying that some elements of 86 00:09:17,840 --> 00:09:21,470 our classic land chain will be deprecated. 87 00:09:21,470 --> 00:09:28,580 Not now, not now, not in the version 010, but in the next version. 88 00:09:28,580 --> 00:09:37,250 Okay, so this is just a like a reminder of a long chain saying as that some elements like for example 89 00:09:37,250 --> 00:09:41,480 the dot run element are going to be deprecated. 90 00:09:41,480 --> 00:09:48,800 They will be replaced by new ones like for example, invoke in this case in the next version of long 91 00:09:48,800 --> 00:09:49,100 chain. 92 00:09:49,870 --> 00:09:53,590 When will we have the next version of Land Chain? 93 00:09:53,620 --> 00:10:00,580 We don't know, but we suspect that it is not going to be soon. 94 00:10:00,580 --> 00:10:11,230 So usually before you reach the version 020, you are going to reach the 011, then the zero, one two, 95 00:10:11,230 --> 00:10:13,150 etc. etc. but let's see. 96 00:10:13,180 --> 00:10:20,440 Long chain is very young and we don't know what are going to be the the patterns they follow. 97 00:10:21,240 --> 00:10:28,230 So this warning here deprecated that you are going to see in some of the exercises that we provide. 98 00:10:28,230 --> 00:10:29,820 It doesn't mean anything. 99 00:10:29,820 --> 00:10:31,230 The exercise works. 100 00:10:31,230 --> 00:10:37,890 It is only telling you that the classic version we are using is not going to be. 101 00:10:38,700 --> 00:10:46,710 The the preferred one in the next version, but right now works perfectly fine. 102 00:10:47,130 --> 00:10:57,690 So as a consequence of this change, that, as I am telling you, occur on January 2024, we had to 103 00:10:57,690 --> 00:10:59,970 include some changes in our program. 104 00:10:59,970 --> 00:11:05,520 So all our exercises and demos were, uh, already prepared. 105 00:11:05,790 --> 00:11:13,830 And we have review all of them in order to confirm that they are working properly. 106 00:11:14,430 --> 00:11:22,440 And what we have seen is that we needed to include some changes in almost 100% of them. 107 00:11:22,440 --> 00:11:30,480 So you will see that even when in the explanatory videos that we provide with the exercises. 108 00:11:30,480 --> 00:11:38,100 You see, for example, that when you import OpenAI, OpenAI, uh, we use the classic way like from 109 00:11:38,100 --> 00:11:45,510 lunch change LMS, uh, in import OpenAI in the attach notebook. 110 00:11:45,510 --> 00:11:48,600 We have corrected that way. 111 00:11:48,600 --> 00:11:54,630 And you will find now from on chain OpenAI import OpenAI. 112 00:11:54,660 --> 00:11:55,050 Right. 113 00:11:55,050 --> 00:11:59,580 So you will see you will see you will see minor changes like that. 114 00:11:59,580 --> 00:12:03,870 And we have done that in order to avoid that. 115 00:12:03,870 --> 00:12:10,830 The notebooks, when you execute the notebooks in your computer a work properly. 116 00:12:10,830 --> 00:12:11,430 Right. 117 00:12:11,430 --> 00:12:13,110 So just keep that in mind. 118 00:12:13,110 --> 00:12:20,580 So the notebooks of the basic launching block, the notebooks of the launching expression language, 119 00:12:20,580 --> 00:12:27,090 block the notebooks of the A level up level one apps block. 120 00:12:27,120 --> 00:12:36,600 And also the code associated with the level two apps and level three apps has all of the all of them 121 00:12:36,600 --> 00:12:41,730 have been a updated in order to introduce these changes. 122 00:12:41,730 --> 00:12:50,940 So basically we have we have changed the way we import some of the modules and also the way we install 123 00:12:50,940 --> 00:12:54,480 some of the some of the packages from the notebooks mostly. 124 00:12:54,480 --> 00:12:54,990 Okay. 125 00:12:54,990 --> 00:12:59,040 So just keep that in mind in the documentation. 126 00:12:59,040 --> 00:13:07,290 In the attached documentation you are going to find a notebook with a the main line chain. 127 00:13:07,590 --> 00:13:11,730 Uh 010 version changes. 128 00:13:11,730 --> 00:13:18,420 We are based this notebook in the Quick Start guide provided by launch. 129 00:13:19,140 --> 00:13:25,140 In this notebook, we are including a couple of, uh, sources from Long Chain. 130 00:13:25,140 --> 00:13:31,200 One is the blog post they provided when they launch this new version of Long Chain. 131 00:13:31,200 --> 00:13:38,400 And the other is a video from the CEO of Long Chain explaining why the changes and, you know, giving 132 00:13:38,400 --> 00:13:40,020 some details about them. 133 00:13:42,060 --> 00:13:53,310 So in this lesson, we have been talking about the modifications that the version 010 of Long Chain 134 00:13:53,310 --> 00:14:04,530 has introduced and how we have applied these modifications in our, uh, in our exercises.
