00:00:00,920 --> 00:00:01,220
Hello.

2
00:00:01,260 --> 00:00:01,970
Welcome back.

3
00:00:01,980 --> 00:00:07,810
In this lesson we're going to see how to install some Python packages and modules.

4
00:00:07,820 --> 00:00:10,760
So let's go back to our installation folder.

5
00:00:10,770 --> 00:00:15,450
I kept mine and documents Python 37 so I come here open it.

6
00:00:16,140 --> 00:00:21,360
And what we want to do is we want to install them in this forward and on script and we are going to

7
00:00:21,360 --> 00:00:23,430
use something known as pip install.

8
00:00:23,520 --> 00:00:30,030
So we need to go to the command prompt and navigate to this folder and do the installation here.

9
00:00:30,090 --> 00:00:33,120
So there are two ways to navigate to this folder.

10
00:00:33,150 --> 00:00:38,970
We could do it the hard way or the easy way the hard way would be to go to windows command prompt and

11
00:00:38,970 --> 00:00:47,340
type this entire path and type this one here or we could just come to this folder using a shortcut to

12
00:00:47,340 --> 00:00:47,790
do that.

13
00:00:47,790 --> 00:00:53,700
What I'm going to do it I'm going to highlight this by just come in here right click and then press

14
00:00:53,700 --> 00:00:55,110
the left shift button.

15
00:00:55,140 --> 00:01:00,660
So I'm pressing the let's shift button and then I'll right click and when I right click I have this

16
00:01:00,680 --> 00:01:04,140
copy I have this option here open the command window here.

17
00:01:04,500 --> 00:01:13,310
So if I click here then it's open it directly see uses ISRO document Python 3 7 scripts.

18
00:01:13,470 --> 00:01:14,830
So come over here.

19
00:01:14,850 --> 00:01:15,660
Right.

20
00:01:15,720 --> 00:01:16,950
So the step is simple.

21
00:01:16,950 --> 00:01:18,790
First you highlight this.

22
00:01:18,840 --> 00:01:24,490
You press down let's shift your right click and then you select open command window here.

23
00:01:24,600 --> 00:01:31,560
Once that is done we're going to store three modules we need three special modules for this DSP cause

24
00:01:31,860 --> 00:01:38,310
we need to multiply Talib which is going to help us in plot in our signals we need a num Pi which is

25
00:01:38,310 --> 00:01:45,490
going to be used for various numerical problems and then we need a side PI we need a module and a outside

26
00:01:45,510 --> 00:01:45,880
pi.

27
00:01:46,110 --> 00:01:48,750
So let's start with Mark Plotkin they've already have.

28
00:01:49,170 --> 00:01:53,970
So I'm going to type the command module written a very short statement by yours would take about two

29
00:01:53,970 --> 00:02:01,920
minutes to complete installation so to install much plot lib all I need to do a c p IP for Pip and then

30
00:02:01,930 --> 00:02:08,970
install and then mod plot led like this and then I'll hit Enter

31
00:02:12,770 --> 00:02:18,110
minimize this and then what does it say minus already installed.

32
00:02:18,310 --> 00:02:24,010
So that's why I'm getting this message although it says you are using PID version 10 points you are

33
00:02:24,010 --> 00:02:27,700
one however version A and is available.

34
00:02:27,710 --> 00:02:35,660
Okay so I need not worry about this upgrade my Pip later but this is it my much plot Labor's already

35
00:02:35,670 --> 00:02:37,970
installed and when you read here.

36
00:02:38,020 --> 00:02:43,900
So sometimes when you install in a package it requires certain dependencies and if you're lucky sometimes

37
00:02:43,900 --> 00:02:46,570
it would install these dependencies for you.

38
00:02:46,570 --> 00:02:53,230
Other times you may need to store the dependencies on your own before you are able to to proceed with

39
00:02:53,230 --> 00:02:54,190
what you want to install.

40
00:02:54,190 --> 00:03:01,010
For instance it says requirement already satisfied and overhead seen num pi it's installed num pi and

41
00:03:01,020 --> 00:03:06,070
it's caught under requirement here it says satisfied and this is known as.

42
00:03:06,540 --> 00:03:08,130
And it's called fairest requirement.

43
00:03:08,200 --> 00:03:09,530
So just do it.

44
00:03:09,580 --> 00:03:15,280
I'm sure you've typed and it's probably taken a while to complete installation so once that is installed

45
00:03:15,370 --> 00:03:16,590
we move onto the next.

46
00:03:16,660 --> 00:03:24,750
So now let's install say pi we're going to do the same thing we use P IP for Pip and then install and

47
00:03:24,760 --> 00:03:30,830
then SC IP y for site pi and then enter and then this going to take a while.

48
00:03:31,030 --> 00:03:37,420
It starts by collecting it and then installing it so the installation is complete.
