Hello.
Welcome back.
In this lesson we are going to see how to install Python um Python packages.
I'm going to go to my installation folder I start my Python here.
This is the folder.
It's called Python 3 7 0.
Open it.
What we want to do it is we want to install the packages in this um in this folder Yeah.
No no script.
I'm going to double click to open it but we have to install it through the command prompt.
So one way we can install it in this forward from the command prompt is to go to the command prompt
and navigate to this folder that I wrote to do this would be to simply press shift on the keyboard right
click and then select open a command prompt here.
So when I do the as you can see command prompt brings me here.
Python 3 7 script so we're going to install a number of packages the first one we install is going to
be is what we call num pi.
So I'm going to say pip install I'm simply going to say Pip Pip is a way of installing packages on Python.
There are other ways but we use Pip here.
So I say pip install num pi and this is this is a library used for numerical analysis and numerical
computation.
It's arguably the most popular library in Python.
So once I've type this I've hit enter and it's going to pull it up and it's going to take a while
alright.
It's finished install it.
Okay.
Over here I have a warning saying I'm using an earlier version of Pip I'm using nineteen point two three.
There is a newer version nineteen point three one.
Okay.
You would see these errors a lot when you use it.
Pip you need not worry about it.
Now we're going to start the next package.
Um this one we call much plot lip so I'm going to do the same thing I'll say pip install mod plot and
lib like this and then I hit enter and we go through the same process
right.
Once this is done I'm going to install a plan in library or machine learning library known as KRS.
Also what I think is the most popular library for much learning out there.
Um but in this lesson we're not going to use any library for it in our deep neural network.
Later on I'll show you how to use this library.
So I'll say things though carers like this
isn't stolen
right.
It's done in stolen.
We're going to go on to the next one and we're going to install the imaging library a python imaging
library.
It's called Pil but we have to type it stored below.
So I'm gonna do pip install pillow like this
and it's done.
Next I'm going to install a library no not side by so I'll do pip install pi okay requirement already
satisfied.
Okay so say PI was installed when we were installing cameras.
Right.
Okay.
I think we've installed enough packages when we reach a point where we need a package which has come
back and continue install it in the next place and we will try some of these packages were installed.
So that's all there is.
If you have any questions at all just let me know and I'll see you in the next lesson.
Have a nice day.
Um before we conclude let's install tensile flow first so I'm going to do pip install
and then in terms of flow
and it's installing
still installing
right.
The installation is complete.
So now we have tons of flow already.
Also installed.
So like I mentioned earlier if if we we reach a point where we receive an arrow saying we've not installed
a package we just come back here and install it.
So she relates.
