Edit: Offline Python Packages Installation

Title

Description

Content (Markdown supported)

Imagine a senario that we need to install a particular Python version together with all the dependencies on a computer with no internet connection, or we need to simply move a Python venv to another machine without internet.

I. Create a requirements.txt
```shell
(venv) [...]$ mkdir pkgs
(venv) [...]$ cd pkgs
(venv) [...]$ pip freeze > requirements.txt
```

II. Download the pip packages on your pc with the requirements.txt 
```shell
(venv) [...]$ pip download -r requirements.txt
# You must take care to use the same python version 3.8.6..., maybe the same pip version, too. You can create a venv to do that to save time. 
```

III. Copy the pkg folder (Inside it will be all packages (files with .whl extension usually) and the requirements.txt file) into the PC with no internet connection.  
IV. Create a new virtual environment and install packages on the remote computer
```shell
(venv) [...]$ cd /the/path/to/pkgs
(venv) [...]$ pip install -r requirements.txt --no-index -f . 
# The dot in the end is the path where the packages are.

# or
(venv) [...]$ pip install -r requirements.txt --no-index -f /the/absolute/path/to/pkgs
# --use-pep517
```
