Package management

It is better to use conda (the package manager that comes with anaconda), since this makes it easier to work with conflicting package libraries (a bit like a package lock).
The alternative is the native pip but you have to create virtual environments (venv) to manage packages at different versions.

It works a bit like this:

To make use of virtual environments in pip you have to create the virtual environment before installing anything:
```
python3 -m venv venv3
source venv3/bin/activate
pip [library_name]
```
pypi.org > is package registry like NPM
