Beyond the Standard Library
Chapter 3: Pip
Installing packages
You will install the following packages to your virtual environment. You will need them anyway for our upcoming lessons!
- numpy
- scipy
- matplotlib
- pandas
- scikit-learn
Installing a package is as easy as running pip install <package_name>.
For example, pip install numpy will usually install the latest version of NumPy from PyPI.
You can also install specific versions, e.g. pip install numpy==1.21.3.
You can also install multiple packages in a single line:
(my_env) user@MACHINE:~/ai_project$ pip install numpy scipy matplotlib pandas scikit-learn
Once you are done installing, you can try listing your packages again. You will see the packages installed (along with many other dependencies).
(my_env) user@MACHINE:~/ai_project$ pip list
