About free of charge libraries - Mahzinho93 - May-12-2021 Hello, how are you? I am Marcos, a new-coming programmer mainly with Python (marvelous language for computing general tasks) and I want to know: I installed these libraries through CMD (Administrator) from Windows 10: Bokeh Pypi iPython Cython MatplotLib Pandas torch pymc Numba Keras Regex Numpy And am planning to install more for more compatibility/management about what I will be able to do. I am using Spyder5 as my main IDE. These libraries are free of charge? 100% free of charge and the rest I didn't install yet are too? Ah! When a new version come I just download it and uninstall Python 3.9.5? And... am I wrong to install from CMD? I installed Spyder5 outside CMD and the instructions (libraries) throught this. Thank you people! RE: About free of charge libraries - Larz60+ - May-12-2021 You should be using virtual environments for each project. This can be easily done by: Create a new directory for your project. cd to directory just created, and run from command line python -m venv venv Activate the virtual environment (I am a Linux person, but believe the windows 10 command is): venv\Scripts\activate Now form command line, install only the packages needed for the project using pip example: pip3 install requests Now you have a custom environment for the project which is streamlined specifically for that project. In addition to above, you can also control the python version used with each project, see: pyenv Simple Python Version Management
