Python is amazing, but a hell to manage between different versions, dependencies in particular if you work with data analysis.<\/p>\n\n\n\n
Since a few version of some linux distributions, you are not allowed to install packages using pip. It’s a good thing as I broke my environment a few time due to inter-dependencies!<\/p>\n\n\n\n
You have to work with virtual environments. You have plenty of solutions, but I’ll focus on the one that work best for me. This tutorial is focused on Debian\/Ubuntu, but can be transposed to other environments.<\/p>\n\n\n\n Install pyenv<\/strong><\/p>\n\n\n\n PyEnv is a great way to manager different versions of python. <\/p>\n\n\n\n If you are not on Debian\/Ubuntu, read this information<\/a>.<\/p>\n\n\n\n Next install pyenv<\/p>\n\n\n\n Edit the .bashrc file and add at the end<\/p>\n\n\n\n Logout and login. <\/p>\n\n\n\n You can now install a specific version of python. As an example to install version 3.11.<\/p>\n\n\n\n Just copy the error in chatgpt if you see any issue \ud83d\ude42<\/p>\n\n\n\n <\/p>\n\n\n\n Check the version of python<\/strong><\/p>\n\n\n\n As an example, if you have installed 3.11.<\/p>\n\n\n\n Install and test venv<\/strong><\/p>\n\n\n\n Venv is a virtual environment where you can install your libraries and dependencies.<\/p>\n\n\n\n Create a folder with the name of your project (it’s easy to be lost!) and create a venv inside.<\/p>\n\n\n\n Activate this venv<\/strong><\/p>\n\n\n\n Activate this virtual environment. It’s the only thing you will need to use in the future!<\/p>\n\n\n\n Install libraries<\/p>\n\n\n\n You can use a file called “requirements.txt” to install libraries in many projects.<\/p>\n\n\n\n Bonus: to create this file once your environment is setup correctly.<\/p>\n\n\n\n If I want to install open-webui (a LLM web ui)<\/p>\n\n\n\n <\/p>\n\n\n\n I hope it answers many questions you had! Don’t forget that you have many different ways to do it, as an example by using conda, docket and other virtualization frameworks.<\/p>\n","protected":false},"excerpt":{"rendered":" Python is amazing, but a hell to manage between different versions, dependencies in particular if you work with data analysis.
