jupyter notebook is kicking my ahh

I'm a 28yo student learning data science and AI through an online graduation degree course. Ngl I did Not realize this would be as difficult as it is proving to be.

I am unable to even do a project 5% (stuck in the titanic dataset) because all the time goes into setting up a venv for my notebook and then solving every single problem that comes up while doing that.

Can someone here help me with some videos or tutorials that kind of help me understand how virtual environments, and installing pandas and numpys and everything for those separately even if you have those installed on your system and everything works?

I'm tired of solving problems as they arise without knowing the basics of it all.

Also any help with how to get ahead of this all will help, I'm scared and really want to improve!
