Error running visualization.py

I have downloaded everything in the tutorial but get "python3: can't open file 'visualization.py': [Errno 2] No such file or directory" when I try to run "sudo python3 visualization.py scroll"

Are you in the Python directory? If not, go in there first and then try the visualization command again. e.g:

cd python
sudo python3 visualization.py scroll

I was not in the python directory, but when I try "cd python" it says it is not a directory. After reading your comment I realized I did not have the latest version of python installed (I was still on 2 something) so I installed python 3.9 and replaced the old version in /usr/bin, but it still says python is not a directory. I see the folder for python and such, do I need to manually make python a directory and assign the files there or was that something that should have happened in the install?

I realized that I needed to be in the python directory for the project. Now I am getting an error saying "No module named numpy", but when I check it is installed, does it need to be in a certain folder?
