Background: while running Jupyter Notebook a new import was failing even though the library was installing successfully using pip3. Some of the set up for the code I was running was done in PyCharm which was using a virtual Python 3.8.2 environment. The failing import library is in the virtual environment so why isn't Jupyter seeing it?
I went looking and found that there are multiple versions of Python installed:
- /Library/Python/2.7
- /Library/Frameworks/Python.framework/Versions/3.8
- /usr/local/bin/python3
- /usr/local/bin/python3.8
- /usr/local/bin/jupyter (included this in case it clarifies things)
- /usr/bin/python
- /usr/bin/python3
- /usr/local/Cellar/python/3.7.6_1
- /Users/xxx/anaconda3/bin/python3.7 (anaconda was uninstalled months ago so why is this still here?)
- /Users/xxx/git/moat-ds/venv/lib/python3.8
I have installed pyenv and virtualenv and tried (unsuccessfully) to sort things out through this and similar articles. But all of this has only left me with questions:
- what are these different directories doing?
- when launched what is Jupyter notebook using for 'python 3' kernel?
- where are the python packages stored when I run pip3 at the CLI (in pycharm packages are put in the \venv folder but otherwise?)
