Module or Incorrect Python Version Problem?

I'm installing a bunch of python modules on my system that are specific to this code I am going to be working with. Specifically, I used pip install pyda to get the pyda module. To make sure I had gotten all the modules, I went through and ran some of the code snippets, and came across the following error: ModuleNotFoundError: No module named 'pyda.utilities'

I tried using pip install pyda.utilities, but that honestly doesn't make sense, it should have just come with the pyda module. According to this website https://pypi.org/project/pyda/ it seems like it should come with the package. I tried determining if I just installed it in the wrong python version, but I'm having a difficult time forcing it to use the specific python version that I installed the module in (specifically, I tried to create an alias for /usr/bin/python3.7 or something like this as I have seen on other websites, but it just fusses at me that this is simply a directory, incredibly unhelpful because I can't find the corresponding executable, so I'm a bit confused here).

This is a very long question likely with a very simple answer, any thoughts or help on what the issue might be would be appreciated.

Edit: I have determined that it's a package problem, not a python problem. The command 'pip install pyda' is not actually installing everything, oddly enough, which is why it cannot find the pyda.utilities module. Unfortunately, I think this means I will have to install the package manually. I will keep this question posted because of the useful answer on virtual environments, so thanks everyone.

The answer is indeed straightforward. As @Chris indicated in the comments, start using virtual environments.

It's not as complicated as it sounds and there's plenty of tutorials on getting started with virtualenv for Python, like https://uoa-eresearch.github.io/eresearch-cookbook/recipe/2014/11/26/python-virtual-env/

The basic steps:

  • check you're using the version of Python you want in your virtual environment
  • if you don't, change directories to where it lives
  • ensure you have pip and it works
  • check if you have virtualenv and if you don't pip install virtualenv
  • create a virtual environment virtualenv /your/env/folder/here
  • activate the virtual environment with /your/env/folder/here/Scripts/activate

After that, just install the packages you need with pip and they will end up in your virtual environment, with no interference from other Python versions or packages.

Check your python version, if it does not work restart your computer and try run setup.py install on the python command line
