Answer 1

I think you want this:

pip install statsmodels

You're trying to install one submodule of a Python module/package. You have to install the whole package.

If you've already done this, then you already have the statsmodels.api module and don't have to install anything else.

Answer 2

I do not know how you have configured your environments (if you have many). but ensure that you install your package in the correct environment. However, please try the following for me:

 conda install -c anaconda statsmodels
