Unable to load DLL python module in PyCharm. Works fine in IPython

Question

When I use the IPython included with Enthought Python Distribution, I can import the pyvision package just fine. However, when I try to import pyvision inside of PyCharm 1.2

Answer 1

I apologize for my explanation being long and probably not the best of clarity, but this is the best I could do to describe my experience.

I was having the same problem after first installation and this is how I solved it:

I had noticed there are some settings, as indicated in other answers, that tell pyCharm which interpreters and environment managers to use and I was sure the problem was with setting these options, but I was not sure how, so I started searching.

Setting interpreter

I had more or less followed the standard tutorial, assuming in some point I would have used newly created virtualenv inside my project folder. I was initially getting the DLL error, but as I made sure the interpreter settings were pointing at a valid executable.

Here it is explained how to do this.

Setting environment

at this point the error disappeared, but I had progressed towards a new error. The problem at this point I was not being able to import any module as they were not found. This is because I was working inside the newly created virtualenv, basically a pristine installation, with no modules installed. I am sure there are more evolved solutions (install modules in the virtualenv), but I was just looking for making the code to work, so I set the environment to use my anaconda usual development environment.

For me, with conda on windows (after activating the development environment with conda activate) then (see ..../anaconda-python-where-are-the-virtual-environments-stored for other systems). where python gives the path to the interpreter conda info --envs gives me the existing environment that I want to use.

This fixed everything for me.
