Import fails due to bad naming scheme.

This is the error message.

This interpreter version: '3.6.0' doesn't match with version of the interpreter ViZDoom was compiled with: 3.6

Temporary solution:
Simply go to vizdooms __init__.py and change the line _COMPILED_PYTHON_VERSION = "3.6" to _COMPILED_PYTHON_VERSION = "3.6.0".

This should probably be handled better in a future version.

Hi @biggzlar,
thank you for reporting, could you provide information about your OS, CMake version and python distribution? In most cases version extraction works properly.

Hi @mwydmuch,
thanks for your reply. Here are my system details:

OS: macOS High Sierra 10.13.4
CMake: 3.8.2
Python: 3.6.0, running in virtualenv version 15.1.0

Had this exact same issue with Python3.8.

Could not install vizdoom from pip - I still don't know why, but I decided to just build from source instead of trying to debug make via the Python build script.

Built with the same virtual environment activated that I subsequenty tried to import vizdoom under.

Built vizdoom successfully and copied the build/bin/python3/pip_package directory into my site packages as vizdoom.

Tried to import vizdoom and got this error message:

>>> import vizdoom
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/fuzzyfroghunter/dev/vizdoom/.vizdoom/lib/python3.8/site-packages/vizdoom/__init__.py", line 8, in <module>
    raise SystemError(
SystemError: This interpreter version: '3.8.0' doesn't match with version of the interpreter ViZDoom was compiled with: 3.8

Just going to go and modify the version in the <site-packages>/vizdoom/__init__.py, but I'd like to know what the underlying issue is. Reproducing my current installation process would be hacky.

Hope that helps. Would really like to understand why the pip install didn't work, but perhaps that should be a separate bug.

Hmm. I just tried with conda environment on Ubuntu 16.04 LTS (cmake 3.10.2, python 3.8.3), and both pip install vizdoom and pip install git+https://github.com/mwydmuch/ViZDoom install vizdoom correctly. The former does throw a compilation error, but it still did work expected (importing, creating and initializing DoomGame works).

This was fixed some time ago, so I'm closing the issue.
