Currently, in Python 3-based Kodi builds some binary Python modules are either missing or incorrectly built like in this case. This should be fixed in the future. As a temporary workaround you can download a compiled Python 3.6 wheel for your platform from PyPI and replace the contents of script.module.pil/lib folder in your Kodi installation. A Python .whl package is just a ZIP file but with different extension.
