pip install?

How can I use 3rd party modules, like https://pypi.org/project/pymorphy2/?
In general for local environment I install them with pip, which doesn't look to be possible in calibre python. How?

Assuming you have already created a personal Calibre GUI-type plugin designed to do what is necessary to interact with pymorphy2, hard-copy the pymorphy2 .py files into a subdirectory of the plugin source-code directory, and then "from xxxxx import ....." them into your plugin for use.

Thanks! I found pymorphy2 in sys.path, copied the folder from into my plugin folder, zipped, loaded my plugin into calibre, got error in debug mode:
ImportError: No module named pymorphy2

Any hints here?

That's a multi file package you wont be able to run it unmodified from inside a zip file, if it does not use relative imports, which older packages like this typically do not.

You could extract it from the zip file, add the extracted folder to sys.path and import it that way.
