I could not find any documentation on how to enable debug logging mode.

I did some debugging and seem to have fixed the problem.

My TEMP directory is on a RAM disk (IMDisk). The drivers apparently don't work too well with Pyfa and prevent the plotting library from being loaded correctly. I switched to another RAM disk (SoftPerfect RAM Disk) and the problem is gone.

While the issue thus can be closed, it still would be very interesting to know what exactly in pyfa's code caused IMDisk to malfunction.

I believe it is not pyfa's code but something related to matplotlib (the graphing library we're using). It's quite a complex product, so if you are truly interested in that, might ask its maintainers.
