problem with GPy #8

Closed kayhan-batmanghelich closed 8 years ago

kayhan-batmanghelich commented 8 years ago

Hi Scott and Matt,

Really sorry that I am sending the second issue in one day. I interested to use pgmult with GP which is explain in examples/multinomial_gp.py. 

$ python examples/multinomial_gp.py
This program needs access to the screen.
Please run with a Framework build of python, and only when you are
logged in on the main display of your Mac.

It seems it is an issue with GPy but not sure. If you feel this is not relevant to your package, please close it.

Thanks, Kayhan

It seems the issue is with wx backend. If I run the code with pythonw examples/multinomial_gp.py it runs.

Hmm so should we close this issue, or is there something to fix in pgmult here?

kayhan-batmanghelich commented 8 years ago

multinomial_gp.py needs GPy package and GPy needs wx. I opened this issue with GPy:

https://github.com/SheffieldML/GPy/issues/387

It seems wx is somewhat broken in mac if I understand it correctly from here:

http://matplotlib.org/faq/virtualenv_faq.html

So, you can close this issue. I don't think you can fix it because there is something wrong with GPy dependency.

Thanks,

Cool, thanks for the thorough investigation!

Response from the GPy issue: " Yes try using python3 and import matplotlib before importing GPy. Also look at your ipython config, which should say backend=macosx. "

can I use pgmult with python3 ?

mattjj commented 8 years ago

I don't think we've ever tried it so there would probably be some bumps with python 3, but nothing should be impossible to update.
