GPy and Matplotlib missing in setup.py

[labodyn]

While executing pip install gpyopt:

  File "/home/lander/miniconda3/envs/gpyopt/lib/python3.6/site-packages/GPy/plotting/__init__.py", line 18, in change_plotting_library
    import matplotlib
ModuleNotFoundError: No module named 'matplotlib'

Do you still have the problem?

When installing in fresh environment with pip install gpyopt, I had the same error again for numpy. After installing numpy manually, the gpyopt package could be installed.

It is issue with gpy.

It seems that PyPI doesn't have a wheel for it, so sdist is used.

Plotting libraries in gpy are optional, and are controlled by the library's .cfg file. The default-enabled library is matplotlib, but it's possible to disable all plotting libraries by setting the value to 'none'. This causes breaks in GpyOpt (not Gpy) in GPyOpt\plotting\plots_bo.py, since it assumes pylab is installed (which is not a declared dependency of GpyOpt and won't be present in Gpy if the plotter is changed to something other than the default).
