Reduce verbose / loudness when running a minimiser in a notebook

[andreufont]

Hi again - When I run the minimiser (default settings) in a Jupyter notebook, I get a fairly long list of output lines about the progress of the minimiser. In my tests, the minimiser takes a few seconds, but it is enough to really polute my nice, tidy notebooks :-)

It is possible to make the minimiser quiter? I tried looking at the documentation, but it wasn't trivial. I also tried guessing things like "silence=True", "debug=False", "verbose=False", but none of these wild guesses did the trick.

Thanks for the great work!

For BOBYQA, I'm guessing this could be done by specifying "print_progress=False" as a kwarg when we call "solve". Not sure about scipy.

Should be fixed in the last commit. We were looking into to ways to solve this since we incorporated it (see numericalalgorithmsgroup/pybobyqa#10) but they were not using the logging module, so it wasn't possible until the last version they have published.

Now prints nothing unless debug: True (unfortunately they don't provide an intermediate level for reporting progress).

It works great, thanks!
