Re: [Ifeffit] larch warning that I don't understand

[Shoaib]

I don’t see any of this warning message after I installed Python 3.6.4 through 
Miniconda (Anaconda, Inc.) and installed Larch in Conda, I installed opencl 
package as well. Though I received this warning message in Python 2.7.

Regards,
/Shoaib

Would it be helpful, then, to do something like this in some appropriate place?

   import warnings
   warnings.filterwarnings("ignore",".*No handlers could be found*")

I see the first one on lots of machines.   It's an obnoxious warning
message from pyFAI about functionality we don't actually use.

I don't see the second one very often.  I suspect that is because it really
means "could not import one of the Python-Qt variations", which the pyFAI
GUI probably uses.
Again, we don't actually need this functionality in Larch, so it is an
obnoxious warning message.

Both warnings are harmless.

[Ifeffit] larch warning that I don't understand

[Ravel, Bruce]

Matt,

When Larch starts, what is meant by warnings like this:

  No handlers could be found for logger "pyFAI.opencl.common"

or 

  No handlers could be found for logger "pyFAI.gui.matplotlib"

The first one went away by installing python's opencl interface -- a rather 
sizable prerequisite! I haven't figured out how to make the second one happy.

Thanks,
B
