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.

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.
