Logging bug in GUI in debug mode

[RalfG]

In the GUI, in debug mode, keras tries to write its progress bar, but fails. In non-debug mode, this is not an issue, most likely due to the redirect to os.devnull. Perhaps in the GUI, we should always do this?

Stack trace:

'NoneType' object has no attribute 'write'
