Misattribution of import errors

[bradezard131]

A failure to import IPython and matplotlib is falsely attributed to a a failure to import ipywidgets. Matplotlib is not a requirement for fastprogress and so this is an easy error to cause but requires source-code delving to debug.

fastprogress/fastprogress/fastprogress.py

Lines 97 to 103 in e7d108f

	if IN_NOTEBOOK:
	try:
	from IPython.display import clear_output, display, HTML
	import matplotlib.pyplot as plt
	except:
	warn("Couldn't import ipywidgets properly, progress bar will use console behavior")
	IN_NOTEBOOK = False

Just ran into this as well. In my case I was missing matplotlib. A simple fix would be to reword the error message. Nicer would be to enable as much functionality as possible without matplotlib if it doesn't exist. Not sure how much work that would need though.
