I have been having the below error trying to reload Pyxll since updating my Anaconda version to 5.0.1 Python 2.7 64.
ERROR : Not reloading dependency ipywidgets.widgets because of previous failure
to reload ipywidgets.widgets.interaction
2018-07-30 13:57:52,440 - ERROR : Error reloading
'ipywidgets.widgets.interaction'
Add the following to pyxll.cfg config:
deep_reload_exclude =
ipywidgets
traitlets
Which excludes troublesome modules. Thanks to Pyxll support for soln.
