Tutorial m.run fails inside notebook, but works in terminal

[michaelaye]

Following tutorials like here:
http://docs.hyperion-rt.org/en/stable/tutorials/tutorial_images.html
there is usually a

m.run('...')

following the

m.write('....rtin')

Trying to execute this in a current Jupyter notebook on Python 3.5 it reliably fails:

while I can start the model in the terminal using the standard

hyperion -m 4 ...rtin ...rtout

approach.

Was wondering if you might have an idea why it fails in the notebook?

My versions are all up to date with what's available today on conda-forge.
E.g. notebook 5.0.0 py35_0, hyperion 0.9.9
