A bug

[jiwei08]

There is a bug when creating output_uz... in Farneback3D.calculate_flow using the default total_vol (-1,-1,-1).

Hi @jiwei08, could you provide more details about the problem you are encountering? If you are able to provide an example and steps to reproduce it, that would be very helpful. Thank you.

Emmmm, output_vx is created in line 87 in opticalflow3D.py with the shape of total_vol. But the default of total_vol is (-1,-1,-1) which would cause a bug when creating a numpy.ndarray using (-1,-1,-1).

I have just tried this code and sorry for not providing a MFE.

Thanks for pointing out this issue. An update to the python package will be pushed shortly.

In the meantime, please either set total_vol to None or specify it explicitly (e.g. (100,100,100)).
