Pysyft: module 'torch._C' has no attribute 'Function' - error when importing syft

[s-marta]

Describe the bug
I'm having a lot of troubles installing pysyft on Ubuntu 18.04. I cloned the repo and tried to install it according to those instructions:
Install Python 3.6 or higher Install PyTorch 1.3 Clone PySyft (git clone https://github.com/OpenMined/PySyft.git) cd PySyft pip install -r pip-dep/requirements.txt pip install -r pip-dep/requirements_udacity.txt python setup.py install udacity python setup.py test
I managed to install all requirements but then got an error on the second to last step (python setup.py install udacity) saying error: invalid command 'udacity'

I then tried to install pysyft using pip install syft and it was successful but when I'm trying to import it I get the following error (AttributeError: module 'torch._C' has no attribute 'Function')

What should I do to be able to use pysyft?

I think we need to spin a new pysyft version? @karlhigley

[karlhigley]

@s-marta Just published a new release that we think should address this issue. Could you give it a try and let us know if that resolves your issue?

[s-marta]

@karlhigley I updated and it seems to be working! I managed to import it and basics from the first tutorial seem to be working as well. Many thanks for such quick help.

Thanks for letting us know!
