Thank you @ptrblck for pointing out this issue!
Hello @Nazila-H,
As a small disclaimer, you are using syft_0.2.X, which currently is not under active development. If you want to get familiar with the syft ecosystem I would recommend:

Joining the OpenMined slack and asking questions there, you will really fast responses.
Try the new 0.3.0 version.

If 0.2.X is a hard requirement, please create an issue here:
PySyft 6
And add the 0.2.X tag, the community/people that are still working to fix issues on 0.2.X will help you as soon as possible.
Thank you,
Tudor Cebere
