Error while trying to import pysyft in lesson 1 Duet Basics (Foundations course)

[cbs-rschreijen]

Hi,

I setup a virtual environment (tried both conda and venv), activated it and installed pip requirements per course instruction. When running the notebooks for the Duet Basics demo I get an error at the first statement in both notebooks while loading the pysyft library (same error). I am running on macOS 11.1 Big Sur.

Hi there! Turns out the version of Syft on PyPI is a bit old. Can you install Syft with this:

pip install git+https://github.com/OpenMined/PySyft@dev#egg=syft

You might need to uninstall Syft first, pip uninstall syft.

This should work, let me know if it doesn't.

[RushnaiwalaTaki]

Yess. Its fixes. Great, Thanks

[lepangdan]

It doesn't work to me! please help

[Merna-Atef]

It doesn't work for me either. I have tried all the steps.

[YasMinSdt]

It doesn't work to me! please help

Have you found a solution to this?

@YasMinSdt
Try installing jaxlib==0.3.14 first if your using it in windows

I'm also in the same point where u were,new to pysyft.Hope this would help
