conda and pycapnp

Question

Hi there, I keep running into errors installing Syft and I'm not sure how to proceed.

Further Information

I have followed the documentation and receive an error when attempting to run pip install -U syft --pre . It keeps exiting the install, and I'm really not sure what to do, would appreciate any help. I've tried installing different versions as well, (as recommended by some friends) but no luck.

Screenshots

System Information

• macOS Ventura
• Version 13.0.1
• conda 23.10.0

I think there seems to be some issue with conda and pycapnp, I will get the team to investigate this.

can you try installing after lowering the version of cython? for instance - pip install cython==0.29.36

I had the same issue. I used python 3.10.14 and the error is gone.

@Smartappli we will bump the version on pypi asap but this does seem like a conda package management issue. Compilation of pycapnp is non trivial.
