M1 Mac Support #364

Closed 8one6 closed 1 year ago

8one6 commented 2 years ago

Hi, is there currently any support at all for M1 mac? If not, is there any plan to add that support?

conda might support it already.

Thanks for that nudge. I found something in a previous Issue note about suggesting to install httpstan (from source). That worked for me! I'd suggest maybe adding something to the install instructions saying that M1 mac installs (on the ARM architecture) work fine with this workaround? Very disheartening to hear it wouldn't be possible (based on the official docs) but very exciting to see it actually works! Also, worth mentioning the ASyncio workaround for Jupyter notebooks in the official docs?

M1 users should be fine if they build from source right now. They do need to follow the instructions in the docs.

We would very much like to build wheels for other platforms (M1, risc-v, etc) or, at least, allow automatic building from source (i.e., a source distribution that pip can work with).

We could do this today with scikit-build if an experienced cmake user would volunteer to make the changes here needed for httpstan to use cmake (rather than make).

At the very least, maybe point that out in the docs? That installing from source should work on M1? Seeing that your platform is unsupported is a real downer!

Is there instructions on how to build from source? I'm facing the issue on an M1 Mac

First install httpstan from source, https://httpstan.readthedocs.io/en/latest/installation.html

Then you can pip install pystan (which is pure Python).

I did the install from source but I can't seem to import?

riddell-stan commented 1 year ago

Let's take this to the forum: https://discourse.mc-stan.org/ That's the right place for installation issues.

I'm going to close this for now since it's not really a bug and M1 support already exists. M1 wheels will emerge eventually -- no ETA, alas.
