Cannot import JAX using M1 Mac

Hi!

I have just installed version 4 of PyMC on an Apple m1 device and I followed these instructions.

However, when I try to import jax, I get the following error:

RuntimeError: This version of jaxlib was built using AVX instructions, which your CPU and/or operating system do not support. You may be able work around this issue by building jaxlib from source.

How can I fix this?

P.S. I have recently started working with PyMC and I am learning a lot. I cannot wait to use this new version. Thank you for your hard work!

I running into this issue as well. Did you figure it out eventually?

Note that the “official” installation instructions can be found here. What version of jax do you have installed and how was it installed?

4

Installed jax and jaxlib == 0.3.0 using pip install.

I have M1, and I don’t have this message. I used:

python3 -m pip install jax jaxlib numpyro

Good to hear! What versions of jax, jaxlib, numpyro and python are you on?

7 
>>> print(watermark(packages="jax,jaxlib,numpyro"))
jax    : 0.3.23
jaxlib : 0.3.22
numpyro: 0.10.1

# no messages
>>> import jaxlib
>>> import jax

Python is 3.10.8

Finally got it to work! I re-installed mini forge, this time not using homebrew. (Ad modem Mac M1 Monterey Installing Miniforge and Anaconda/Miniconda Side-by-Side - YouTube).

Hang in there, j_catulo, the sweet sweet performance increase is worth it.

Ah yes. I definitely suggest using the recommended installation routine at all time, regardless of platform. Glad it worked out for you!

I used homebrew in my case - so, maybe there was something else
