I bit the bullet and got one. I used pip to install pymc (contra the instructions). My simple “hello world” model samples quite briskly, but a more complicated model is raising exceptions when I try to sample in parallel (serial sampling works). Identical code worked, in parallel, on my Intel-based MacBook.
I’m going to try installing from conda and/or creating a minimal working example.
Nice, let me know how it goes - keen to move on from windows - Weird coincidence, just trying out your example of a statespace model in pymc aha, which ironically doesn’t work in parallel for on my build aha.
I just installed pymc 5.0.1 using mambaforge and my model sampled in parallel successfully. It took half the time as on my Intel-based MacBook Pro and with infinitely less fan action.

good stuff!
Thank you very much. The installation worked flawlessly, but quite a lot tests in the test suite FAIL. Any ideas if this ok in an M1?
======================================================= 55 failed, 25 passed, 1 xfailed, 2 warnings, 6 errors in 47.21s =======================================================
How did the tests fail? There are some test-only dependencies that must be installed separately from the main PyMC installation.
Overnight windows updates and turned off/on and it seems to sample in parallel now. peculiar aha
Hi. Thanks for the reply. I have installed the required dependencies and run
pytest -v pymc/tests/test_model.py
A few test pass, but many don’t.
Running pymc 5.0.1 with pytensor 2.8.11 (the only dependency I could not correctly install).
The installed packages are in the list below. Please let me know what other information could I provide.

Can you share one of the tracebacks of the failing tests?
Here is the full output for the entire suite. I’ve gone through it to see if I could spot something, but I am afraid I’m not proficient enough. Certainly pytensor and the link module seem to be causing some of the issues.
Please, let me know if I can provide anything more useful than this.
And thanks a lot for your help.
pymc_tests.txt (1.2 MB)
UPDATE: following this post, I decided to give the test a try preappending /usr/bin to my PATH, and magically now only two tests fail! It seems that the system compilers are required on my M1. Is this reasonable?

Yes that’s reasonable
Hi,
I have to admit that I am not a professional programmer. Still I would like to use pymc as a data analysis tool!
I have tried to use miniforg environments to run pymc scripts but did not succeed.
Can you maybe make a more detailed tutorial how to install and make pymc run on M1 chip macs? That would be much appreciated by me and certainly others!!!
Very Best!
I installed pymc this morning on my 16" M1 Mac, latest gen.
Make a virtual environment using either conda or venv. Run pip install pymc. That’s it.
Here’s my terminal code should you want to copy it:
mkdir pymc-test # make a folder to contain our virtual environment
cd pymc-test/ # enter it
python -m venv .venv # make a python virtual environment to keep our packages clean
source .venv/bin/activate # activate this environment so that "python" points to that environment
pip install pymc # install pymc
python -c 'import pymc' # this should run without any output
If you also want e.g. jupyter notebook or other packages, you would add them during the “pip install” section. To use pymc in vscode’s notebook, you would do;
pip install pymc ipykernel

Hi. Same thing, got an M2 and ran into all kinds of problems. You seemed to have the only workable solution so far (for a beginer like me), but I can’t make it work either, some dependencies still break.
Are you aware of a more structured solution? Or is the solution so obvious that no one evert posts is back?
Thanks!
These days I am using conda to install pymc, not pip, because I’ve been encountering slowness with the latter. I’m pretty sure I followed the instructions, and just did conda install pymc. What errors do you get when going this route?

Can you give us some specifics on the kind of errors you experienced?
Hi. I’ve started too many threads on this - I’ve already replied here: Installation issues v5.9 macOS - #11 by salvador_v
But to your question, the installation works fine, but all breaks when I try to install theano. I’ll paste it here for reference too:
I’ll appreciate any insight on this. Thanks!
Theano is not maintained and is not compatible with recent python releases, as the error message shows. Why are you installing it? PyMC doesn’t use it.
Out of sheer newbishness, really. I’ve just started working on probabilistic programing using Martin et al ‘Bayesian Modeling and Computation in Python’, which is based on PyMC 3, but their env is not compatible with my Mac. Now I’m starting over with PyMC 5 and then will go back to the book.
