Problems running in a thread on Linux/Mac (with solution) #20
Description
Just adding this note in case anyone else runs into this. I tried to run this code in a thread on Mac/Linux and was met with a bus error, no stack trace. Really not fun to debug. You can fix this with:
# Need this setting because of this issue:
# https://github.com/numpy/numpy/issues/654
os.environ["OPENBLAS_NUM_THREADS"] = "1"
Make sure that its called before anything else, well maybe mostly Numpy. This is due to this line in utils.py:
inv_A = np.linalg.inv(A) # we assume A invertible!
Also, I do have this codebase running on Mac M1 if anyone has use, happy to post a PR.
