Running into a Segmentation Fault with training script

[steven-struglia]

Hey there!

I wanted to try out this library to see what STAN could offer over a Pyro + Jax implementation I've been using, but am running into a segmentation fault when running the training script:

(light_env) jupyter@steven-cuda-test:~/BayesianMMM/bayesian_mmm$ python3 train.py
DIAGNOSTIC(S) FROM PARSER:
Info: assignment operator <- deprecated in the Stan language; use = instead.
Info: assignment operator <- deprecated in the Stan language; use = instead.

INFO:pystan:COMPILING THE C++ CODE FOR MODEL anon_model_bd553489cb51804a3a661777a8e7f5aa NOW.
Segmentation fault

What should I look into in order to help diagnose and fix this seg fault? Is there anything in the configuration yaml that could cause this to happen?
