I’ll write a new thread for this latest issue, here: Hitting a weird error to do with RNGs in Scan in a custom function inside a Potential

  File "/Users/jon/miniforge/envs/oreum_lab2/lib/python3.10/site-packages/pymc/pytensorf.py", line 1088, in find_default_update
    raise ValueError(
ValueError: No update found for at least one RNG used in Scan Op Scan{scan_fn, while_loop=False, inplace=none}.
You can use `pytensorf.collect_default_updates` inside the Scan function to return updates automatically.
