I'm trying to get stockfish for python working but I am running into issues. This is my code so far.

from stockfish import Stockfish
stockfish = Stockfish('/Users/Me/opt/anaconda3/lib/python3.9/site-packages/stockfish/models.py')

This returns a OSError: [Errno 8] Exec format error: '/Users/Me/opt/anaconda3/lib/python3.9/site-packages/stockfish/models.py'

This is where I downloaded the package from: https://pypi.org/project/stockfish/. After this, as I have a Mac, I downloaded it through homebrew and my installation has a path /opt/homebrew/Cellar/stockfish/15, but this also does not work.

Download an appropriate stockfish binary at https://stockfishchess.org/download/.

Remember where it is and use that location and engine filename.

stockfish = Stockfish('/engine_path/engine_filename')

    I realized my mistake. The file was inside /opt/homebrew/Cellar/stockfish/15 but I had to do ⌘+Shift+G in order to actually find the stockfish file inside. The final path ended up being /opt/homebrew/Cellar/stockfish/15/bin/stockfish

I think the path that you give to the Stockfish constructor is wrong.

According to this page https://pypi.org/project/stockfish/ you should rather give the path to where you installed your engine, so probably /opt/homebrew/Cellar/stockfish/15 , not some python file in the stockfish package.
