Hey @0it 👋

Thanks for your contribution! It looks like you're linking the linux binary to your local machine — what was wrong with the original binary? Were you getting any errors that you can share?

@nickzuber Your release on pypi is not bundling the stockfish binaries and therefore they can't be found. This PR is not the best fix as it expects stockfish installed in the system.

I have downloaded the file manually and put on the expected location, but would be better if you just bundle the binaries or download them from github during install
