Hi @sunbc0120 thanks for reporting.

Installation instructions work for me (M1 Pro, macOS 12.5.1). I have a more recent version of Python but that shouldn't be the issue, did you try from a clean env? Also, can you try installing only mmh3 in a clean env to see if that's the problem?

Hi, thanks for the response! It turns out pip installs x86_64.

I had to pip uninstall mmh3 then conda install mmh3, which picks it up from channel pkgs/main/osx-arm64.

Same thing happens with lxml in the next step.

Though later would run into problem described here: bastibe/python-soundfile#310, I would close this issue for now.
