seems to fail on an M1 Mac.

Stevan!

Switch to linux or windows

Not a Mac user, but try installing Homebrew through a Rosetta terminal, and then install x86-64 Python through that?

Also, you should use Python 3.9. Opspy seems to have dependency issues on 3.10 (i.e. the maintainers have locked the requires to 3.9).

Hi, fmckenna
Did you solve this problem? Recently, I encounter the same problem as you. Do you have any suggestions for this problem?

I met same issue.

*****/site-packages/openseespymac/opensees.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')),

Same here.

Same issue with the M2 pro chipset. I wanted to try helping to a friend. But I can't even import the library. lol.

[serkanhasanoglu]

The problem was solved in my case after applying the steps below.

1. Install Rosetta
2. Create a Rosetta terminal
3. Install X86 homebrew in the Rosetta terminal
4. Create an alias for the X86 homebrew in /usr/local/bin/brew
5. Use the X86 brew to install X86 python (ends up /usr/local/bin/python3)
6. pip install

You can solve this also via Miniconda, which then still allows using Spyder as IDE as normal. Please see:
