Problem installing dmlab2d for M2 arm64 #122

Closed jonathan-cook235 closed 1 year ago

The README states that there is no appropriate wheel for the Apple M1/M2 chipset. It provides an example bash script for installing and setting up the wheel, but this results in an error when trying to import dmlab2d_pybind.so, saying that the version installed was still 'x86_64' rather than 'arm64'. I'm unsure what to change about the bash script to get the right version installed.

I can't help I'm afraid: I think this is an issue with your setup. The bash script works fine on my arm64 mac, and in our tests. My guess is that you have the x86_64 version of Bazel and not the arm64 version (or XCode or some other part of your toolchain).

Here's what my mac says:

$ bazel version
