Installation issue on 3.10.6 on macOS

Hi Piyush!

It sounds like a segyio issue, it is trying to build it from the source. Kinda surprised it is not getting a wheel.

What CPU architecture are you on? Maybe segyio doesn't have wheels for that.

I had a similar issue with OS X ARM64 (M1) architecture and opened this issue equinor/segyio#534

EDIT: Looking at it you are on OS X ARM64. Yes that is expected. Unfortunately won't be able to fix until the segyio team provides an OS X ARM64 build. In the meantime you can install the build dependencies for segyio manually.

Another solution is to run the x86_64 version of Python with Rosetta 2 emulator. That works fine, but it will probably run a little slower.

Thanks Altay. Indeed I am on an M2 Air. Hoping that segyio fixes this soon. Will keep my fingers crossed.

No problem, closing the issue for now since it is resolved!

Thanks @pikumar

I had the same problem on M1 Max and created an environment using conda and set the architecture to x86_64 using the following lines of code.

CONDA_SUBDIR=osx-64 conda create -n myenv_x86 python=3.9
conda activate myenv_x86
conda config --env --set subdir osx-64

@AmirMardan, thanks for the workaround. I guess that this runs the x86_64 version using Rosetta 2. While it may work, it probably won't perform as fast as the native :)

The last time I checked on my Mac, segyio was compiling on ARM64 ok; hence mdio should work ok as well. Are you seeing a similar issue with the latest segyio ?

[AmirMardan]

Yes, I had the same problem and I had to create another environment with osx-64 to make it work.
