osx-arm64 version of qutip?

[dooleysh]

Hi. I've been trying to install qutip on a new Mac with the arm64 processor (with the command conda install -c conda-forge qutip). However, it seems that qutip is not available on any of my conda channels. Do you know if there are any plans to make qutip available on an osx-arm64 channel? Thanks.

My error message:

conda install -c conda-forge qutip

I think both conda and cibuildwheel (how we build for pip) both support building on M1 Mac now, so we probably ought to be able to do this. Would you mind opening an issue on qutip/qutip as well? It'll get a few more eyes that way (I don't have as much time to sort out the build process for qutip any more...).

Ping for @hodgestar and whoever may kindly help keep an eye on this.

I'll try address then when we do the rebuild for Python 3.10, but that has to wait for qutip/qutip#1735 or similar to be merged and for QuTiP 4.6.3 to be released (hopefully in the next week or so).

[hodgestar]

QuTiP 4.6.3 has been released, so now we are just waiting for conda-forge builds to work again so that we can finish merging #74. We should check whether that builds for the M1.

[hodgestar]

#74 didn't automatically add builds for the M1, but I will try get the robots to open a PR for the M1 builds shortly..

[hodgestar]

I've merged #76 so hopefully M1 builds should appear in a couple of hours and we can try them out!

It looks like the OS X ARM64 builds have succeeded. I'm going to close this issue for now. Please give them a try and let me know how it goes.
