cannot install genomepy with conda on arm64 Mac OS X

[ctb]

Hello! genomepy looks super interesting! I was trying to install it with conda and got:

% mamba create -y -n genomepy genomepy
Looking for: ['genomepy']

bioconda/osx-arm64                                            No change
conda-forge/osx-arm64                              @ 264.6kB/s 13.1s
bioconda/noarch                                    @ 263.9kB/s 14.2s
conda-forge/noarch                                 @ 235.6kB/s 40.2s
Encountered problems while solving:
  - nothing provides bucketcache >=0.12.1 needed by genomepy-0.10.0-pyhdfd78af_0

I was able to run the same command on linux and it worked, so it looks like maybe an arm64 limitation?

I tried using pip install genomepy in an empy python3.9 conda environment and it successfully found all of the dependencies, but it was going to compile a bunch of stuff (again, for arm64) so I decided not to follow through ;). So this may just be a conda problem above!

Hi @ctb, thanks for reporting this. As far as I know bioconda does not support arm64 builds yet (while conda-forge does). This indeed means that many of the dependencies will not be available. OS X is always a bit difficult for us, as we don't use the hardware ourselves. I guess most of the Python dependencies will be fine, however, I don't know if the UCSC tools (gffToGenePed and the like) are available for arm64.
I guess this is all to say that I hope arm64 will be supported by bioconda soon :)
