Issue installing on ARM 64 MacOS 151.1

[doonhammer]

Describe the bug

Following the install instructions for Anaconda and Apple Silicon Mac mini M2 I see the following error with the
conda env create
step. I am getting the following error dump

Channels:
 - aihabitat
 - pytorch
 - pyg
 - defaults
 - conda-forge
Platform: osx-arm64
Collecting package metadata (repodata.json): done
Solving environment: failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - nothing provides requested aihabitat::habitat-sim =0.2.2*
  - nothing provides requested mkl <2022
  - nothing provides blas * mkl needed by pytorch-1.11.0.arm64-py3.8_0

Could not solve for environment specs
The following packages are incompatible
├─ habitat-sim 0.2.2*  does not exist (perhaps a typo or a missing channel);
├─ mkl <2022  does not exist (perhaps a typo or a missing channel);
└─ pytorch 1.11.0*  is not installable because it requires
   └─ blas * mkl, which does not exist (perhaps a missing channel).

I am running the following Python version

Python 3.12.7

Hi @doonhammer, I'm sorry that the install instructions are not working.

On Apple's ARM 64, the Anaconda instructions require to specify the environment file explicitly:

conda env create -f environment_arm64.yml

Is the above command the one that generated the error?

If you still get the same error even when specifying -f environment_arm64.yml, this may be a similar problem described in #81. There, the solution seemed to be to use the Miniconda setup instructions (if you're using zsh shell):

conda env create -f environment_arm64.yml --subdir=osx-64
conda init zsh
conda activate tbp.monty
conda config --env --set subdir osx-64

Or if you're using bash or some other shell:

conda env create -f environment_arm64.yml --subdir=osx-64
conda init
conda activate tbp.monty
conda config --env --set subdir osx-64

Adding --subdir=osx-64 did the trick with Anaconda install. Install succeeded and all tests passed. Thanks for the help
