[BUG] <'ray-default' channel is causing issues >

[CodelyUnicorn]

Describe the bug It seems that the 'ray-default' channel is causing issues during the environment creation process. The error indicates that the package metadata for 'ray-default' is not accessible, resulting in a 404 error.

To Reproduce Encountered issues while attempting to set up the GenomeNLP environment using Miniconda and Mamba. Below, I have outlined the steps I followed, the errors encountered, and the attempted solutions:

Step 1: Miniconda Installation

• Downloaded the Miniconda installer for macOS ARM64 using the command: curl -O https://repo.anaconda.com/miniconda/Miniconda3-py39_23.3.1-0-MacOSX-arm64.sh
• Executed the installer script using: bash Miniconda3-py39_23.3.1-0-MacOSX-arm64.sh
• Reloaded the shell environment.

Step 2: Mamba Installation

• Attempted to install Mamba using the command: conda install mamba -n base -c conda-forge

Here I encountered the following error due to an inaccessible channel ray-default: HTTP 404 NOT FOUND for channel ray-default Attempted Solution for the above error :

• Checked the current Conda configuration channels using: conda config --show channels
• Identified the presence of the problematic channel 'ray-default'.
• Removed the 'ray-default' channel from the Conda configuration using the command: conda config --remove channels ray-default
• Retried installing Mamba using the same command: conda install mamba -n base -c conda-forge

This time Mamba installation succeeded.

Step 3: Creating GenomeNLP Environment

• Attempted to create the GenomeNLP environment using Mamba: mamba create -n genomenlp -c tyronechen -c conda-forge genomenlp -y
• Here again I encountered a dependency issue related to the 'ray-default' channel: The error message says 'genomenlp is not installable because it requires ray-default 1.13.0, which does not exist.'

I Attempted Solution:

• Added the 'ray-default' channel back to the Conda configuration using: conda config --append channels ray-default
• Retried creating the GenomeNLP environment. Faced another error due to the 'ray-default' channel: Multi-download failed. Reason: Transfer finalized, status: 404 [https://conda.anaconda.org/ray-default/noarch/repodata.json] Error message shows as "An unexpected error has occurred. Conda has prepared the above report. If you suspect this error is being caused by a malfunctioning plugin, consider using the --no-plugins option to turn off plugins. Example: conda --no-plugins install Alternatively, you can set the CONDA_NO_PLUGINS environment variable on the command line to run the command without plugins enabled. Example: CONDA_NO_PLUGINS=true conda install "

Then again I tried manually installing 'ray-default' with the command: pip install ray-default==1.13.0 Again faced error which says:
ERROR: Could not find a version that satisfies the requirement ray-default==1.13.0 (from versions: none) ERROR: No matching distribution found for ray-default==1.13.0

Thanks @CodelyUnicorn for your comprehensive and detailed bug report!

Unfortunately, this package will only work on linux platforms and is untested with Mac OS. I was able to replicate your issue on a Mac. The supported platform tag in the repository is misleading and a note was added in the README accordingly.

If you have any other questions, please do not hesitate to reach out.
