I am trying to install the gym package in conda for Linux. I have created a virtual environment and am using the following command to try and install:
(gym_env) [user]$ conda install --name gym_env -c hcc gym
But am getting the following issue:
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

I am finding it difficult to interpret this error so am not sure where to go from here to try and fix it.
I also tried installing the package at the same time as creating the environemt but there was the same issue.
Python version - 3.6.9 conda version - 4.7.12
Hopefully someone can help me!
While the hcc channel hosts the gym package, it has a requirement of pyglet which is not available on hcc or defaults. Try also including the conda-forge channel as well:
conda create -n gym_env -c hcc -c conda-forge python=3.6 gym
Note, that when creating an env for a specialized purpose, it is generally recommended to include the key packages at creation.
