cannot use environment.yaml to install conda env

Hello, I got the following message when installing conda with environment.yaml:

Pip subprocess error:
ERROR: Ignored the following versions that require a different python version: 1.6.2 Requires-Python >=3.7,<3.10; 1.6.3 Requires-Python >=3.7,<3.10; 1.7.0 Requires-Python >=3.7,<3.10; 1.7.1 Requires-Python >=3.7,<3.10

Try adding --extra-index-url https://download.pytorch.org/whl/cu116 to your environment.yml file like this:

...
  - zstandard=0.19.0=py310h5eee18b_0
  - pip:
    - --extra-index-url https://download.pytorch.org/whl/cu116
    - absl-py==1.2.0
...

You can run conda env update --file environment.yml to re-download the dependencies in a conda environment you've already created.

I had the exact same issue, and this seemed to fix it for me. I'm basing what I did off of these two webpages:

• https://discuss.pytorch.org/t/no-matching-distribution-found-for-torch-1-13-1-cu117/174577/8
• https://conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#updating-an-environment

Thanks Peter for you solution of solving the conda environment. Did you run the command pip install -r requirements.txt and do we need to run it? Thanks.
