I am working on an old project and I am trying to build a conda environment based on a config file. It used to work well few months ago but now I run into some issues, here is my file
name: proj1
channels:
  - defaults
dependencies:
  - python=3.7
  - pip
  - pip:
    - matplotlib
    - tensorflow
    - tensorflow-probability
Now if I run conda env create -f conda_env.yml I get the error :
Collecting package metadata (repodata.json): done
Solving environment: failed
ResolvePackageNotFound: 
  - python=3.7
Why is that ? I've set up many conda environments this way but it is the first time I run into this
Thanks a lot
