Answer 1

You're using Heroku's documentation to deploy with the Python buildpack which doesn't support a Conda runtime. The Heroku recommended approach is to use Docker (example here) to deploy a Conda runtime to Heroku.

Another option would be to simply use a Conda buildpack instead of the Docker image.
