| # Auto activate conda environments | |
| # - If an `environment.yml` or `.venv` file is in the current directory, | |
| # the environment specified by that file is activated | |
| # - `environment.yml` files are parsed | |
| # - `.venv` files must contain just the name of the environment | |
| # - If no such files are present and no environment is already activated, then | |
| # we try to activate an environment with the same name as the current directory | |
| # - Assumes that the conda installation is at $HOME/miniconda3 | |
