New environment.yml generation is buggy

[trevorcampbell]

Misses tidyclust and ISLR etc (because it's not installed using mamba)

This may need to be manually updated for now...

(same in py repo)

[trevorcampbell]

One issue is that tidyclust is not yet available on conda forge. See tidymodels/tidyclust#167

[trevorcampbell]

I wonder if we should ditch the environment.yml file and just have a shell script so that we can do whatever we want and not worry about future compatibility...

If we do this, we should keep the environment file anyway (or maybe we can somehow force conda to print a warning message pointing people to our repo where we have our new shell script....hmmm)

[trevorcampbell]

In order to get conda to print a message when trying to update the environment, you can do something like the following

(note the two dots are important to get conda to fail quickly, otherwise it takes forever searching for a bogus package name)

name: base
dependencies:
  - ". . hello this is a message"

If you run conda env update environment.yml on that file, you will see

(base) jovyan@5d0fe92f9fae:~$ conda env update --file environment.yml 

CondaValueError: invalid package specification: . . hello this is a message
