requirements.txt is not a valid Python requirements file

[dmhowcroft]

Expected behavior: running pip install -r requirements.txt successfully installs Python libraries to reproduce the code.

Observed behavior: errors due to differences between conda requirements files and Python requirements files (see this question on StackOverflow).

My understanding of the problem / what I have tried: Regex find and replace to swap the first = for == and delete the trailing, conda-specific =... results in a more valid requirements file, however this still includes a lot of additional libraries relevant to conda but not to pip, like blas, libcxx, libedit, etc, which would normally have to be installed separately depending on the distribution / environment.

Suggested fix: Create a standard Python requirements.txt file by running:

conda activate <env>
conda install pip
pip freeze > requirements.txt

and adding that requirements.txt to the repo (perhaps renaming the current one to conda-requirements.txt.

I don't use conda, so I cannot do this myself and submit a PR.
