-# Some notes as to why we are using pip AND mamba:
-# - ntlk_data cannot currently be installed with mamba (while we have python 3.8).
-# - datascience cannot be installed with mamba
-# - The latest version of pytables, a dependency, only supports python 3.9 and up.
-# - The latest compatible version (3.6.1) seems to be broken.
-# - pytables is necessary, otherwise nltk will install out-of-date package
-# - pytables on conda == tables on pip (???)
-# - without pytables explicitly defined, version 3.6 will be installed (which seems to be broken when testing the import)
