- python=3.7

Hello, I just wanted to draw your attention to the fact that conda is having difficulty installing python versions less than 3.8.
Is it possible to upgrade to python 3.8 and making sure dependencies are also upgraded and working? thanks.

Hi, so sorry I didn't see this for a while! I'll have to take a look into this, when I last set the dependency versions Python 3.7 was a required set by Spark and the container images the library uses for Spark workers, but these requirements may have changed. Feel free to play around with changing the version to 3.8, I'll also be working on this library again soon for another project so can help out. I am also curious what are the difficulties with installing Python versions less than 3.8? I see that LTS for 3.7 ends in 4 months so I should probably work on upgrading anyway.
