@fsaad thanks for pointing me to those docs. Encountered failure at the second step. Looks like I need to enable some different channels (e.g. we need seaborn=0.7 and current channels don’t list anything earlier than 0.8)

@fsaad made some more progress. So it seems the problematic packages (i.e., the packages that conda has a difficult time with) are bayeslite and loom. The others I was able to install via conda in a very straightforward manner (after including the extra channels you pointed to).

After that, I was able to install bayeslite by building from source via setup.py. I suspect a similar process might work for loom as well.

I am new to conda, but it seems the dependency tracking for bayeslite conda package is messed up. Hope this helps.
