conda install: incompatible with existing python 3.8 #487
Description
I assume this is a "known" issue, but I'm curious what the recommendation is. When creating newer conda environments, the default python installation is going to be 3.8 (or apparently 3.9 at this point), but our BrainIAK specification is pinned at python <3.8... This means that the conda installation instructions on the website will only work if BrainIAK is one of the first things you install in the conda environment—right? (This has happened to me a couple times where I start building an environment with other generic python packages, then get to BrainIAK and am stuck.) Why are we pinned at <3.8, and what's the recommended fix here? Is the recommendation to just roll back the python version in my conda environment to please BrainIAK? Unless we're planning to unpin this soon, we might want to explicitly mention this on the installation page.
$ conda install -c brainiak -c defaults -c conda-forge brainiak

hi there. Having the exact same issue -- so brainiak is not compatible with python 3.8? How can I work around this? This may have been stated in the response above but if so, it went over my not-so-techy brain.
Thanks,
Sid
