Upgrade conda package to use Python 3.8
The current version of the Conda package has packages pinned to particular versions. This seems to make impossible to use versions of Python higher than 3.6. I think that this is one of the reasons blocking us from using recent versions of Pytorch, for instance.
When using iota2 as a library for building other processing chains, this is still more critical, since we may need other dependencies which need recent versions of Python.
I understand that the version pinning was done to try to overcome some dependency hell in the conda package. I suggest starting from the current conda env and trying to upgrade Python to 3.8 and see what packages are blocking the upgrade and work from there.
