hi @sb1000,
Thanks for the details and sorry you're having issues.
Ah - I suspect this is the problem. Whether you install with the wheel file or via pypi, by default, it'll try to install dependencies automatically, trying to install them via pypi. Since you're behind a proxy, any of those packages that aren't part of your miniconda, likely won't be installed correctly. I suspect if you went through your logs when you try to install, you may find some of your dependencies aren't correctly installed.
Can you try to follow these instructions (see instructions on installing w/o the internet), installing each dependency first, then installing your wheel file with --no-deps?
