So I went to the Package Manager after cloning and activating the new python environment.
When I perform a search with dltsolutions as per the instructions provided it is blank. Any idea why it would not work as per the instructions?
I went to the Frequently Asked Questions of why the dltsolutions would not work after cloning the environment and Refresh fixed the issue. (An auto-refresh after cloning the python environment would be super helpful here)
Another note is that I was not using the latest version of Pro 3.1 (3.0.3 actually) and the default python version failed so I went to the next lower version and it worked.
conda install with the specific version you need works or download and install from the actual distribution site
the 4th on the list
