Trouble Setting up Chemvae

[shmurthy7002]

I used conda to create the environment and then selected the "chemvae" interpreter in vscode. When I try to run the first cell of the given example script (all of the imports), I run into the error below, I tried removing and adding the environment again, I also tried using pycharm instead of vscode, and neither fixed the problem. I am new to using conda so please bear with me, thanks in advance.
