It doesn't say what the problem is. These Python scripts can be executed/loaded fine as standalone files.

It's not a bug. If you don't have torchani installed, ani2x.py won't run - simply a warning. Similar with openbabel and gaff / mmff94 / uff and xtb-python and the gfn* scripts.

Since some people seem put off by the messages, we'll switch them to being separate plugin downloads.

[yurivict]

Is it this torchani?

[ghutchis]

Yes, exactly. It's not required for avogadro though.

[yurivict]

Ok, thanks.

[ghutchis]

Of course - feedback / bug reports always appreciated!

[yurivict]

IMO, you should first test that torchani is installed, and only then run these scripts. This way such error messages would only mean real errors.
And if torchani isn't available, it should say so and it should say what functionality is disabled because of this reason.

This way it would be less confusing and more informative.

[ghutchis]

avogadro has no way of knowing what packages a script will attempt to load.

I'll see what we can do to tweak the error messages on the script side.

[yurivict]

But you know what is in this script because it is installed by your package.
