Error when having multiple candidates for dependencies.

[anntzer]

Sounds reasonable to add a -d/--depends python-pytorch or similar flag to allow the end user to 1) manually specify additional depends and 2) resolve such ambiguities. A patch would be welcome.

[fengwang]

@anntzer Maybe you we can skip all the candidates from here without breaking the pipeline, and remind the user to install it afterwards?

[anntzer]

Sure, that seems fine too, but I would prefer protecting that under a --skip-ambiguous-deps option.
