Will this properly separate out the messages? We might want to add a line break in between the w.message elements
There was a problem hiding this comment.
Yes, it prints a list of str, so it is easy to separate the messages :)
a = ["foo", "bar", "baz"]
raise ValueError(str([msg for msg in a]))
# ValueError: ['foo', 'bar', 'baz']

What does this PR do?
Fixes #29665
We don't allow saving bad generation config files (i.e. ones whose validation has warnings or exceptions). This check was only done at save time, which happens AFTER training. This PR introduces the same check in the trainer's
__init__, to fail early (and before spending time/$)
