In notebook 09b, in the __call__
method of Learner
. If you initialise res
to False
and are always setting it to res and something
, don’t you still get False
, or None
at the end of it?
I test it a little bit here by trying to skip validation and find that I cannot with the current definition.
The version in notebook 05b also appears to be the same. But other versions before that seem ok.
