Correct and it is so in both cases only assuming there are no other vars that refer to learn.
learn.destroy is almost ready, you can try:
def destroy(self):
"Free the Learner internals, leaving just an empty shell that consumes no memory"
attrs = [k for k in self.__dict__.keys() if not k.startswith("__")]
for a in attrs: delattr(self, a)
gc.collect()
but it’s not @sgugger approved yet.
You just call:
learn.destroy()
no need for del, None, gc.collect()
