i downloaded model from facebook / blenderbot_small-90M , and loaded it with
BlenderbotSmallForConditionalGeneration.from_pretrained() respectively. When i looked into trainable_variables using:
for v in model.trainable_variables(): print(v)
i found they were equal, but doc says there is a a language modeling head in
TFBlenderbotSmallForConditionalGeneration, how can i get the weights of the head?
