The current use of
decoder_moduleassumes thatencoder_hidden_statesis the fourth positional argument of the decoder's call method. We see that this is indeed true of the two current Flax decoder models:FlaxGPT2LMHeadModelandFlaxBartForCausalLM. However, for other possible decoder models, such as the work-in-progressFlaxBertForCausalLM, there may be additional positional arguments (such astoken_type_idsorhead_mask) prior toencoder_hidden_states. To handle this more general case, we should not assumeencoder_hidden_statesis necessarily the fourth positional argument, and should instead pass it as a key-word argument.
