When does this happen?

IF After saving and reloading a WhisperForConditionalGeneration model with transformers >=4.50.0, calling generate() raises ValueError about forced_decoder_ids being explicitly specified.

How others solved it

THEN Reset generation_config.forced_decoder_ids to None before generation, or manually convert forced_decoder_ids to input_ids/decoder_input_ids. The recommended fix is to set model.generation_config.forced_decoder_ids = None after loading, or ensure the saved config does not contain forced_decoder_ids.

# After loading a saved Whisper model:
model = WhisperForConditionalGeneration.from_pretrained('saved_tiny')
model.generation_config.forced_decoder_ids = None
# Then generate normally
