NO LOGITS RETURNS AFTER GENERATE

[LAnCeBabY]

after ctranslate2.models.Whisper.generate, result does not include "logits"
version == 4.4.0

Do you set the return_logits_vocab=True?

Do you set the return_logits_vocab=True?

Yes. But I didn't find logits in WhisperGenerationResults

Can you send me the code? I will test it.

Can you send me the code? I will test it.

The code is modified from faster-whisper
result = self.model.generate( encoder_output, [prompt], length_penalty=options.length_penalty, repetition_penalty=options.repetition_penalty, no_repeat_ngram_size=options.no_repeat_ngram_size, max_length=max_length, return_logits_vocab=True, return_scores=True, return_no_speech_prob=True, suppress_blank=options.suppress_blank, suppress_tokens=options.suppress_tokens, max_initial_timestamp_index=max_initial_timestamp_index, **kwargs, )

And I have printed the WhisperGenerationResult class. Seems no ‘logits’ in this class.

Seems to be missing from the Python wrapper

In version v4.5.0, logits is present in WhisperGenerationResult, but it contains an empty value:
result.logits -> [[ [cpu:0 float32 storage viewed as ]]]

I'm wondering if this is expected or if it's possible to retrieve meaningful values for logits. Other transcription-related aspects are working fine.

thank you.
