Why my GPU Memory Usage increases?

[jeewooyoon-raondata]

I'm currently using the whisper medium model for transcribing 5000 WAV files.

But my GPU Memory Usage is continuously increasing...and it ends up with OOM error..

Can anyone guess what's the problem?

model = whisper.load_model("meidum")

for i in range(5000): 
    # load audio and pad/trim it to fit 30 seconds
    audio = whisper.load_audio(f"audio{i}.mp3") 
    audio = whisper.pad_or_trim(audio)

    # make log-Mel spectrogram and move to the same device as the model
    mel = whisper.log_mel_spectrogram(audio).to(model.device)

    # detect the spoken language
    _, probs = model.detect_language(mel)
    print(f"Detected language: {max(probs, key=probs.get)}")

    # decode the audio
    options = whisper.DecodingOptions()
    result = whisper.decode(model, mel, options)

    # print the recognized text
    print(result.text)
