Transcription error related to BatchedInferencePipeline and numpy

[shkstar]

I am using BatchedInferencePipeline of faster whisper in Google Colab by

! pip install --force-reinstall "faster-whisper @ https://github.com/SYSTRAN/faster-whisper/archive/refs/heads/master.tar.gz"
! pip install ctranslate2==4.4.0

Today when I execute the transcription it showed below error msg:

TypeError: expected np.ndarray (got numpy.ndarray)

May I ask what is the problem and how to solve? It is weird that it used to work without problems.

please use a debugger and check the value of audio or upload the audio file here

I turn youtube video to wav using ! pip install yt-

Type of video_path_local: <class 'str'>
File exists: True

Should be solved after #1106
