Non-streaming transcription throws exception: 'Queue' object has no attribute 'round_robin' #8

Closed xtsoukala closed 2 years ago

Running kaldigrpc-transcribe without the --streaming flag throws the following exception:

  File "/home/ctsoukala/.local/lib/python3.8/site-packages/kaldigrpc_client/client.py", line 102, in recognize_wav
    res = self.recognize(AudioSegment.from_file(wav_file).raw_data)
  File "/home/ctsoukala/.local/lib/python3.8/site-packages/kaldigrpc_client/client.py", line 74, in recognize
    return self.connection.Recognize(req)

The server didn't output a relevant error, it only showed:
