Running on T4

I am trying to get a minimalistic replication of the streaming behavior. I eventually arrived at this code:

import time
import soundfile as sf
from src.simuleval_transcoder import SimulevalTranscoder
from src.simuleval_agent_directory import SimulevalAgentDirectory, AgentWithInfo
from src.transcoder_helpers import get_transcoder_output_events


agent_directory = SimulevalAgentDirectory()
pre_agent = agent_directory.build_agent_if_available("SeamlessStreaming", "vad_s2st_sc_main.yaml" )
agent = AgentWithInfo(pre_agent, 'SeamlessStream', 's2t', 'en')
transcoder = SimulevalTranscoder(
    agent,
    sample_rate=16000,
    debug=True,
    buffer_limit=5
)
transcoder.start()
# Function to simulate streaming audio
def stream_audio(file_path, chunk_size=320):
    with sf.SoundFile(audio_file_path, 'r') as f:
        while True:
            data = f.read(chunk_size)
            if len(data) == 0:
                break
            yield data

# Stream the audio and transcribe
audio_file_path = "converted_file.wav"
for chunk in stream_audio(audio_file_path):
    # Process incoming bytes
    transcoder.process_incoming_bytes(chunk, dynamic_config={"targetLanguage": "en"})

    # Check for transcription output
    events = get_transcoder_output_events(transcoder)
    for event in events:
      print(event)
      if event['event'] == 'translation_text':
          print(event['payload'])  # Print the transcribed text
    time.sleep(0.02)

# Finalize
transcoder.close = True

But something appears to be wrong, because although I can see the GPU is being utilized,

get_transcoder_output_events(transcoder)

never returns any event. Am I doing something wrong?
