[Error] On running this tutorial notebook on Colab
## ASR Tutorial - Online_Offline_Speech_Commands_Demo.ipynb


I tried to execute the notebook in google colab (`https://github.com/NVIDIA/NeMo/blob/stable/tutorials/asr/Online_Offline_Speech_Commands_Demo.ipynb`) 

While running the code block:


```python
wave_file = demo_wave

CHANNELS = 1
audio, sample_rate = librosa.load(wave_file, sr=SAMPLE_RATE)
dur = librosa.get_duration(audio)
print(dur)
``` 

The below error is produced:
```bash
