ValueError: NeMo ASR collection is not installed. when run ./normalize_with_audio.py
When I run the following command

python ./normalize_with_audio.py  --text=" Hold on one second. 429-020"  --language=en --n_tagged=10 --cache_dir="cache_dir" --audio_data="./0001_00002.wav" --model="QuartzNet15x5Base-En" --verbose

I always get the error:
Traceback (most recent call last):
  File "./normalize_with_audio.py",  in <module>
    raise ValueError("NeMo ASR collection is not installed.")
ValueError: NeMo ASR collection is not installed.


I have install  nemo all
