Cannot run ASR_with_NeMo.ipynb example
I cannot run the example through CoLab, it stucks in loading in pre-trained model.


# This line will download pre-trained QuartzNet15x5 model from NVIDIA's NGC cloud and instantiate it for you
quartznet = nemo_asr.models.EncDecCTCModel.from_pretrained(model_name="QuartzNet15x5Base-En")


AttributeError: module 'math' has no attribute 'prod'

If I use v1.12.0 instead main branch, there will be no problem.
