One consideration is whether to call the base class's impl at the start or end of our impl. If we do it at the start, we are timing these file [operations](https://github.com/NVIDIA/NeMo/pull/10561/files#diff-f55ba91f6545a501940e7d1a054ff848da000f73a361e4ade9fe4fc2e8c4387fR119-R162) as part of the first train time interval. So, I think it makes more sense to do it at the end.

Thanks Maanu! I agree that it makes more sense to add the call at the end.

Upgrade librosa version to fix librosa.display.specshow issue in ASR tutorial notebooks
State: closed | Pull request: yes
Labels: name: cherry-pick


# What does this PR do ?

Matplotlib removed matplotlib.cm.get_cmap 3.9.0 onwards (deprecated since 3.7.0). This causes an error in our ASR tutorials (ASR_for_telephony_speech.ipynb, Speech_Enhancement_with_NeMo.ipynb, Online_Offline_Microphone_VAD_Demo.ipynb) that use librosa.display.specshow, which internally calls matplotlib.cm.get_cmap(name). Librosa fixed it with this PR: [https://github.com/librosa/librosa/pull/1782](https://github.com/librosa/librosa/pull/1782). 
Hence, lower bounding librosa to 0.10.2 in our requirements.txt to account for the above change.

This causes an error in our ASR tutorials (ASR_for_telephony_speech.ipynb, Speech_Enhancement_with_NeMo.ipynb, Online_Offline_Microphone_VAD_Demo.ipynb) that use librosa.display.specshow, which internally calls matplotlib.cm.get_cmap(name). Librosa fixed it with this PR: [https://github.com/librosa/librosa/pull/1782](https://github.com/librosa/librosa/pull/1782). 
Hence, lower bounding librosa to 0.10.2 in our requirements.txt to account for the above change.

fix: cosine annealing linear warmup lr
State: closed | Pull request: yes
Labels: name: core

# What does this PR do ?

`CosineAnnealing` LR with linear warmup and `constant_steps` is `0` on the first step. This causes issues for AdamW optimizer which uses LR for `step_size` in the denominator. This is due to the fact on first step when this method is called `step=0` before the first  optimizer step is complete.

Using the same protection as in:
