Cannot install

[ju-sh]

Describe the bug
Looks like the package versions in requirements.txt files are too
loose.

First, got error about NeptuneLogger not being found. And further
errors even if that is ignored.

Steps/Code to reproduce bug

pip install torch torchvision torchaudio
pip install packaging
pip install huggingface_hub==0.23.2

git clone https://github.com/AI4Bharat/NeMo.git
cd NeMo/
bash reinstall.sh
python3 hello.py

where hello.py is like:

import nemo.collections.asr as nemo_asr
import torch

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

model_path = "/home/username/indicconformer_stt_ml_hybrid_rnnt_large.nemo"
model = nemo_asr.models.EncDecCTCModelBPE.restore_from(restore_path=model_path)

model.freeze()
model = model.to(device)

Error:

$ python3 hello.py
