Problem installing NeMo from pip
which pip version do you have? Could be a problem with your environment. Are you able to pip install other packages? Like this: ```pip install pytorch-lightning==1.1.4``` ? I literally copy-pasted this: ```pip install nemo_toolkit[all]==1.0.0rc1``` and it worked.
Hi,

I have a problem installing NeMo from pip. I'm using the instructions [here](https://docs.nvidia.com/deeplearning/nemo/user-guide/docs/en/stable/starthere/intro.html#pip)

Following them, I'm getting:
```

zsh: no matches found: nemo_toolkit[all]==1.0.0rc1
```

What should I do to install NeMo?

My environment:
