ImportError: cannot import name '_is_local_file_protocol' from 'pytorch_lightning.callbacks.model_checkpoint'

When I run
from nemo.collections.tts.models.base import SpectrogramGenerator
I get this error:

I also can't find a function or variable named _is_local_file_protocol in the 'pytorch_lightning.callbacks.model_checkpoint'.

Environment overview

I have used a python virtual environment and installed the requirements with these commands:
apt-get update && apt-get install -y libsndfile1 ffmpeg pip install Cython pip install nemo_toolkit['tts']

Environment details

My pytorch-lightning version is 1.4.0

I had the same issue and updated to pytorch-lightning=2.2.1 and it worked.
Somehow, when I installed everything from scratch, using pip install nemo_toolkit['all'], it did not install the right pytorch-lightning. If you look at the requirements files, it says it requires at least 2.2.1:

cat requirements/requirements_lightning.txt

hydra-core>1.3,<=1.3.2
omegaconf<=2.3
pytorch-lightning>=2.2.1
