Cannot Import LearningRateLogger
🐛 Bug
I have been working with the same code in Colab for some time with no issues. Since today, PL could not be imported (#6415). As per linked thread, this is resolved with installing from master, however the following problem still persists:
import pytorch_lightning as pl
from pytorch_lightning.callbacks import LearningRateLogger
ImportError: cannot import name 'LearningRateLogger' from 'pytorch_lightning.callbacks' (/usr/local/lib/python3.7/dist-packages/pytorch_lightning/callbacks/init.py)
