Couldn't log learning rate

[amirshamaei]

I addded the following callback config to plot learning rate;however, nothing showed up.
Could you please help me to show learning rate during training?

learning_rate_logger:
  _target_: lightning.pytorch.callbacks.LearningRateLogger
  logging_interval: 'step'

lightning.pytorch.callbacks.LearningRateLogger is renamed to lightning.pytorch.callbacks.LearningRateMonitor according to https://github.com/Lightning-AI/lightning/issues/6418

For the records, here is the snippet, I add it to configs/callbacks/default.yaml

learning_rate_logger:
  _target_: lightning.pytorch.callbacks.LearningRateMonitor
  logging_interval: 'step'
