  --- BEGIN ISSUE ---
  Comet PAPI Depreciated
  Use of the Comet API logger reports an unecessary depreciation warning relating to the use of comet_ml.papi, rather than the newer comet_ml.api.
  
  Example:
  `COMET WARNING: You have imported comet_ml.papi; this interface is deprecated. Please use comet_ml.api instead. For more information, see: https://www.comet.ml/docs/python-sdk/releases/#release-300`

  2 Log using `comet <https://www.comet.ml>`_
  3 
  4 Comet logger can be used in either online or offline mode.
  5 To log in online mode, CometLogger requries an API key:
  6 
  7 .. code-block:: python
  8 
  9     from pytorch_lightning.logging import CometLogger
  10     # arguments made to CometLogger are passed on to the comet_ml.Experiment class
  11     comet_logger = CometLogger(
  12         api_key=os.environ["COMET_KEY"],
  13         workspace=os.environ["COMET_WORKSPACE"], # Optional
  14         project_name="default_project", # Optional
  15         rest_api_key=os.environ["COMET_REST_KEY"], # Optional
  16         experiment_name="default" # Optional
  17     )
  18     trainer = Trainer(logger=comet_logger)
  19 
  20 To log in offline mode, CometLogger requires a path to a local directory:
  21 
  22 .. code-block:: python
  23 
  24     from pytorch_lightning.logging import CometLogger
  25     # arguments made to CometLogger are passed on to the comet_ml.Experiment class
  26     comet_logger = CometLogger(
  27         save_dir=".",
  28         workspace=os.environ["COMET_WORKSPACE"], # Optional
  29         project_name="default_project", # Optional
  30         rest_api_key=os.environ["COMET_REST_KEY"], # Optional
  31         experiment_name="default" # Optional
  32     )
  33     trainer = Trainer(logger=comet_logger)
  34 
  35 
  36 Use the logger anywhere in you LightningModule as follows:
  37 
  38 .. code-block:: python
  39 
  40     def train_step(...):
  41         # example
