* Renamed `on_sanity_check_start` to `on_train_start` and added `on_train_end` to `ModelHooks`
* changed tests to use `on_train_start` instead of `on_sanity_check_start`
* type: debug
Calculate the adequate number of steps to run during sanity_check.
This fixes the bug when there are two or more validation dataloaders.
- Before: total=self.num_sanity_val_steps
- After: total=self.num_sanity_val_steps*len(self.get_val_dataloaders())
* type: refactor
Put total=... in the next line
* type: refactor
run flake8
* use print for INFO and lower levels summarize()
* use logging.INFO instead of magic number
* bring logging.info back for other cases
* move logging config to __init__.py
* prepend the model summary with a newline
* feat: add reducelronplateau callback
* feat: use reducelronplateau callback in trainer
* feat: only on unsupported lr schedulers
* feat: last but not the least merge of master
* feat: merge master
* feat: support only on scheduler in reduceLrOnPlateauScheduler
* refactor: code style
* Update pt_callbacks.py
* Update trainer.py

* Update train_loop_mixin.py
* Splitted progress bars
* Iterable dataset total batches fix
* Use dynamic ncols and use batch as units
* Count epochs from 1 in progress bar
* Fix for disabled progress bar
* Code simplifications
* Unit tests for num_gpu property as proxy for __parse_gpu_ids.
* Refactoring __parse_gpu_ids
* Moved the function outside the class as it is
an utility function and did not depend on class in any way.
* Added unit tests for it.
* Mocked torch.cuda.device_count function in tests.
This allows the tests to be run on machines that do not have gpus.
* Fixed the parse_gpu_ids function to handle -1 case.
Function now handles -1 the same way as it does for '-1'.
* Unit tests for root_gpu added.
Added backend as a parameter as currently depending on backend set
or not, code fails with exception in certain circumstances, before
giving a wrong answer.
* Moved __set_root_gpu function out of the class.
This function does not depend on the class and can be tested
more easily this way.
Also added unit tests for this function. They simply reuse
data for the root_gpu property.
* determine_root_gpu_device passes unit tests.
* num_gpus passes unit tests.
Also added a None test for this function.
* parse_gpu_ids tests changed to reflect desired state after refactoring.
Planning to refactor parse_gpu_ids to always return list of ints.
This will simplify code that use output of this function.
* * parse_gpu_ids always returns lists
* parse_gpu_ids checks given ids against available ids
* parse_gpu_ids raises exception for non existant ids
* parse_gpu_ids returns None when no gpus are available
* cleaned up determine_root_gpu_device
* cleaned up num_gpus property
* Updated unit tests to reflect changes in the functions
* Flake8 fixes
* Moved fixture code up before where it is used.
* Updated documentation.
* Changed tests to match the API:
* gpus=-1 or gpus='-1' should use all available gpu devices
* gpus=N
* N=0: no gpus should be used.
* N>0: N gpus should be used
* gpus=list of ints or a comma separated string of numbers:
Use the gpus indicated by the list or the string.
* Fixed code to pass all the changed tests for parsing gpus param.
* Refactoring parse_gpu_ids function.
* flake8 fixes.
* Updating documentation.
