Test function
Hello,
My model was worked well on version 0.7.3. Then, I have tried to update the version of pytorch-lightning to 0.8.3.
I have re-trained and tested my model. The training have passed well, but in method test(), I have meet an error:
Traceback (most recent call last):
  File "src/main_cv.py", line 283, in <module>
    main(hyperparams)
  File "src/main_cv.py", line 66, in main
    trainer.test()
  File "/home/vle/miniconda3/lib/python3.7/site-packages/pytorch_lightning/trainer/trainer.py", line 1174, in test
    model = self.get_model().load_from_checkpoint(ckpt_path)
  File "/home/vle/miniconda3/lib/python3.7/site-packages/pytorch_lightning/core/saving.py", line 169, in load_from_checkpoint
    model = cls._load_model_state(checkpoint, *args, **kwargs)
  File "/home/vle/miniconda3/lib/python3.7/site-packages/pytorch_lightning/core/saving.py", line 205, in _load_model_state
    model = cls(*cls_args, **cls_kwargs)
**TypeError: __init__() missing 3 required positional arguments: 'train_loader', 'valid_loader', and 'test_loader'**

Even I have defined test_dataloader function in my model. Could you check if it is a issue of trainer class?
This is my program:
train_loader, valid_loader, test_loader = create_dataloader(...) # I write this function to create the loaders
model = MyModel(hparams, train_loader, valid_loader, test_loader) # define the model and parse data
trainer = pl.Trainer(max_epochs =1 )
trainer.fit(model)
trainer.test()

Many thanks!
