<!-- ### Common bugs: 1. Tensorboard not showing in Jupyter-notebook see [issue 79](https://github.com/PyTorchLightning/pytorch-lightning/issues/79). 2. PyTorch 1.1.0 vs 1.2.0 support [see FAQ](https://github.com/PyTorchLightning/pytorch-lightning#faq) --> ## 🐛 Bug <!-- A clear and concise description of what the bug is. --> Progress bar epoch starts at 1, but in ModelCheckpoint it starts at 0. ### To Reproduce Steps to reproduce the behavior: https://github.com/PyTorchLightning/pytorch-lightning/blob/8ca8336ce52ee7379f4d399520636143eb31018b/pytorch_lightning/callbacks/progress.py#L320 https://github.com/PyTorchLightning/pytorch-lightning/blob/8ca8336ce52ee7379f4d399520636143eb31018b/pytorch_lightning/callbacks/model_checkpoint.py#L212 <!-- If you have a code sample, error messages, stack traces, please provide it here as well --> ### Expected behavior Shouldn't they be consistent?
