Custom Text Logger example
I am using Neptune.ML for logging, but I would like to keep the data for analysis locally.
Trying to write a simple logger that dumps info to the CSV files.
train.csv like:
step, loss1, loss2
1, 0.5, 0.4
2, 0.4, 0.12
....

val.csv should look like:
epoch, loss1, loss2
1, 0.6, 0.23
2, 0.13245, 0.2134
....

I am looking at the docs at https://pytorch-lightning.readthedocs.io/en/latest/loggers.html
and at the examples in https://github.com/PyTorchLightning/pytorch-lightning/tree/master/pytorch_lightning/loggers
and cannot figure out how to do this.
It would be nice if you extend the documentation with a more detailed example.
