Log both loss and metrics on both train and eval dataset into a csv file

[anais2390]

Hello,
I am using monai librairy for segmentation and I've been looking for the cleanest way to log at each epoch:

• mean loss computation on train dataset
• mean metrics computations on train dataset
• mean loss computation on eval dataset
• mean metrics computations on eval dataset
• learning rate

I am using engine SupervisedTrainer and SupervisedEvaluator and the trickest part is that the output_transforms are different for loss computation (no postprocessing) and metrics computation (activation + asdiscrete).
Also I coudn't manage to get the loss values into the csv.

A typical csv file sould contain the following columns (if we use the MeanDice metric for exemple)

Epoch | MeanDice_train | MeanDice_eval | Loss_train | Loss_eval |

Thank you so much for your help.
