The Python API currently displays metrics in the following format during training:
[0] validation_0-mlogloss:6.93514 validation_1-mlogloss:6.98867
[1] validation_0-mlogloss:6.46165 validation_1-mlogloss:6.53638
[2] validation_0-mlogloss:6.12659 validation_1-mlogloss:6.22222
...
Is it possible to use a callback for custom formatting and have the output look more like:
6.93514,6.98867
6.46165,6.53638
6.12659,6.22222
