Unknown metric: val_loss

[tobias-tengler]

I followed the tutorial linked on your site, regarding text classification: https://autokeras.com/tutorial/text_classification/
Although I used a different dataset, I get an error that doesn't seem to be related to the dataset.
After the first epoch has been trained and the on_epoch_end callback is executed I get an error: "Unknown metric: val_loss"
Any idea what could be causing this?

The issue was that I was also specifying a non zero-based initial_epoch. Solved.
