re-compilation error

[jjh6297]

hi, I'm trying to modify dropout rate per each task recently.

For that, I should change dropout rates of the layer, and re-compile.

However, it makes error of

'You must feed a value for placeholder tensor 'dense_1_target' with dtype float and shape [?,?]'

Additionally, when I re-compile the model without any change, it also makes same error at model.fit.

Is there a way to re-compile?

I also attach the full error at the end.

Thanks
