Hard error using dice loss

General Usage

Cheers,

Regardless of the model, data, or any other condition, I’ve never been able of using the built-in Flux.dice_coeff_loss() function. A very long error dump shows up, apparently tied to CUDA and memory usage

For the error dump from below, which is limited to 1/10 of it, my model is a simple CNN, labels are binaries, and predictions are limited by sigmoid.

Any advice is greatly appreciated. Thanks.
