Trained model does not work during preictions

Hi all,

I trained a 3D Unet for a segmentation task and training works great.
When I now load my model and set the state to model.eval() nothing is working.

The predictions are totally empty.

When I do the same, But with model.train() everything works like a charm.

Has nyone experienced that kind of behaviour?

Thanks in advance,

Cheers,

Michael
