I'm trying to get the loss from a test image in Faster R-CNN.

If I run copy.copy(trainer.previous_minibatch_loss_average) right after trainer.train_minibatch(data) then I can get the loss out for the trained image(mb=1). When I try to do the exact same after trainer.test_minibatch(data) I get: This Value object is invalid and can no longer be accessed.

I've been looking around and it seems that other may have accomplish with something similar. Here.

Anyone know what to do to get the loss of a test image?

results = []
results.append(trainer.previous_minibatch_loss_average)

The above should work.
