train error

[Zoinye]

hey! I have tow problems and My torch version is 1.12! Seemly error is due to fps_pred, y_pred = model(x) .

1. The first one is division by zero .I try to use loss.item() to replace `loss.data[0],but it not work! The whole error is

Traceback (most recent call last): File "D:\project\python2\CCPD-master\rpnet\rpnet.py", line 422, in model_conv = train_model(model_conv, criterion, optimizer_conv, num_epochs=epochs) File "D:\project\python2\CCPD-master\rpnet\rpnet.py", line 412, in train_model print('%s %s %s\n' % (epoch, sum(lossAver) / (len(lossAver)), time() - start)) ZeroDivisionError: division by zero`.

2. The other is RuntimeError: adaptive_max_pool2d(): Expected input to have non-zero size for non-batch dimensions, but input has sizes [1, 64, 0, 0] with dimension 2 being empty.The two dimensions are zero and I don't know how to solve it!

The whole error is
