When I try to calcuate the loss value of the expected value and the label value,I got the exception, even though there are some simliar topic, but I still cannot found the solution.
Can you help me?

RuntimeError: cuda runtime error (59) : device-side assert triggered at /pytorch/aten/src/THC/THCReduceAll.cuh:327
My code is
for step,(x,y1) in enumerate(train_loader):
x_data, y_model = x.to(device), y1.to(device)
optimizer.zero_grad()
output_model = model(x_data, h0)
print("output_model.shape:", output_model.size())
print("y_model.shape:", y_model.size())
print("output_model:", output_model)
print("y_model:", y_model)
loss_model = loss_func(output_model, y_model)
print("loss_model:", loss_model) # the error occured in this line.
the printed result is:
output_model.shape: torch.Size([64, 2])
y_model.shape: torch.Size([64])
