while i choose O2 to train model, bug: Expected tensor for argument #1 'input' to have the same device as tensor for argument #2 'weight'; but device 1 does not equal 0 (while checking arguments for cudnn_convolution)

Research direction
No file, test, or entry point is identified in the issue. Start by reproducing model training with O2 enabled and the reported CUDA device mismatch, then trace the device placement involved in the cudnn_convolution error. Done means training completes with O2 without input and weight tensors being placed on different devices.
