Meet some distributed training problems while adding some conv layers #50

Hello, thank you for such a wonderful job!I have a question that I hope you can answer. image I added some convolution layers before segnet's self.bev_compressor. Why did my modification result in 100% utilization on GPU0, and 0% utilization on GPU1.2.3 even though there is the same memory footprint as GPU0? And the program neither reports errors nor continues running,it just stuck there.
