vc384 commented on issue #13928: MXNet 1.5.0 is slower than 1.3.0 when intputs are variant URL: https://github.com/apache/incubator-mxnet/issues/13928#issuecomment-476056800 I met the same problem, I have a project with dilation convolution (resnet backbone). If I use a mxnet1.3.1-cu80 (pip install), the speed is 0.18~0.19s one iter. However, when I switch to mxnet1.4.0-cute80(pip install), the speed drop to 0.19~0.20s one iter. The speed drop slightly, I confused with this problem. OS: Ubuntu 16.04 Driver: 384.130 CUDA: 8.0 cudnn: maybe 7.4.1 or 6.0.21
