chinakook opened a new issue #7596: "is_1x1_" in convolution operator is not really used
URL: https://github.com/apache/incubator-mxnet/issues/7596
 
 
   I found that "is_1x1_" in convolution-inl.h is not really used.  MXNet just create the "is_1x1_" but not use it to skip the im2col function call. In contrast, the "is_1x1_" in Caffe is really used to skip im2col function call to accelerate the 1x1 convolution. It is very important in some cases such as the Google's Mobilenet.
