hi all , I have a problem, I use tvm to speed up resnet101(mxnet) on 1080ti, I try to use group conv, but after I set group =2, the speed became slower too much. Then I try to speed up resnext101(mxnet). ResNext also became more slower . So , do tvm not support group conv (mxnet ) ?
To get more information , I try to set group = 32, after tvm speed up , it is more faster then group = 2.
if group = 1 , after tvm , process one image cost 6ms, if group = 2 , cost about 200ms, group = 3 cost 17ms. When group =2 , the speed is the slowest.
Can anyone solve the problem?
