Hi,

I try to run your code in multi gpu and got below error: [02:05:22] /home/ec2-user/mxnet/dmlc-core/include/dmlc/./logging.h:300: [02:05:22] src/operator/tensor/./matrix_op-inl.h:151: Check failed: oshape.Size() == dshape.Size() (7680 vs. 3840) Target shape size is different to source. Target: (128,60,1) Source: (64,60)

Could you please share your idea about it. Thanks

mxnet slices the batch to do a data parallelization which causes this error.
