Hi there, I’m new to mxnet and wondering how to multiply a shape=[22,11] tensor A and another tensor with shape=[22,11,100]. The third axe 100 is batch size, I’d like to elementwise multiply these [22,11] tensors, and broadcast the multiplication to batch dimension.

A * B gives error:

elemwise_binary_broadcast_op.h:68: Check failed: l == 1 || r == 1 operands could not be broadcast together with shapes [22,11] [22,11,100]

Any hints? Thank you.
