在python numpy中使用一个张量产品，而不执行一个和。

I have two tensors, each 2D, with a common long axis (eg 20.000) and diffenrent short axes eg one 9 the other 10). I want to end up with a 9X10X20000 tensor, such that for each location on the long axis, the other two axes are the tensor product. Explicitly, with the "long" axis here 4, I want to do:I have two tensors, each 2D, with a common long
