How can I get symbol shape of a layer as input of another layer in run time? Not with ”infer_shape“

[summerlvsong]

Description

When I try to use "mx.symbol.Deconvolution", I find it hard to set the the parameter "target_shape". I want it to deconvolute the input to a specific shape of a former layer, So I think I have to set "target_shape" to the shape of the former layer, It is right?
However, I cannot find a way to acquire the output shape of the former layer in run time.
