Return a new executor with the same symbol and shared memory, but different input/output shapes.
Return a new executor with the same symbol and shared memory, but different input/output shapes. For runtime reshaping, variable length sequences, etc. The returned executor shares state with the current one, and cannot be used in parallel with it.
partialShaping
Whether to allow changing the shape of unspecified arguments.
allowUpSizing
Whether to allow allocating new ndarrays that's larger than the original.
kwargs
Map of string to Shape.

returns
executor A new executor that shares memory with this.
