theano.tensor.basic.get_vector_length()

This function is a special case of what !ShapeOptimizer does. Make it use !ShapeOptimizer and make sure !ShapeOptimizer handles all the case that this function does.

This will remove duplicate code and allow future optimization when we make `T.shared(const_shape=True)` that allow to take the shape of !SharedVariable and make it constant in the graph.

  • !python
import theano.tensor as tensor
tensor.get_vector_length(tensor.specify_shape(tensor.ivector(), (2,)))


should not raise an error.
