Method RelaxInput

tensorflow/core/framework/shape_inference.h:278–286

Relax the stored shape of the input in position idx with according to the following rules: - If the ShapeHandles are the same then the stored shape will be returned. - If either of the ShapeHandles are unknown, then a new UnknownShape will be returned. A new shape must be returned because we cannot claim that the resulting shape is necessarily the same as either of the input shapes. - If

  // successful and the new shape differs from the old one, store the new
  // shape and return true. Return false otherwise.
  bool RelaxInput(int idx, ShapeHandle shape) {
    ShapeHandle new_shape;
    Relax(inputs_[idx], shape, &new_shape);
    if (inputs_[idx].SameHandle(new_shape)) {
      return false;
    }
    inputs_[idx] = new_shape;
    return true;
  }
