[dynamo][numpy] Add NumpyTensorVariable to translate ndarray attribute calls to tensor attributes (#95849) Issue: #93684 # Problem Reduce graph breaks when dynamo compiles python functions containing numpy functions and ndarray operations. # Design (as I know it) * Use torch_np.ndarray(a wrapper of tensor) to back a `VariableTracker`: `NumpyTensorVariable`. * Translate all attributes and methods calls, on ndarray, to torch_np.ndarray equivalent. This PR adds `NumpyTensorVariable` and supports: 1. tensor to ndarray, ndarray to tensor 2. numpy functions such as numpy.meshgrid() 3. ndarray attributes such as `itemsize`, `stride` Next PR will handle returning `np.ndarray` and add support for ndarray methods Pull Request resolved: https://github.com/pytorch/pytorch/pull/95849 Approved by: https://github.com/ezyang
