NotImplementedError: The following operators are not implemented: ['aten::grid_sampler']

I met this error when trying to convert scripted_model to relay.

mod, params = relay.frontend.from_pytorch(scripted_model, shape_list)

Is it because relay don’t support grid_sampler? Should I add a new op in relay following this link(Adding an Operator to Relay — tvm 0.9.dev0 documentation) or is there any other solution? Pls help me solve this problem.
