Method _check_for_tensor_struct_info

python/tvm/relax/expr.py:249–264

Raise an error if this is something other than a Tensor Used for early checks in `expr.dtype` and `expr.shape` accessors. While invalid usage would cause errors to be raised during shape inference, an earlier check makes it easier to find the invalid usage.
