> I'm not sure. Can you explain why "comparison among rank-0 tensor is ambiguous"? I guess [here](https://github.com/apache/tvm/blob/main/python/tvm/te/tensor.py#L89-L95), the `tensor.equal(other)` and `tensor.same_as(other)` is not suitable for non rank-0 tensors, so it adds the check. 1. Reference check makes no sense because the address of the tensor is changed every time when invoking `op.output(id)`. 2. Content checks have some constraints, such as **Tensor dimension** needs to be matched. All these two ways cannot be put into the `__eq__` method. But they may make sense for rank-0 tensors. A possible fix for this would be simply to delete [it](https://github.com/apache/tvm/blob/main/python/tvm/te/tensor.py#L89-L95). ```python def __eq__(self, other): if not isinstance(other, Tensor): if isinstance(other, _expr.ExprOp): return _expr.EqualOp(self, other) return False return _ffi_api.TensorEqual(self, other) ``` -- This is an automated message from the Apache Git Service.
