Device-aware Tensor hash

Is there a GPU equivalent hash implementation for the Tensor wrapper bellow? I want sto store unique multi-dimensional tensors in a set.

"""Wrapper to store tensors in a set."""

import torch

class HashTensor:
    def __init__(self, obj):
        self.obj = obj

    def __hash__(self):
        return hash(self.obj.cpu().numpy().tobytes())

    def __eq__(self, other):
        if isinstance(other, HashTensor):
            return torch.equal(self.obj, other.obj)
        elif isinstance(other, torch.Tensor):
            return torch.equal(self.obj, other)
        return False

    def __repr__(self):
        return repr(self.obj)
