torch.Tensor.to(<int num>) failed on npu

🐛 Bug Report

As per title. When I execute torch.ones(2).to(0), the following error occurs:

(inference) [root@node-35 inference]# python

Versions

# pip list | grep torch
torch              2.1.0
torch-npu          2.1.0.post20231207

Expected behavior

torch_npu supports torch.Tensor.to(<int num>
