退出时资源未释放

[hipudding]

复现方法：

import torch
import torch_npu

s = torch.npu.Stream()
print(s)
x = torch.randn(2, 2).npu()
y = torch.randn(2, 2).npu()

with torch.npu.stream(s):   
    z = x.mm(y)

print(z)

ctrl+C后，报错如下：

/home/hua/miniconda3/envs/pt/lib/python3.10/multiprocessing/resource_tracker.py:224: UserWarning: resource_tracker: There appear to be 41 leaked semaphore objects to clean up at shutdown
warnings.warn('resource_tracker: There appear to be %d '

直接python直接文件不会报错
