Inconsistent inference accuracy of pytorch model caused by cuda version #283

When I use the gpu version of pytorch for model inference, I found that the output tensor accuracy is inconsistent, as follows: Screenshot from 2024-07-16 12-22-10

When I switch to cpu, this problem does not occur. Furthermore, I can also get consistent results when using lower cuda versions (11.6->11.3). Screenshot from 2024-07-16 12-25-53
