完整报错如下：

RuntimeError: CUDA error: device-side assert triggered
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

有很多愿意会导致这个CUDA triggered的Error，我的问题是在于网络前半部分都是卷积层，在最后一层使用了全连接层，而在最后一层我的输出并没有和类别相匹配。例如，原先多分类我用的是十个类别，更改成二十二种类别后忘记改输出的类别了，将类别和输出channel相匹配便解决了。
