BUG1：RuntimeError: cuda runtime error (59) 

错误信息如下所示：

THCudaCheck FAIL file=/opt/conda/conda-bld/pytorch_1549628766161/work/aten/src/THC/generic/THCTensorMath.cu line=24 error=59 : device-side assert triggered
Traceback (most recent call last):

发现在计算loss的时候报错了，于是查看数据集和网络结构，发现最后一层的fc的输出类别小于数据集中的类别，将二者统一后错误消除
