yolact++ 训练数据的报错when compiling: ‘TORCH_CHECK_ARG‘ was not declared in this scope 解决办法

用 yolact ++ 训练的时候，对于DCNv2模块，注意： 下来最新的DCNv2版本之后，需要切换到固定的版本，进入 DCNv2 目录下面进行切换 ,不然会报错 pycocotools/_mask.pyx 或者 when compiling: ‘TORCH_CHECK_ARG’ was not declared in this scope error: command ‘g++’ failed with exit status 1
