Mac上复现时报错。

[Jss Shepherd]

mac在conda环境中复现fastreid：
安装依赖包时，faiss-gpu无法安装报错，但faiss-cpu可以安装
之后运行train_net.py时报错
运行命令：
python3 tools/train_net.py --config-file ./configs/Market1501/bagtricks_R50.yml MODEL.DEVICE "cuda:0"
报错：
Traceback (most recent call last):

之后又搜到了cpu训练命令，还是报错
运行命令：
python3 tools/train_net.py --config-file ./configs/Market1501/bagtricks_R50.yml MODEL.DEVICE "cpu"
报错：

Mac是集成显卡的版本，可以解决此问题吗？谢谢🙏！
