Update: 2021-12-13 macOS monterey, pytorch0.10.0, torchvision0.11.1
Very slowly
なんでこんなに差がでるんだろ？？
time python main.py --num-processes 2 --epoch 2
（あまりにも遅いのでepoch 2で計測）
| user | system | cpu | total | |

| conda-forge | 53396.66s | 1993.15s | 929% | 1:39:20.09 |
これは使い物にならないレベル。自分でビルドしようぜ！！

Note
ということでIntelと比較。M1速いぜ！
