可能是你的detectron2版本问题。建议按照readme中的指令安装detectron2
pip install -U 'git+https://github.com/CPFLAME/detectron2.git'

I met the same problem. I installed the latest detectron2 (python -m pip install detectron2 -f
https://dl.fbaipublicfiles.com/detectron2/wheels/cu101/torch1.5/index.html).

How can I modify your code to use the official detectron2 instead of your version? Thanks.

感谢作者给出的建议，我重新配置了环境并成功运行了。环境如下：

python 3.7
pytorch 1.5
cuda 10.1
detectron2 用这个来安装pip install -U 'git+https://github.com/CPFLAME/detectron2.git'， 不能按照官方的命令来安装

pip install -U 'git+https://github.com/CPFLAME/detectron2.git'

按照指导安装不成功，请教一下，如何解决？
