python - 运行时出错 (open-mmlab) C:\mmdetection>python setup.py develop - raise RuntimeError(message)

问题描述

我在来自https://github.com/open-mmlab/mmdetection/blob/master/docs/install.md的 mmdetection 安装的最后阶段收到以下错误

跑步时

raise RuntimeError(message)
RuntimeError: Error compiling objects for extension

我想知道是否有人知道此错误消息的原因可能是什么？

我正在使用 Windows 10

解决方案

使用 cudatoolkit==10.0 而不是 10.2，以便使用 pytorch 1.4 而不是 pytorch 1.5。这解决了这个问题。但是，如果使用 mmdetection v2.0.0 似乎带有 cudatoolkit==10.2 的 pytorch 1.5 可以正常工作。
