Darkflow - 没有名为“darkflow.cython_utils.cy_yolo_findboxes”的模块

我已成功安装 darkflow-1.0.0 (https://github.com/thtrieu/darkflow）在 Windows 10 上使用pip install .命令。

Successfully built darkflow

  Found existing installation: darkflow 1.0.0
    Uninstalling darkflow-1.0.0:
      Successfully uninstalled darkflow-1.0.0
Successfully installed darkflow-1.0.0

之后，我尝试跑步python flow --h，这给了我以下错误：

所以我尝试使用构建 Cython 扩展python setup.py build_ext --inplace命令，这给了我以下错误：

我已经让它在 Linux 上工作了，但我仍然希望它也能在 Windows 上工作。有人可以指出我正确的方向吗？

这是名称冲突：您已通过以下方式成功安装了该软件包pip install .，所以现在darkflow可用于sys.path via site-packages目录。然而，当你跑步时python script.py，当前工作目录被添加到sys.path，所以如果当前目录包含该包darkflow，在安装之前选择site-packages。由于源代码目录不包含共享对象，因此脚本失败。

解决方案是从另一个目录运行脚本，例如

cd %HOMEPATH% & flow -h

或者，如果您需要使用代码，请以可编辑模式重新安装包：

pip uninstall -y darkflow & cd path\to\darkflow-master & pip install -e .

这样，共享对象将被编译并与源代码一起放置，因此您可以运行flow现在从任何地方。
