python - Darkflow——没有名为 'darkflow.cython_utils.cy_yolo_findboxes' 的模块

Question

我已使用 pip install . 命令在 Windows 10 上成功安装 darkflow-1.0.0 ( https://github.com/thtrieu/darkflow )。

Successfully built darkflow
Installing collected packages: 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

此后，我尝试运行python flow --h，这给了我以下错误:

Traceback (most recent call last):
  File "flow", line 4, in <module>
    from darkflow.cli import cliHandler
  File "C:\Users\filda\Desktop\FIT_VUT\BP\YOLO\YOLO_keras\darkflow\darkflow\cli.py", line 3, in <module>

    from ...cython_utils.cy_yolo_findboxes import yolo_box_constructor
ModuleNotFoundError: No module named 'darkflow.cython_utils.cy_yolo_findboxes'

因此，我尝试使用 python setup.py build_ext --inplace 命令构建 Cython 扩展，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？

Answer 1

这是一个名称冲突:您已通过 pip install 成功安装了该软件包。，因此现在 darkflow 在 sys.path 中可用通过 site-packages 目录。但是，当您运行 python script.py 时，当前工作目录会添加到 sys.path 之前，因此如果当前目录包含包 darkflow >，它是在 site-packages 中安装的之前选择的。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，因此您现在可以从任何地方运行 flow。
