从子目录

Question

我正在进行一些对象检测，我正在尝试使用yolo对象检测的darkflow代码，该代码可以自述，如自述文件中所述。但是，为了使程序文件夹更清洁，我试图将darkflow程序的所有文件和文件夹分组到一个父文件夹中。 当我这样做时，我将所有导入功能更新为darkflow.<sub folder>，但是当我使用cyton文件运行程序时出现错误。 cython_utils文件夹中的每个文件都已更新，以容纳额外的父目录，并在更新后重新编译，如自述文件中所述。错误是

File "/media/GIT/objdetect/darkflow/net/yolo/test.py", line 7, in <module>        
from darkflow.cython_utils.cy_yolo_findboxes import yolo_box_constructor 
File "cython_utils/cy_yolo_findboxes.pyx", line 1, in init cython_utils.cy_yolo_findboxes (cy_yolo_findboxes.c:18758)
ImportError: No module named 'cython_utils'

我尝试使用可靠路径来查找文件，以及finding the parent directory automatically但都没有用。

当我编译cython_utils文件夹时，我会收到一些警告，（完整输出在下面进一步发布）

Warning: Extension name 'nms' does not match fully qualified name 'cython_utils.nms' of 'nms.pyx'
Compiling nms.pyx because it changed.

如何使用cython编译的文件夹添加父文件夹？

这是我第一次处理cython模块，我认为只需更改每个模块的路径位置然后重新编译。

注意：如果我注释掉导入行以及使用代码的位置，则程序完成且没有错误。

例如我想要的。

project/
   -> darkflow/
         -> cfg/
             -> other subfiles
         -> cython_utils/
             -> build/
                 -> temp.linux-x86_64-3.5/
                     -> cy_yolo2_findboxes.o
                     -> cy_yolo_findboxes.o
                     -> nms.o
             -> cy_yolo_findboxes.c
             -> cy_yolo_findboxes.pyx
             -> other files
         -> dark/
             -> other subfiles
             .
             .
             .
   -> main.py

什么有效。

project/
     -> cfg/
         -> other subfiles
     -> cython_utils/
         -> build/
             -> temp.linux-x86_64-3.5/
                 -> cy_yolo2_findboxes.o
                 -> cy_yolo_findboxes.o
                 -> nms.o
             -> cy_yolo_findboxes.c
             -> other files
         -> dark/
             .
             .
             .
     -> main.py

编译cython
