ModuleNotFoundError: No module named 'nms'

after building darkflow, i ran command python flow --h and it gave following error.

Traceback (most recent call last):

pip install nms

If use pip install nms will face this...

    from cython_utils.cy_yolo_findboxes import yolo_box_constructor
  File "cy_yolo_findboxes.pyx", line 1, in init cy_yolo_findboxes
AttributeError: module 'nms' has no attribute '__pyx_capi__'

It should be used nms from cython_utils not from pip.

can you specify how to install it from cython_utils thanks

Spent ~5 hours on this. For Windows with new virtual environment I had 'no module named nms' error. Solved in two steps:

1. In file setup.py cut name of each Extension to the short one: "darkflow.cython_utils.nms" -> "nms".
2. Step 1 went me to the next error with relative path import error in nms.pyx. Solution I found is to use absolute module path in nms.py line 5: 'darkflow.utils.box' instead of '..utils.box'.

I hope it will help to you too.

1. download the https://github.com/thtrieu/darkflow
2. run command ： pip install -e . in the project “darkflow”
3. copy the two folder “darkflow” and “darkflow.egg-info” into our yolo_object_detection project. (replace the original folder "darkflow")
4. run command : flow --mode cfg/yolo.cfg to test if everything works fine
