ImportError: No module named 'darkflow.cython_utils'

[k0286]

I installed the repo and build dependences on a clean docker container, according to the instructions in the readme.md.

When I executed the python3 run.py, I got the following error message.

Traceback (most recent call last):
  File "run.py", line 5, in <module>

ImportError: No module named 'darkflow.cython_utils'

I also tried to install darkflow form thtrieu directly and got the same error.

I've searched similar issues both on Google and Stack overflow, but I don't find a feasible solution.

I am getting the same error. Did you figure out ?

@k0286 @sukhad-app seems like a bug. I've installed darkflow globally. This helped me avoid "init darkflow.cython_utils.cy_yolo_findboxes" problem

Same error here

I had the same error: I found the darkflow.cython_utils where here: ./Tracking-with-darkflow/darkflow/darkflow/cython_utils ..instead of here ./Tracking-with-darkflow/darkflow/

So I copied the folder cython_utils into ./Tracking-with-darkflow/darkflow/, and that solved for me.

Instead of building darkflow inside the tracking with darkflow directly. Install darkflow globally. It would work.

Copying the cython_utils folder did not work for me. And how do I install darkflow globally? Thanks

[nathangq]

it seems a problem about path, there is a way around with some modification :

1. delete Tracking-with-darkflow/darkflow/init.py
2. pip uninstall darkflow
3. cd into Tracking-with-darkflow/darkflow, run command "python3 setup.py build_ext --inplace", if succeed, you will find .so files in darkflow/darkflow/cython_utils/
4. mv Tracking-with-darkflow/run.py to Tracking-with-darkflow/darkflow/run.py, and modify import of run.py such that from darkflow.defaults import argHandler #Import the default arguments from darkflow.net.build import TFNet
5. config yolo cfg, weight, disable tracker
6. run run.py, till now the detection should work

7. activate tracking, and set tracker to deep_sort, run and you will see some path errors, fix one by one, for example in darkflow/darkflow/net/helper.py

   if self.FLAGS.tracker == "deep_sort":
       import sys
       sys.path.insert(0,"/home/Tracking-with-darkflow")
       from deep_sort import generate_detections

in darkflow/darkflow/net/yolov2/predict.py

    try :
            import sys
            sys.path.insert(0,"/home/Tracking-with-darkflow")
            from deep_sort.application_util import preprocessing as prep

to make python know the path

after this detection with deep_sort tracker could work

A simple, quick, and safe workaround is to copy darkflow/darkflow/cython_utils and darkflow/darkflow/utils to darkflow/cython_utils and darkflow/utils respectively.

Thanks

instead of use python3 setup.py build_ext --inplace you should use pip install .

[KaranFriends]

simply build the module globally, it will work.

[italojs]

install in dev mode pip install -e .

[mujeebishaque]

Lookup the annotation files in your directory. See if it contains anything else except .xml files. If yes, remove it and re-run. It will work.

I had the same problem, I was trying to import it from the Anaconda env. But then I noticed that my win10 python version and the anaconda env's was different. Just created a new env with the same python version (3.6.8) as my win10 and had a clean install of darkflow again(using 'python3 setup.py build_ext --inplace' first tried other two options but they did no good), that fixed the problem. I switched to a new env because I had nothing important in the present one and also didnt want to risk it. Maybe it will also work without installing stuff from scratch. Now I cant import it to PyCharm even though I added the darkflow dir to pycharm path, would be awesome if someone can help. Good luck.
