Building module darkflow.darkflow.cython_utils.cy_yolo_findboxes failed

[tonmoyborah]

I have installed cython using pip and still have this error when I run run.py.
I think I have all the dependencies in place and have step by step instructions you provided. Any idea why this error pops?
I am using python2.7, tf 1.2, cython 0.28

[tonmoyborah]

Is it necessary to use python3 for this. Is there any way to use python2.7? The full error stack is -

python run.py

Dear @tonmoyborah,
I have also faced your problem. I have used TensorFlow 1.7 (GPU Based), Python 3.5, (CUDA 9.0 & cuDNN 7) and all packages installed via pip3 install.

[tonmoyborah]

@ahkarami your problem would be mainly because of your Cython imo. Cython has this issue of having different versions for different versions of python. So I think you should verify your cython. First step would be to try to import cython in a python 3.5 env.

[ahkarami]

I can use & import cython in python3. however the above-mentioned problem is remained.

I have also faced your problem.
C:\Users\Admin.pyxbld\temp.win-amd64-3.5\Release\pyrex\darkflow\darkflow\cython_utils\cy_yolo_findboxes.c(435): fatal error C1083: Cannot open include file: 'numpy/arrayobject.h': No such file or directory
I don't know how to solve.

[tonmoyborah]

@AlexMistletoe your issue might be a little different. Try copying cython_utils folder from inside darkflow directory i.e. /Tracking-with-darkflow/darkflow/cython_utils to /Tracking-with-darkflow/cython_utils

[Yolymaker]

@tonmoyborah Thanks,but the problem now is:ImportError: No module named 'darkflow.darkflow.cython_utils.cy_yolo_findboxes' when I run the run.py

[me6ran]

I got the same error as below, when I run ./flow --h

ImportError: No module named cy_yolo_findboxes
I can import cython without any problem in my python code:

import cython
cython.version

any idea?

Exactly my same error. I tried to follow @tonmoyborah 's suggestion but the problem persist. I was hoping to move to the following error :( . Any clue? BTW I did not have cython_utils inside /Tracking-with-darkflow/darkflow/ but inside /Tracking-with-darkflow/darkflow/darkflow/. I tried to move it both to /Tracking-with-darkflow/darkflow/ and to /Tracking-with-darkflow/ as suggested, to no avail

[tchuang96224]

I faced this error,
ImportError: Building module darkflow.cython_utils.nms failed: ["distutils.errors.CompileError: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit status 2\n"]
and I have no idea how to solve it. Anyone can help?

[buzdarbalooch]

@tonmoyborah i am also using python 2.7 facing the same problem. By chance were u able to resolve this issue.

[Sha-Shak]

did anyone solved this issue? I am having the exact same issue if any of you have solved it could you please tell me how to fix it?

Anybody solved this problem?
