Could you provide more info on your environment? Such as your opencv version

[LuZeking]

environment：Python 3.6.8 GCC 7.3.0 opencv4.1.0

[liushuchun]

the same issue.

[rogerwwww]

Hi @LuZeking, your issue seems a different one. Please refer to the new issue here.

[txytju]

My opencv version is 3.4.3

[universea]

遇到同样的问题，ubuntu18.04 python 3.5

[Simon-LLong]

Firstly, you should clone https://github.com/GothicAi/cython-global-matting.git

Then modify setup.py line 9,10,11 libs = os.popen('ldconfig -p | grep libopencv') libs = libs.readlines() lib_paths = [l.split('=>')[-1].strip('\n').strip(' ') for l in libs]

Opencv lib path is not /usr/lib in some user's environment, maybe in /usr/local/lib, So the lib_paths is []. You should find your opencv lib path to correct the lib_paths.

Secondly, Set LD_LIBRARY_PATH={your opencv lib path} in your bash.

Lastly, you should modify line 37, modify opencv2 path according to their own environment, maybe /usr/local/opencv2, then run python setup.py install

[Fang-Haoshu]

Thanks, folks! We are currently looking into this issue and will update the pip package these days. Sorry for any inconvenience.

[GothicAi]

Hi! These problem may be caused by our opencv-mat package. If you do not have opencv(c++ version, not opencv-python) in our default path, or your OpenCV version is 3.x or above, errors may occur.

We have updated opencv-mat package version 0.1.3 on PyPI and this may solve the path problem. Our code can automatically search opencv source files and libs instead of using default path.

However, we are still working on the version problem. We recommend users to use python3.5 or 3.6 and OpenCV 2.x to avoid some errors for opencv-mat==0.1.3. We show some instructions here to help users to install OpenCV 2.x.

Sorry for these errors, and thank you for your affirmation of our work.

Something is still missing while installing opencv-mat

It looks like that your opencv_libs path is wrong. you should correct opencv_libs path like installing opencv-mat

@LL-Lee

I followed your guide of conda, just like this

and I think setup scripts can find opencv automatically

environment：Python 3.6.8 GCC 7.3.0 opencv4.1.0

I meet the same issue as you.Have you saved this issue yet?Can you tell me how to save this issue?Thanks.

Try to downgrade the opencv to version 2.0 just like described here

[BrookXuan]

I have solve this issue in the following way.First,i download opencv_mat-0.1.3.tar.gz and unzip it.Then i add opencv2 folder which is copied from /home/brook/anaconda3/envs/py36/include in the unziped opencv_mat-0.1.3 floder.And my opencv version is opencv-nopython _2.4.9 _salilab.At last,i zip opencv_mat-0.1.3 and use pip installing it. Although,i have solve the isssue in this way, i still don't know whether it will work normally.

@BrookXuan Thanks for your suggestion! We will investigate it.

@rogerwwww I have already used conda to set enviroment which is include opencv-nopython, cython numpy, opencv-mat and instaboost.But when i try to import instaboost, i met this issue.

ImportError: /home/brook/anaconda3/envs/py36/lib/python3.6/site-packages/opencv_mat.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN2cv9ExceptionC1EiRKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEES8_S8_i

Do you have any idear to save this problam?

I have meet this problem, have you solved it?

[rogerwwww]

For those who have successfully compiled but meet errors like "ImportError: undefined symbol":

We have met a similar situation (once) on our machine and it is probably caused by incorrect dynamic linking. You may try settingLD_LIBRARY_PATH but the underlying reason differs among environments, and we have not found a universal cure to all this kind of issues.

Currently, we are still struggling to solve the dependency problem among heterogeneous environments (this seems a universal problem for all CPP projects). We are sorry about the inconvenience, and, as always, any suggestion is welcomed. Thank you all!

I have saved this problam by installing opencv-3.4.7 in system (https://github.com/GothicAi/cython-global-matting). It takes me a lot of time to do that.And except the author's way,there are many articles in the wed teaching you how to install opencv3 in ubuntu16.04. Thanks author‘s share,i have integrated instaBoost into my mxnet.

It is great! Can you share your settings ? I got the errors:
from opencv_mat import global_matting, guided_filter ImportError: /usr/lib/x86_64-linux-gnu/libQt5OpenGL.so.5: undefined symbol: _Z12qTriangulateRK11QVectorPathRK10QTransformd

I don't know how to fix it. : (

I don't know how that happens.Maybe,your system is lack of this lib.In the same path,i find libQt5OpenGL.so.5 in my system.

Yes, I had the libQt5OpenGL.so.5 too. When I run the yolack's train.py ,it is ok. But when I run the mmdetection's train.py, I got this error. Do you try mmdetection's train.py?
