Installing opencv-python

[AvielNiego]

Hey,

Is there a way to install opencv-python? The standard pip3 install opencv-python returns

Could not find version that satisfies the requirement opencv-python (from versions: )
No matching distribution found for opencv-python

[HsuTouhuan]

@HsuTouhuan Have you run pkg upgrade ?

thanks a lot ,it used ٩( 'ω' )و .but also the errors appeared just like upstirs.i'm solving them

[HsuTouhuan]

There are 2 python libs in the boost package /data/data/com.termux/files/usr/lib/libboost_python36.so /data/data/com.termux/files/usr/lib/libboost_python27.so If you are using python 3 either create a symlink ln -s /data/data/com.termux/files/usr/lib/libboost_python36.so /data/data/com.termux/files/usr/lib/libboost_python.so It should link against libboost_python36.so when you build.

eee.could you tell me the operation abou this step？thanks

[ghost]

Why you have /data/data/com.termux/files/usr/lib/libboost_python36.so ? We have python v3.7 for now, so it should be /data/data/com.termux/files/usr/lib/libboost_python37.so.

thank you.and i just reply from upstirs.my problem is i don't know how to realize them

[yangxin0]

That's right, it was the opencv version. The last one from github releases it's working perfectly. Maybe, a disclosure about versions has to be added to the wiki. Thanks for the support. Ismael

hi isman7, which version do you use?

[wahyubram82]

tooks a days for me to successfully instal opencv on termux.

the last step that giving success build is:

1. delete build folder

2. mkdir build

3. cd build

4. run cmake with: LDFLAGS=" -llog -lpython3" cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=$PREFIX -DBUILD_opencv_python3=on -DBUILD_opencv_python2=off -DBUILD_opencv_python2=off -DOPENCV_EXTRA_MODULES_PATH=/data/data/com.termux/files/home/opencv_contrib/modules -DOPENCV_ENABLE_NONFREE:BOOL=ON -DWITH_QT=OFF -DWITH_GTK=OFF -D WITH_TEST=OFF -D BUILD_TESTS=OFF -D BUILD_EXAMPLES=OFF ..

5. then run: ccmake .

you will see a sort of cmake option visually, I made mine like below:

Termux on Samsung Galaxy Tab 5Se

this is a good explanation, i will try it on my tab s5e as well

[vetmiker]

When I follow the compiling instructions listed in the wiki, and the process in the above post, I get the following error message after I run python import cv2:

ImportError: ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.

In looking at OpenCV, it appears this could be due to python binding linking: https://github.com/opencv/opencv/issues/13202

I'm thinking this is due to how things are stored in Termux, but I'm not familiar enough with how things are structured to do a really good job troubleshooting this.

Thoughts?

[its-pointless]

I have opencv working installed via apt. Just add my repo.

[vetmiker]

@its-pointless just grabbed your repo and installed - works perfectly. Thankyou!!

[hyankov]

Total Linux noob here. Can anyone elaborate how to get the package to install, in terms of commands? And no rm -rf pls

[tathastu871]

Close the issue. its solved by adding its pointless repo and installing using apt install opencv

[yousufcodes786]

I have opencv working installed via apt. Just add my repo.

Can you tell the steps To install your pointless repo.. I am struggling to install opencv for a month in termux

[ghost]

Can you tell the steps To install your pointless repo..

https://wiki.termux.com/wiki/Package_Management#Community_repositories

[fahadali32]

I am doing install like this .. pkg install opencv but it show's me error

[ghost]

Proper pkg install:

curl -LO https://its-pointless.github.io/setup-pointless-repo.sh
bash setup-pointless-repo.sh
pkg install opencv

If trouble with setting up third-party repo, then manually download debs. Pick a one appropriate for your CPU arch:

• https://github.com/its-pointless/its-pointless.github.io/raw/master/files/24/dists/termux/extras/binary-aarch64/opencv_4.2.0_aarch64.deb

ImportError: dlopen failed: cannot locate symbol "_ZN6google8protobuf8internal14AddDescriptorsEPNS1_15DescriptorTableEPKPFvvEi"

Then @its-pointless should rebuild it.

i meet this question!!

[Lunah12345]

me too, I have this problem when i try to show frames with the same function

[tathastu871]

I have opencv working installed via apt. Just add my repo.

You have but what about opencv contrib and extra modules. They were not in your repo. So they needed to be build while building opencv And if we install opencv from your repo then we can't use them and we need to build from scratch. keeping both build will cause conflicts.

Please if possible add extra modules to your apt repo

[tathastu871]

I ran into following errors while compiling opncv and extra modules Commands used

LDFLAGS=" -llog -lpython3" cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=$PREFIX -DBUILD_opencv_python3=on -DBUILD_opencv_python2=off -DBUILD_opencv_python2=off -DOPENCV_EXTRA_MODULES_PATH=/data/data/com.termux/files/home/opencv_contrib/modules -DOPENCV_ENABLE_NONFREE:BOOL=ON -DWITH_QT=OFF -DWITH_GTK=OFF -D WITH_TEST=OFF -D BUILD_TESTS=OFF -DBUILD_EXAMPLES=ON

Solved above error with python3 setup.py develop But then another error came while importing which was

[tathastu871]

When I follow the compiling instructions listed in the wiki, and the process in the above post, I get the following error message after I run python import cv2:

ImportError: ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.

In looking at OpenCV, it appears this could be due to python binding linking: opencv/opencv#13202

I'm thinking this is due to how things are stored in Termux, but I'm not familiar enough with how things are structured to do a really good job troubleshooting this.

Thoughts?

in build directory go to modules folder and python3 setup.py develop It will solve this error

[sambit9876]

Hi, Total noob here,I have set up @its-pointless repo but after installing opencv I get the below error.

(Version verification failed in "modules/dnn/opencv-caffe.pb.cc".) terminating with uncaught exception of type google::protobuf::FatalException: This program was compiled against version 3.12.2 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.13.0).

(Version verification failed in "modules/dnn/opencv-caffe.pb.cc".) Aborted

I tried setting up protobuf 3.12.2 but that didn't do anything. Do I have to build it from source again?

[tathastu871]

I succesfully compiled build and installed opencv from source without any error. But import opencv works only in $HOME and not anywhere else. Also it seems that opencv actually not installed, because no modules whether imread, imageio nothing works it keeps saying no attribute.

Also

import opencv as cv2
cv2

Above command show

<module 'opencv' (namespace)>

No init.py there and hence complete installation is non functional.

While compiling i added python3 support but fails to work

But after cmake make and make install steps i goto opencv/modules/python folder and ran python3 setup.py install and it finally installed but then below error occured

Hi, I am also getting the same message like @ABIRHOSSAIN10 @Yisus7u7 python version is 3.10.0 my device is Samsung Galaxy S8 (exynos) I have performed following steps:

curl -LO https://its-pointless.github.io/setup-pointless-repo.sh
bash setup-pointless-repo.sh
pkg install opencv

as a regular user (not a root)

edit: now i get it, the its-pointless repo contains opencv for python 3.9, but the lastest is 3.10 and this one is present in temrux repo

edit: now i get it, the its-pointless repo contains opencv for python 3.9, but the lastest is 3.10 and this one is present in temrux repo

may I ask how you downgrade python version from 3.10 to 3.9? because I also python 3.10 and want to try. By the way actually starting I install python 3.9.7 but when I bash setup-pointless-repo.sh then it automatic upgrade my python to 3.10...

[SamYokai]

Sorry for asking, I would like to ask that actually how to install opencv in termux which can python import and use? because I follow the step which curl the its-pointless repo and bash then pkg install but only in pkg list and haven't in pip list. I also try other method which had found from previous comment but still not working. But I use same way to install numpy and scipy no problem, both of these can found in pip list, just except opencv. Anyone can help me? Im using Android 7.1.1, Termux 0.115, Python 3.9.7

[maklimcz]

Hi, I did not manage to install opencv. The building it from sources was failing and I couldn't solve that. Since then I haven't looked if sth changed.

[SamYokai]

Hi, I did not manage to install opencv. The building it from sources was failing and I couldn't solve that. Since then I haven't looked if sth changed.

oh I see, never my its ok, now I also face the problem, but for your problem I think you can try with Python 3.9 except from 3.10 since for what I know this repo the latest is Python 3.9 and haven't yet prepare for Python 3.10. But my problem is more make me curious, haha, since I using Python 3.9 and I try install for numpy, scipy and opencv since these three can get and use same method with the its-pointless-repo, then what I get is numpy and scipy can succes found in pip list and python import also no problem, but only opencv cannot be found in python. This problem make me curious to myself. haha

[maklimcz]

Please let me know if you manage to run python and opencv to use device camera (preferably without root)
