janza / docker-python3-opencv Goto Github PK

Can we rename the docker image?

If we use this name (jjanzic/python3-opencv) would be more appropriate,
Instead of using this name (jjanzic/docker-python3-opencv).

And also tags.

• Current Tags
  • opencv-4.0.0
  • contrib-opencv-4.0.0
• New Tags
  • 4.0.0
  • 4.0.0-contrib

Usage

$ # Current
$ docker container run -it jjanzic/docker-python3-opencv:opencv-4.0.0 python
$ docker container run -it jjanzic/docker-python3-opencv:contrib-opencv-4.0.0 python
$ # New
$ docker container run -it jjanzic/python3-opencv:4.0.0 python
$ docker container run -it jjanzic/python3-opencv:4.0.0-contrib python

Dear janza, i have this error:

error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvNamedWindow

When use things with windows, what can i do please?

Upon trying to build the image, with:
docker build -t 'opencv' .

I get E: Unable to locate package libjasper-dev

according to:
https://stackoverflow.com/questions/43484357/opencv-in-ubuntu-17-04/44488374#44488374
one should add some repository. This solution did not work for me.

Request for a new build with latest opencv-python and opencv-contrib-python which includes SIFT in xfeatures2d.

the simbolic link to the cv python library should point to the installed python version, so if you use python3.9 it should be:

    RUN ln -s \
    /usr/local/python/cv2/python-3.9/cv2.cpython-39m-x86_64-linux-gnu.so \
    /usr/local/lib/python3.8/site-packages/cv2.so

However, this hard fix is no longer needed (at least with recent cmake and latest opencv version)

Greeting,

I ran this Dockerfile on my unbuntu VM, with a minor change in the first line as "from python". After it's done I tried import cv2, but got

>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'cv2'

Do I miss anything? Thanks,

Chun-Yen

We've been using your docker image for our testing and noticed our code started failing today on automated builds due to the upgrade.

We reverted to contrib-opencv-3.4.1 but that has an older version of cmake.

Can you release a version of contrib which was pushed 3 months ago in August?

I would be nice if you could give the opencv build information for each image with:

python3 -c "import cv2; print(cv2.getBuildInformation())"

To use OpenCV 4.0.1 instead of 4.0.0, is it just a matter of changing the OPENCV_VERSION variable?

I could submit a pull request.

Thanks.

Hi,
I think these tags doesn't work correctly.

tags: opencv-4.0.0, contrib-opencv-4.0.0

Thanks gorogoroyasu for this pull request.
The solution worked for me.

Opencv 3.4.1 was only tagged with contrib.

unzip: cannot find zipfile directory in one of 3.4.0.zip or 3.4.0.zip.zip, and cannot find 3.4.0.zip.ZIP, period.

OpenCV is giving a warning that this option is deprecated:

-- WARNING: Option ENABLE_AVX='ON' is deprecated and should not be used anymore
--          Behaviour of this option is not backward compatible
--          Refer to 'CPU_BASELINE'/'CPU_DISPATCH' CMake options documentation

I tried myself and couldn't get it working. The jasper lib has issues and I didn't get too far

How to use imshow from inside container?

I am getting the following error:
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvShowImage, file /opencv-3.4.0/modules/highgui/src/window.cpp, line 611

Attempting to run camodet_python I get:

OpenCv version: 4.1.1

  File "/app.py", line 300, in <module>

If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvWaitKey'

Taking the suggestion of installing libgtk2.0-dev and pkg-config before the cmake fixes it. The waitKey still doesn't actually work, and I don't really need it, but this doesn't seem like a bad additiion to your image anyway.

When I set the same configure of you,there is an error about downloading the file ippicv_linux_20151201.tgz. Could you push the file to the github?

maybe this is a very silly question. I think docker can't have GUI. so any gui related function should not work with this docker image?

How to fix this error message?

in the docker hub page it says the tag opencv-4.1.0 is present in the documentation, but looking at the available tags I cannot find it, think you may have accidentally only released it as latest. see https://hub.docker.com/r/jjanzic/docker-python3-opencv/builds
