[Solved] Python OpenCV Error: Current thread is not the object’s thread

Hello Guys, How are you all? Hope You all Are Fine. Today I get the following error Python OpenCV Error: Current thread is not the object’s thread in python. So Here I am Explain to you all the possible solutions here.

Without wasting your time, Let’s start This Article to Solve This Error.

How Python OpenCV Error: Current thread is not the object’s thread Error Occurs?

Today I get the following error Python OpenCV Error: Current thread is not the object’s thread in python.

How To Solve Python OpenCV Error: Current thread is not the object’s thread Error ?

  1. How To Solve Python OpenCV Error: Current thread is not the object's thread Error ?

    To Solve Python OpenCV Error: Current thread is not the object's thread Error As noted already, the basis for this problem is discussed in opencv-python issue 46, and results from the duplication of the following libraries both on the host and the opencv-python distro libQtDBus libQtCore and libQtGui.

  2. Python OpenCV Error: Current thread is not the object's thread

    To Solve Python OpenCV Error: Current thread is not the object's thread Error As noted already, the basis for this problem is discussed in opencv-python issue 46, and results from the duplication of the following libraries both on the host and the opencv-python distro libQtDBus libQtCore and libQtGui.

Solution 1

As noted already, the basis for this problem is discussed in opencv-python issue 46, and results from the duplication of the following libraries both on the host and the opencv-python distro libQtDBus libQtCore and libQtGui.

It has been lately addressed in the newest release of opencv-python. It is not a fix to the source code, rather the fix is to force pip to compile the newly available source via

pip install --no-binary opencv-python opencv-python

This will cause opencv-python to use the same libraries as the host, so the conflict no longer exists.

Solution 2

According to this issue posted on the OpenCV GitHub, this is a known issue that the developer states is damn near impossible to fix. It is apparently caused by a conflict in any Qt installations on the system with the Qt that is shipped with OpenCV. There are some suggestions floating around to remove the libqt5x11extras5 package from the system. This may fix it for some but anyone running these libraries on a Linux distribution that uses a window manager based on Qt will render their desktop environment unusable by removing this package (having tried it myself).

You can try building OpenCV from source using the WITH_GTK=ON option when running cmake which will use GTK instead of Qt, circumventing the conflict. However, this is hard to make use of in Python when using virtual environments.
