Boss detour, here is a vegetable dog
A "module 'cv2.cv2' has no attribute 'face' "solution
Second module 'cv2' has no attribute 'gapi_wip_gst_GStr solution
A "module 'cv2.cv2' has no attribute 'face' "solution
This kind of problem occurs because after the update of the new version of opencv-python, many extension files of opencv-python need to be downloaded separately, instead of just one download and installation as before, the solution is given here.
1. Install the solution
pip install opencv-python //直接对cv库进行下载
pip install opencv-contrib-python // 对cv库的扩展文件进行下载However, the download through this path will respond very slowly or even report an error such as timeout. The safflower is very dazzling, so we can use the domestic mirror to speed up the download. Douban source is recommended here.
pip install opencv-contrib-python -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip install opencv-python -i http://pypi.douban.com/simple --trusted-host pypi.douban.comEnjoy blazing fast download speeds
2. Reloading method
Some friends responded, I downloaded it and it shows that I have downloaded it
In this case, I have all the libraries I want to download, but they still can’t run. This is really embarrassing for the blogger, but after many attempts, the blogger found that it only needs to be uninstalled and reinstalled . I don’t know why, but don’t dislike the blogger dish dog
pip uninstall opencv-contrib-python
pip uninstall opencv-python Use the above command to uninstall these two libraries, and then use the installation solution to re-download and use it
pip install opencv-contrib-python -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip install opencv-python -i http://pypi.douban.com/simple --trusted-host pypi.douban.comNext, everyone can "swipe" the downloaded code at a fast speed and run it successfully ! ! !
Second module 'cv2' has no attribute 'gapi_wip_gst_GStr solution
This problem is usually caused by the incompatibility of many versions after cv2 is updated. What we need is to restore the immature version that cannot be used to the mature version that can be used before. This command is recommended here
pip install opencv-python install "opencv-python-headless<4.3"The version will be replaced and the code will be ready to run.
