Python 使用opencv读取图像

我试图运行一个眼睛状态检测的演示项目，我得到了以下错误

    python -m demo --process image --path /home/samuel/Pictures/download.jpeg --json_path /home/samuel/EyeStateDetection/models/model.json --weights /home/samuel/EyeStateDetection/models/model.h5

错误出现在

cv2.imshow（“图像”，img）

您没有安装GTK。GTK负责在使用

imshow（）

时显示图像界面。如果您正在运行Ubuntu，请使用

sudo apt-get install libgtk-3-dev

有关OpenCV的完整安装说明，请参阅

另外，如果要使用

imshow（）

，还需要使用

cv2.waitKey（）

sudo apt-get install libgtk-3-dev
