问题

conda环境中，遇到opencv的一个错误

Traceback (most recent call last):
  File "x01export_FasterRCNN_onnx.py", line 30, in <module>
    cv2.imshow("win", image)
cv2.error: OpenCV(4.6.0) /io/opencv/modules/highgui/src/window.cpp:1267: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

解决方法

pip install opencv-contrib-python -i https://pypi.tuna.tsinghua.edu.cn/simple

完
