opencv error when running demo.py

[sangthian]

after running python demo.py, an error occur.

I install all the packages in anaconda's pytorch env. my opencv is 2.4.10( conda install opencv=2.4.10)

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 -------src-dir-------/opencv-2.4.10/modules/highgui/src/window.cpp, line 501

I also have the same error message on running demo.py.

I use Ubuntu 16.04 and installed opencv via pip install opencv-python.

@tegg89 @Jmx5200 This has nothing to do with YOLO2-Pytorch. You should re-install opencv package. It works well for me.

conda remove opencv
conda update conda
conda install --channel menpo opencv

conda install --channel menpo opencv doesn't work for me. But pip install opencv-python works.
