我正在尝试使用pycharms从我的桌面远程运行一个opencv项目。我像这样设置远程解释器：enter image description here enter image description here
当我尝试运行脚本以打开带有摄像机实时供稿的窗口时，
export DISPLAY=":0";有什么想法吗？
编辑----- 我正在Windows 10上使用vnc viewer来远程访问树莓派，并使用pycharm内置的ssh连接和同步文件。
EDIT2 ------
我在控制台中运行了ssh://pi@192.168.50.224:22/home/pi/.virtualenvs/cv/bin/python -u /home/pi/opencv_projects/tmp/pycharm_project_255/uvc_cam_feed_demo.py
Unable to init server: Could not connect: Connection refused
(Color Frame:1267): Gtk-WARNING **: cannot open display:
Process finished with exit code 1
，但在pycharms中仍然出现相同的错误，
