Unable to init server: Could not connect: Connection refused

 

环境：pycharm ubuntu linux 远程开发环境

报错：

Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused

(frame:25170): Gtk-WARNING **: cannot open display: 

Process finished with exit code 1

原因：

你的代码中可能使用了cv2.imshow等类似的需要调用图形界面显示的

但是因为是在远程服务器上运行，可能不支持显示图形界面。去掉即可
