[python]python-pcl在ubuntu下运行报错 poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost‘ failed.

问题：

[xcb] Unknown sequence number while processing queue [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. emacs: xcb_io.c:263: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.

解决方法：

sudo apt-get install libcanberra-gtk-module -y

apt-get install libx11-dev
