What version of system are you using, Windows/Linux ? And check the version of open3d in your environment.

If you are executing the project in a python environment on a remote server, then the problem is caused by the lack of a monitor on your server.

[hitbuyi]

I have the same problem in Windows 11， add

import os
os.environ['DISPLAY'] = '1'

to solve it

[861482002]

  loc ：\mmdet3d\visualization\local_visualizer.py
    if os.environ.get('DISPLAY', None) is not None and show:
        o3d_vis.create_window()
        self.view_control = o3d_vis.get_view_control()
    return o3d_vis

我也遇到了这个问题，是因为这段代码，会判断你的环境变量中有没有'DISPLAY'，添加环境变量就行了 import os os.environ['DISPLAY'] = '1'，或者任何其他的字符串都行 就能解决
