Internal data stream error

安装运行官方案例持续报同一个错误:


以下为jetpack版本

python=3.8.10
deepstream=6.1
ubuntu=20.04

You need to set DISPLAY if you run from remote, or you can run directly from desktop.

When I set “export DISPLAY=:0.0” and run my code,I got other errors:
“nvbufsurftransform: Could not get EGL display connection”
“No protocol specified”
How can I solve that?
Thank you!

Can you get the display?
