On linux with Python 3.11 I got this error messages at ComfyUI's startup:

please use this command to check if your system has a correct display environment :
echo $DISPLAY
or,
env | grep DISPLAY

Hi,

it's empty. I use an LXC container without graphical interface to host my ComfyUI environment.
I will test in an other environment.

I tested on my Ubuntu, it shows :0, that means I have a display environment. it can be load, but there is another problem when I run the node. It seems like some requirements should be downgrade.
BTW, I am not a coder, I made this node by GPT, so I couldn't give you too much advise, sorry 😭
