Hi, When I tried to use third grasshopper example of Compas singular. I have windows firewall massage. ![image](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/01b02a937a12b8b0928af8ea69c40f6daf9218fe.jpeg) then I tried to fix it from the control panel and allow python. ![image](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/4e5295797320e79df0aac619ef36dcb765ab3ea7.png) But that file didn’t work again. ![image](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/2164e756c1e77cf0ee2e4912199fccb4b20be06c.jpeg) I think the problem is that. it doesn’t know surface\_guid in “gh\_surface\_decompesition” ---

Hi, I have installed compass and compass- singular. I want to use the codes are in associated page of compass such this and see the similar result on Rhino screen. such as your example. for trying them I need python or C++ in grasshopper. I checked in python but they not work. I need maybe the name of plugins to add them in starting point of codes. ![image](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/48fd29a5c0b5397977bba0d76db0648305313986.png) ---

Have you linked compas\_singular to rhino/gh? Maybe you can try running python -m compas\_rhino.install -p compas\_singular in your anaconda prompt from the environment you have compas and compas\_singular installed. ---

Well now it looks like the issue is with compas\_rhino because it can’t find the selectors module in compas\_rhino.objects. I’m not sure but it can be that compas\_singular depends on a different version of compas than what you have installed and linked to rhino. Maybe you want to double check that. ---

`compas_singular` requires a bit of updating but the main author/developer is on vacation. you will have to be patient for a few more weeks until these things can be sorted out…
