Hi everyone,

my compas\_fofin-UI keep showing this Error if I’m trying to use fofin\_attribute or update\_xyz  
I’ve tried restart my Proxy server, reinstall compas\_fofin and compas\_fofin-UI but nothing seems to work…  
I also checked the dev folder all the cmd.py is there… so…

Is there any way to fix this?

Thanks

Finn

hi finn,

there have been quite a few changes recently and the error you see is caused by those changes.

- `compas_fofin-UI` has been integrated into `compas_fofin`
- COMPAS has a new system for making Rhino Command Menus and the dict error is a result of that
- installation of Python CommandPlugin UIs has been simplified in recent COMPAS versions
- the commands of the UI have been split up into simpler parts.

i would recommend to delete you current `fofin` environment and start from scratch following the `Getting Started ` instructions in the docs: [https://blockresearchgroup.github.io/compas\_fofin/gettingstarted.html](https://blockresearchgroup.github.io/compas_fofin/gettingstarted.html)

you will be the first using the new setup, so there might be a small hickup here and there 🙂  
please report back or post issues and i will try to smoothen things out as needed…

best,  
tom

Hi Tom,

Thank you!  
I update my compas\_fofin and everything works fine until I try to use FOFIN\_update\_xyz

I’ve tried to restart my Proxy server but still showing me this ERROR

am I not install it successfully?

Thank you again,

Finn

the latest released version of COMPAS is lagging behind a bit, so perhaps you should install COMPAS from source as well.

```bash
cd path/to/compas
pip install -e .

```
