Local Demo is not working

[dkbs12]

Hello,
When I try Local Demo in my colab, I faced the error.
After inputting as same as written in above site, I found the error message as "Can't find a suitable configuration file in this directory or any parent. Are you in the right directory? Supported filenames: docker-compose.yml, docker-compose.yaml"
And the code that I input was as below;

!cd haystack
!docker-compose pull
!docker-compose up

I guess there is something wrong with the configuration file in the github.
I'd like you to help me with this.
Thanks.

I'm fairly confident it's not possible to run the local demo in Colab. You should try on your local machine.
