Hi @edichief! @cbensimon might be able to help you a bit here, but let me provide some tips. You can click in “build error” to see all the logs, although in this case it might not be super useful. I’m not sure which is the exact OS being used, but it’s linux based.
In my local Ubuntu computer, doing pip install -r requirements.txt in a new environment with your requirements give me exactly the same error.
