Hi @piaoya,
I spent a lot of time on it, I think this code is not build with the latest version of fastai.
Yes, this code was built with fastai==1.0.22 as specified in the floyd_requirements.txt file
I ended up with a model which was built, but most of the time when I followed the service-link as provided in 'me/projects/projectname/versionx'-Folder I just got: '502 Bad Gateway - nginx'.
I've quickly checked your last Model API and I spotted this error in the logs (unfortunately the Model API logs are a bit hard to read since there are 2 processes who are logging there):

It seems a typo in the path to the pth file, it should be /floyd/home/clabby-classifier/models/wildkraut-stage-2.pth.
Hope that helps.
