Hi,

Installed “prodigy-1.5.1-cp35.cp36-cp35m.cp36m-linux\_x86\_64.whl” on ubuntu 18.04.

When I am trying to invoke prodigy url to annotate, facing the below error.  
Internal Server Error

Never mind.

This is working for me by changing versions as  
falcon==1.4.1  
hug==2.4.1  
thinc==6.10.3  
spacy==2.0.12  
prodigy==1.5.1

Thanks,  
ramesh.

Thanks for updating with your solution! I think this might be related to an update to Hug or conflicting dependency versions. I’ll have a look to see if there’s anything we need to pin more strictly / explicitly for the next release.

RAMESH THANK YOU SO MUCH! We were banging our heads against the wall the past day wondering why suddenly things stopped working.
