ImportError: cannot import name FIFOCache

Hi everyone; I installed the latest prodigy version 1.11.7 inside a conda environment, Linux x86-x64 & python 3.7.3 and I cant start the server anymore, it is showing me this error message:

Hi! Could you run pip list and check which version of cachetools you ended up with in your environment?

Hi @ines, I have cachetools==4.0.0

Are you able to upgrade to cachetools==5.0.0?
