I am facing the same problem. Did you figure out the solution?

This problem was solved by downgrading the cjon version as mentioned here: https://github.com/mpx/lua-cjson/issues/56#issuecomment-394764240

Hey, Check this docker image I created for running dense cap in gpu! https://hub.docker.com/r/jainal09/densecap_gpu

For Cpu version. Use this docker file. https://github.com/runwayml/alpha_models/blob/master/densecap/Dockerfile
