Docker build issues with python and data science packages

Question

Relatively new to docker (building and creating) and I am running into an issue when I attempt to build a docker image with data science packages. The process seems to error out on python selection but I'm not sure why. I have my docker file (Dockerfile) in the directory root where I am attempting to build. It makes it through the build process to some degree and then fails:

Any ideas on why this might be failing?

Answer 1

1. It would nice if posted a valid Dockerfile
2. The error is: python (no such package), I would try to identify which package is missing using a process of elimination and then figure out why it's missing.
