Problem on the step to verify my installation

[AnaMBomfim]

Good afternoon,
I’m having the following problem when I try perform do the fourth step (avaible in “Quickstart” in https://finn.readthedocs.io/en/latest/getting_started.html) to start using the tool:

”Unable to find image 'de:latest' locally
docker: Error response from daemon: pull access denied for de, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.”

I saw that this discussion already existed, however there was no conclusion and it was closed.

How can I solve it?
