Looks like you're missing a core file within the nbconvert package. Please try to update or uninstall/install nbconvert such that the missing file is restored. Should the problem persist, get the version of nbconvert you're using, along with other pertinent information (tracebacks are always welcome), and open an issue in the nbconvert repo. Thank you.
