Might need to be installed. What distro/version are you running?

...for me: The docker file - uninstalled tensorflow because of Illegal instruction (core dumped) error and reinstalled version 1.5 of tensorflow. Maybe the dockerfile is not correct for building LJSpeech-1.1.
You should check out this!
