The procedure hit me with…

The configuring step of #tensorflow hit me with the problem

Problem with java installation: couldn’t find/access rt.jar in /opt/jdk-9

And the problem was that #bazel and #jdk-9 are having some issues together it seems. So, I had to remove #jdk-9 by this

sudo apt-get purge openjdk-9* 
sudo apt-get purge oracle-java9-installer 
sudo add-apt-repository --remove ppa:webupd8team/java

and install #jdk-8 by these

sudo apt-get install openjdk-8* 
sudo apt-get install maven maven*

Hopefully it works now!!
*fingers crossed*
