breeze kvstore topology does not work about openr

[saifhhasan]

Can you install matplotlib and run breeze kvstore topology ?

Reason for this error message is that we don't want to enforce matplotlib to be a hard dependency of breeze tool (as it is very big library). Hence we made it soft dependency

You don't need to rebuild anything. Just install matplotlib and run command again. I will change message to be more specific. Let me know if it works for you.

sudo apt-get install python-matplotlib

commit e4d9ff3#diff-304d33f4448afe5d095ce2e660da325b add better error description of how to fix it. Closing the task.

Thanks, I understood the reason why matplotlib was not installed. The better error description sounds good.
But my environment, the topology command cannot work after installing matplotlib...

Drawing topology requires `matplotlib` and `networkx` libraries. You can install them with following command and retry. 
  pip install matplotlib
  pip install networkx
root@u6:~/openr/build# pip install matplotlib

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

And I try the command after apt install python-matplotlib, then a different error has come.

I imagine that a reason of the issue is that my enviroment is only CUI (not GUI)...
Many thanks.
