Error in Plot

When I try to plot in Jupyter Notebook

root_universe.plot show following error
see

  1. [ root_universe 1.png ]
  2. [ root_universe 2.png ]

Why this kind of error?

I believe this is due to a bug that has since been fixed in the developmental version of OpenMC. When I run your notebook (using the developmental version), the plot of the universe works fine. We will be making a new release very soon, so once that it out, I would recommend you to upgrade your version.

Thank you for your reply sir.
The same code runs successfully in my friends laptop ( version 0.10).For fixing this error, i update Notebook, reinstall openmc . But same error comes every time

Sir,
Now root universe in plotting mode is successfully run in Notebook.
After getting your reply, I reinstall Anaconda and OpenMC.
