[help needed] Cross Section Configuration Error

[Brian_Chen]

I have successfully installed OpenMC with relative ease. However, I have come to trouble in Cross-Section Configuration. I have tried following the steps from the tab https://openmc.readthedocs.io/en/stable/usersguide/cross_sections.html . I tried inputting

openmc-get-nndc-data

or any other codes that tab has provided into the Ubuntu bash terminal. However, it was stuck halfway with an error message

File “/home/[user name]/anaconda3/lib/python3.5/site-packages/matplotlib/backends/qt_compat.py”, line 158, in
raise ImportError(“Failed to import any qt binding”)
ImportError: Failed to import any qt binding

Am I missing something that leads to this error? Or is there a possibility that OpenMC on my laptop is not correctly installed?

Sincerely,

Hi Brian,

It looks like this is a problem with the installation of matplotlib, which is one of our third-party Python package dependencies. Take a look at this stack overflow page for possible solutions.

Best regards,
Paul
