Openmc.run() provides Error

Hello,
I have install openmc in google Collab environment from github using the command " pip install git+ github link of opemmce". I have tried to test an example(BWR) that are available in openmc. All the portion of code has executed properly. But openmc.run() is not working. The following error are appeared in my screen. Someone please tell me what is the problem? how I can solve this.

@Simul.Hasan120 Welcome to the community. How did you install openmc in Colab? FYI, pip install git+ github link only install the Python packages of openmc.

I will give you a quick way to install openmc in Google Colab using miniconda.

! pip install condacolab
import condacolab
condacolab.install_miniconda()
! conda install openmc -c conda-forge -y

! wget -O - https://anl.box.com/shared/static/9igk353zpy8fn9ttvtrqgzvw1vtejoz6.xz | tar -C /content/ -xJ
import os
os.environ['OPENMC_CROSS_SECTIONS'] = "/content/endfb71_hdf5/cross_sections.xml"
