Run_Depletion.py did not deplete

I tried running the run_depletion.py program from the exemple folder on my computer with openmc version 0.14.0. After I saw the results, no depletion calculations occurred and the material did not change. I have run this code on another computer but it successfully shows the depletion process. What actually happened so that the depletion calculation did not occur?

Figure_3
Figure_2

Did you designate the material(fuel) “xx.depletable=true” and give the volume of these depletable materials?

I met this false long time ago, and I forgot how I worked out, so my question above may be wrong.

I have solved this problem by adjusting the scipy version. More details can be seen in the discussion topic at this link
