Failed to open HDF5 files

Hi @Dalia. Thanks for reaching out about this.

We typically see the error

ERROR: Failed to open HDF5 file with mode ‘w’: summary.h5

because an openmc.StatePoint object is already open in the Python interpreter. We’re working on a way to avoid this issue, but for now I’ll refer you to this thread on the topic:

Along with an explanation of a couple ways to manage this issue:

As for the missing statepoint file you mentioned in your last post, I’m not really sure why that would occur without seeing the rest of your notebook. If you’re still running into problems after trying the solutions in the thread above, if you can share the notebook that would make it easier to diagnose that problem.

Hope this helps!
