Questions about 'Parallel Execution'

[JiajunDu-ReSustain]

Dear UQpy developers,
Thanks for your excellent work to give us such a wonderful python package to do UQ-related work in research.

Recently, I hope to use this package to do some research on the Surrogate model and Sensitivity analysis for seismic resilience assessment, but I encountered some problems in this process of learning and would like to ask you.

When I am running a simple case in the help document you provided, such as 'RunModel Examples'-'Python'-'Example 1.2: Pass samples as list, Python function called, parallel execution'. I cannot correctly run it. The error is "FileNotFoundError: [Errno 2] No such file or directory: 'qoi.pkl'". It seems like the parallel execution is wrong running. But i have already install the 'mpi4py' in my environment. When i change the ntask from 2 to 1, i obtained the result. The attachment is my jupyter notebook file.

So would you like to give me some help?

Regards,

Jason
