While running easyvvuq_fusion_tutorial.py, an assertion failure occurs:

I haven't fixed the real underlying problem which arises from an assertion error in code from @goghino , but by wrapping the failing code in a try/except structure the analysis will succeed even though the "Sensitivity Analysis: Derivative based" code fails.

For some value of T,
Y_hat[t].names <> Vars

Unless @goghino wants to look into the problem, I suggest we close this issue ...
