Ah my bad I hadn't released the better error printing in case of NaNs. But this will improve the error message only, the underlying problem here seems to be with NaN elements in the gradient no?

[gdalle]

It's interesting that it works on 1.7 though

[matbesancon]

maybe you are not reaching the point where the gradient evaluates to NaN? The RNG in Julia changed from 1.7 onwards if I recall

[gdalle]

Possibly. Not sure how to debug this though, the MWE is pretty involved

[matbesancon]

one ugly way would be to print the gradient at every iteration, or print the direction in the LMO itself

[matbesancon]

let's debug that between main dish and dessert next week
