Is it possible for you to obtain the full stack trace so we can see where rand is called?

I highly suspect this to be caused by constraints in the simulation that causes all individuals to be discarded.. does this seem right here?

Aneoshun avatar Aneoshun commented on July 22, 2024

Hi @AranBSmith,
Yes, your hypothesis could be the cause of this issue. Can you change some of your constraints to check this?

AranBSmith avatar AranBSmith commented on July 22, 2024

Yes, I did have a bad constraint which eliminated the majority of individuals, after easing the constraint this assertion does not fail.

Glad to hear this. We might want to check this earlier in the code and print a userfriendly message to avoid people to face the same problem
