free(): invalid pointer Aborted (core dumped)

[pandsia2007]

When I run the codes of 'Training' block and 'Invertible Interpretation Networks' block, I always get a 'free(): invalid pointer Aborted (core dumped)' error in the line of ' iterator = get_obj_from_str(config["iterator"])'(in edflow/main). But I run the codes of 'Classifer' blocks, the error disapeared.

I am very confused about this error and look forward to your answer!
Best!
