Bug: Can't use DecisionThresholdConvergence object

[izagorac]

When I try to run the generate_counterfactual function in parallel as shown in the image below, I get an error about the Convergence object.

Code:

Error:

When I follow the stacktrace of the error it leads me to the get_convergence_type function in the Convergence module in the CounterfactualExplanations package. This function has 2 versions: one with AbstractConvergence as input and one with Symbol as input (see image below)

In my case, because I have created my own DecisionThresholdConvergence object, I would expect the first function to be called. However, for reason currently unknown to me, when the @with_parallelizer macro is used the function with the Symbol as input is being called. I've tested the same code without the macro and this works how it is supposed to.

@pat-alt is this enough information for someone to look into? If more details are necessary, please let me know. Solving this issue would really help me out :)

That's all I need and indeed a nasty little bug. I'm working on it, but metaprogramming is always a little tricky (at least for me). In the meantime, you should be able to use the parallelize function directly, instead of the macro.

Thanks @pat-alt, this fixes the issue
