Spyder can't save variable values from variable explorer #20912

Closed sasasa966 closed 1 year ago

sasasa966 commented 1 year ago

Description

What steps will reproduce the problem?

Create a pyomo optimization model Create a class V to store values as V.Value Run model an save results in the V structure Save results from spyder variable explorer Spyder has encountered and internal error and system crashes

Might be that it can't save pyomo variables, models, or constraint structures (not values, but the structure created by Pyomo)

Hi @sasasa966 thank you for the feedback! This seems like a duplicate of https://github.com/spyder-ide/spyder/issues/17199 Seems like some variables could take more time to be processed than expected and then the error you got is thrown.

Let us know if the info in the issue linked above helps!
