Spyder 3 can't inspect values through the variable explorer while debugging

When I debug a script using IPython console in spyder 3.0.0, I can see my variables listed in the variable explorer but when I try to inspect any variable there is an error message pops up. I think inspecting variables (especially DataFrame) while debugging was doable in spyder 2.3.8. I also tried debugging in Python console and there was no error message and I can check (double click) any variable through the variable explorer.

What steps will reproduce the problem? The attached screenshot shows my script file and the error message.

Please provide any additional information below

I completely agree with @AndyCash1. Sure it is always a good idea to fix issues but not at the expense of removing one of the most important tools for debugging.

I understand this question has been answered, but this issue is a show stopper for me. The ability to easily inspect and visualize variables like dictionaries and dataframes while debugging is the main reason why I use the Spyder IDE over others. Thus, I will continue to use Spyder 2.3.9 for now.

I would be curious to understand the logic behind this decision, and what the timeframe for it’s implementation in Spyder 3.X is. Thank you.
