Cannot open objects in variable explorer

Description

What steps will reproduce the problem?

1. Define a class in another file

2. In a new file import the class file

3. create an object with that class

4. run the code. The code runs fine

5. try to explore the newly created object and get the following message

Spyder was unable to retrieve the value of this variable from the console.

The error message was: ‘tuple’ object has no attribute ‘raise_error’

1. The object is not a tuple. Indeed the value is " XXX object of YYYY module"

This is not related only to a single script. As I tried to create mock files and scripts but the problem persists.

Regards.

@PedroMat8 You should wait for the next release of Spyder, or installing it from source. The fix won’t let you open the objects in the variable explorer as spyder won’t know where to look for class_folder/init.py (because you modify the path manually.) This is a limitation of pickle so there is nothing we can do now. I would encourage you to organise your code in a way that doesn’t require to manually change the path.

I’m unsure but will check @ccordoba12 👍
