Hi @blancfrederic thank you for the report! I think this can happen if you try to load variables while your current setup has a different version of the packages used to create such variables 🤔

Some similar issues: https://github.com/spyder-ide/spyder/issues?q=is%3Aissue+TypeError%3A+a+number+is+required+is%3Aclosed

Also, maybe this kind of error should be catch and some sort of error dialog should be shown explaining what is happening when an error like this occurs @ccordoba12 ?

Thanks for your answer ... yes you're right. I succeed in loading the file in another conda env ...

That's a good idea. Perhaps we should catch any error when trying to load a spydata file and tell users what are the possible causes for it: missing packages in the Spyder env, different Python versions or incompatible package versions (e.g. Numpy 1 vs. 2). I can't think of any other possible cause.
