3 years ago Hi @marcchale,
Can you please give me more details of what integer you wanted to change? Remember that if the integer is inside a library we can't modify the package unless you have the package on a development setting.

3 years ago @steff456 Greetings and thank you for reaching out. I opened an object of "multi-trace" class from a library called pymc3. https://docs.pymc.io/api/inference.html#pymc3.backends.base.MultiTrace. I was just exploring some results prior to plotting. I tried changing the value for attribute "chain" which is just a label for an array inside the object.

3 years ago To clarify, the multitrace object is the output of the library (normal use). I was not editing the library itself. Best Marc

3 years ago Please post the code you used to create that object, so we can try to reproduce your problem in our side.

3 years ago @ccordoba12 @steff456 I was able to recreate the error by running the following code (adapted from pymc3 documentation) then opening the variable trace from the variable explorer, then clicking on "chains", clicking on "1" and trying to change the value to another number. You may need to install a few libraries (sorry)

@dalthviz, please try to reproduce this one because it's related to the Object Explorer.
