Hi @martin-woschitz thank you for reporting this issue. This first message is just a warning so it shouldn’t cause any issues running your code, also the second message is an informatio output about the user account that you’ve logged in. When does the Ipython kernel stops working, is it when you’re running a python script? would it be possible to make a new virtual environment and install wandb only there to test if that’s what’s causing the issue for you?
