Forbid `renderer.RemoveActor` printing info

Hi,

I use VTK in python now and it works fine.
But when I remove actor renderer.RemoveActor(my_actor) I can see a lot of output messages like this:

How to prevent VTK from printing these messages when removing actors?

Hello,

Those messagens are usually generated by a call to the actor’s Print() method. Python is known to make implicit calls all the time. While this makes life easier, it is a source of bugs. Maybe in your code there is a forgotten print(actor) used during debugging or even just an actor loose in a line of code.

best,

PC

Sorry for the late reply,

Yes, I used to have a print(actor) explicitely.
I’m so ashamed. Sorry for disturbing the community with such a silly question :frowning:

Thank you for the help!

No worries. Leaving behind debug messages can happen to any developer.
