DeprecationWarning when creating a visual.Rect object

I’m having this error when I’m creating a visual.Rect object:

Traceback (most recent call last):
  File "fb_02_threads_labels.py", line 526, in <module>

DeprecationWarning: elementwise comparison failed; this will raise an error in the future.

Any ideas of why is this happening?

This is an odd error - that line should be perfectly valid Python regardless of the value of vertices. I notice you’re using an anaconda environment, so it could be something specific to conda… What version of Python are you using?
