Bug: "gca() got an unexpected keyword argument 'projection'"

[BenjaminPoole]

Hi I'm using numpy version 1.23.4 and in line 10 of util/camera_pose_visualizer.py self.ax = self.fig.gca(projection='3d') does not work as numpy have changed the .gca function. I was able to fix this by replacing that line with
self.ax = self.fig.add_subplot(projection='3d')

Thanks for your trouble shooting and solution!
