Drake - Frame visualization attribute error

Running the example /examples/kuka_iiwa_arm/kuka_simulation gives me the following error:

Blockquote Traceback (most recent call last): File "/home/felix/.cache/bazel/_bazel_felix/6a5b9f62883c4665b1f398a636821629/external/drake_visualizer/lib/python2.7/site-packages/director/lcmUtils.py", line 117, in handleMessage callback(msg, channel=channel) File "/home/felix/git/drake/bazel-bin/tools/drake_visualizer.runfiles/drake/tools/workspace/drake_visualizer/plugin/show_frame.py", line 93, in _handle_message frame_channel.handle_message(msg) File "/home/felix/git/drake/bazel-bin/tools/drake_visualizer.runfiles/drake/tools/workspace/drake_visualizer/plugin/show_frame.py", line 36, in handle_message vis.updateFrame(transform, name, parent=folder, scale=0.1) File "/home/felix/.cache/bazel/_bazel_felix/6a5b9f62883c4665b1f398a636821629/external/drake_visualizer/lib/python2.7/site-packages/director/visualization.py", line 879, in updateFrame obj.copyFrame(frame) AttributeError: 'ContainerItem' object has no attribute 'copyFrame'

Example was started with:
bazel-bin/tools/drake_visualizer &
./bazel-bin/examples/kuka_iiwa_arm/kuka_simulation

bazel-bin/lcmtypes/drake-lcm-spy shows that the channel DRAKE_DRAW_FRAMES is up and messages are being transmitted.

Information about my system:
Operating system: Ubuntu 18.04
gcc: gcc (Ubuntu 7.4.0-9ubuntu1~18.04.york0) 7.4.0
python: Python 2.7.15+ // This is the default python version
bazel run @drake//common:print_host_settings: gcc (Ubuntu 7.4.09ubuntu1~18.04.york0) 7.4.0
cmake: 3.15.4

drake was built from source using bazel 0.29.0

If I run
bazel-bin/tools/drake_visualizer &
./bazel-bin/manipulation/util/geometry_inspector ./manipulation/models/iiwa_description/sdf/iiwa14_no_collision.sdf

The Kuka arm is shown in the visualizer and I can use the sliders to control the configuration of the arm.

Edit: My problem is that when I run /examples/kuka_iiwa_arm/kuka_simulation, no frames are displayed in the visualizer.

This should be fixed once we update the version of Director shipped with Drake. We're already in the process of doing so via our Python 3 update: https://github.com/RobotLocomotion/drake/issues/12046

Thanks for reporting this!
