Relationship between tensorboard and Open3D?

It’s so unbelievably crazy that when I built tensorboard from source, it requested from open3d.visualization import webrtc_server, which seems to me have NOTHING to do with tensorboard

Can anybody help to explain why is it so ? What a Open3D !!!

➜  tensorboard git:(master) ./bazel-bin/tensorboard/tensorboard --logdir path/to/logs

To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.

It seems Open3D might be a plugin for TensorBoard as seen here, but I think the TF discussion board or the TensorBoard GitHub repository might be a better place for the question as it seems to be unrelated to PyTorch.
