'ObjectDetection' object has no attribute 'cfg_tb'

Hi All,

I'm trying to run PointPillars with KITTI, and I keep getting the error 'ObjectDetection' object has no attribute 'cfg_tb'. Can anyone see a fix for this? I'll admit I'm new to Linux and not the most established programmer, but I'm imagining that cfg_tb is something to do with tensorboard having looked at the ObjectDetection code?

Also to note, with no changes the network ran for one epoch, but that was isolated and it gave this error again after the epoch was finished. Many thanks in advance!

Environment:

Ubuntu 20.04 Guest inside VirtualBox on a Windows 10 Pro Host Open3D 0.13.0 Tensorflow 2.4.1

Code:

import open3d.ml as _ml3d
import open3d.ml.tf as ml3d
from path import Path

cfg_file = Path('/media/sf_PhD_Work/PP_config.yml')
cfg = _ml3d.utils.Config.load_from_file(cfg_file)

dataset = ml3d.datasets.KITTI(cfg.dataset.pop('dataset_path', None), **cfg.dataset)

model = ml3d.models.PointPillars(**cfg.model)

pipeline = ml3d.pipelines.ObjectDetection(model=model, dataset=dataset,
                      device='gpu', **cfg.pipeline)

pipeline.run_train()

Returns:
