You can access configuration values as object attributes (cfg.{property_name})
or dictionary key values (cfg['{property_name}']
)

Standard convention for object detection lidar datasets (e.g. KITTI / Waymo) is x(red) = forward, y (green) = left, z (blue) = up. Add XYZ labels to the axis.
Mention that datasets may instead of r (lidar reflectance) as feature, or no features at all.
A dataset is partitioned into train(ing), valid(ation) and test(ing) splits. Models use data from the training split to update network weights and performance is measured on the validation split. Hyperparameters can be adjusted to optimize performance on the validation split. The test split is never used during the training step and is only used to report the final performance.

Both PyTorch and TF can be installed. User code just needs to choose one inside a specific python file.
requirements-torch.txt
if Nvidia GPU is not available.

Also talk about:
Continuing training from a checkpoint.
Point to the tensorboard tutorial for visualizing training progress.

Re-write condensed tutorials based on suggestions.
Changes were made to 3 tutorial notebooks
Suggested changes were:
docs/tutorial/notebook/
for all data, model checkpoint logs etc. (all notebooks)01_config_files.ipynb
)01_config_files.ipynb
)02_datasets.ipynb
)02_datasets.ipynb
)Please note:
02_datasets.ipynb
will not run because the notebook does not have access to smaller version of semanticKITTI dataset.@sanskar107 can you share a downloadable link for that dataset that I canWill use shared link https://cdn.discordapp.com/attachments/903644960211992607/946792875423838288/semkitti.zip.wget
in the the notebook?Inference_on_a_custom_data.ipynb
,reading_a_config_file.ipynb
,reading_a_dataset.ipynb
,train_ss_model_using_pytorch.ipynb
andtrain_ss_model_using_tensorflow.ipynb
before merging because they are essentially duplicates. Keeping them here for reference temporarily.This change is![Reviewable](https://camo.githubusercontent.com/1541c4039185914e83657d3683ec25920c672c6c5c7ab4240ee7bff601adec0b/68747470733a2f2f72657669657761626c652e696f2f7265766965775f627574746f6e2e737667)
