TNT-Trajectory-Predition

A Python and Pytorch implementation of TNT: Target-driveN Trajectory Prediction and VectorNet: Encoding HD Maps and Agent Dynamics from Vectorized Representation.

ATTENTION: Currently, the training consumes a large memory (128G+) since an in-memory data loader is implemented. We'll provide a new dataloader that loading only training batches from disk for each step in the coming future.

Setup

Prerequisite

This implementation has been tested on Ubuntu 18.04 and has the following requirements:

python == 3.8.8
pytorch == 1.8.1
torch-geometric == 1.7.2 (The version of related libraries are listed as follows.)
- pytorch-cluster == 1.5.9
- pytorch-geometric == 1.7.2
- pytorch-scatter == 2.0.7
- pytorch-sparse == 0.6.10
- pytorch-spline-conv == 1.2.1
pandas == 1.0.0
tqdm == 4.60.0
tensorboard
(Optianl) nvidia-apex == 1.0
Argoverse-api

You can also install the dependencies using pip.

pip install -r requirements.txt

Data Preparation

Please download the Argoverse Motion Forecasting v1.1 and extract the compressed data to the "raw_datas" folder as stored in the following directory structure:

├── TNT-Trajectory-Prediction
│   ├── dataset
│   │   ├── raw_data
│   │   │   ├── train
│   │   │   │   ├── *.csv
│   │   │   ├── val
│   │   │   │   ├── *.csv
│   │   │   ├── test_obs
│   │   │   │   ├── *.csv
│   │   ├── interm_data

Then, direct to the root directory of this code implementation in terminal (/path_you_place_this_folder/TNT-Trajectory-Prediction) and run the command:

./scripts/preprocessing.sh

If you store the raw data at a different location, you can change relative path in the bash script with your path.

ATTENTION: If you aren't familiar with the bash script and path routing, just follow the directory structure.

Reminding: Change the mode of the bash file with "chmod +x scripts/preprocessing.sh" before running the script for the first time.

Usage

Training

To train the VectorNet model using NVIDIA GPU and CUDA:

python train_vectornet.py --data_root dataset/interm_data --output_dir run/tnt/ \
                          --aux_loss --batch_size 64 --with_cuda --cuda_device 0 \
                          --lr 0.0010 --warmup_epoch 30 --lr_update_freq 10 --lr_decay_rate 0.1

or run the bash script: ./scripts/train_vectornet.sh.

Reminding: Change the mode of the bash file with "chmod +x scripts/train_vectornet.sh" before running the script for the first time.

To train the TNT model using NVIDIA GPU and CUDA:

python train_tnt.py --data_root dataset/interm_data --output_dir run/tnt/ \
                    --aux_loss --batch_size 64 --with_cuda --cuda_device 0 \
                    --lr 0.0010 --warmup_epoch 30 --lr_update_freq 10 --lr_decay_rate 0.1

or run the bash script: ./scripts/train_tnt.sh.

Reminding: Change the mode of the bash file with "chmod +x scripts/train_vectornet.sh" before running the script for the first time.

For more configuretion, please refer to the parsers in train_tnt.py and train_vectornet.py.
For users with multiple GPUs, this implementation uses NVIDIA Apex library to enable the distributed parallel training. To enable the multi-gpu training:
```
python -m torch.distributed.launch --nproc_per_node=2 train_tnt.py ...
```
or enable corresponding command in the bash scripts for training.

Inference

A python script named "test_tnt.py" is provided for the inference of TNT model. It can make prediction on the test set and generate .h5 files required by the Argoverse benchmark. You need to specify the file path to your trained model file or checkpoint. Since the model are trained in the relative coordinate, a coordinate conversion has been enabled to recover the world coordinates of the predicted trajectories.

Reminding: Specify either the file path to the checkpoint or the trained model. Also, specify the path to your dataset if you are using a different directory structure.

The prediction result can be genearted withe command:

python test_tnt.py -rm Path_to_Your_Model_File

Others

TBD
