Usage

Dependencies

pip install --upgrade git+https://github.com/divamgupta/pytorch-propane
pip install torch==1.4.0 torchvision==0.5.0
pip install opencv-python
pip install torchgeometry

Dataset and Directories

For the example we use the following directories:

• Datasets : ./datasets/carla/ and ./datasets/kitti/
• Weights : ./sbevnet_weights/carla and ./sbevnet_weights/kitti
• Predictions : ./predictions/kitti ./predictions/carla

Download and unzip the datasets and place them in ./datasets directory

• CARLA dataset: https://huggingface.co/datasets/divamgupta/sbevnet_data/tree/main
• KITTI dataset: https://huggingface.co/datasets/divamgupta/sbevnet_data/tree/main
• Trained models: https://huggingface.co/datasets/divamgupta/sbevnet_data/tree/main
