Dockerfile for 3D Gaussian splatting

Dockerfile

## Unofficial Dockerfile for 3D Gaussian Splatting for Real-Time Radiance Field Rendering
## Bernhard Kerbl, Georgios Kopanas, Thomas Leimkühler, George Drettakis
## https://repo-sam.inria.fr/fungraph/3d-gaussian-splatting/

# Use the base image with PyTorch and CUDA support
FROM pytorch/pytorch:2.0.1-cuda11.7-cudnn8-devel


# NOTE:
# Building the libraries for this repository requires cuda *DURING BUILD PHASE*, therefore:
# - The default-runtime for container should be set to "nvidia" in the deamon.json file. See this: https://github.com/NVIDIA/nvidia-docker/issues/1033
# - For the above to work, the nvidia-container-runtime should be installed in your host. Tested with version 1.14.0-rc.2
# - Make sure NVIDIA's drivers are updated in the host machine. Tested with 525.125.06
