Installing fVDB

fVDB depends on PyTorch, and requires a CUDA-capable GPU. Below are the supported sofware and hardware configurations.

Software Requirements

fVDB is currently supported on the matrix of dependencies in the following table.

Operating System	PyTorch Version	Python Version	CUDA Version	Vulkan Version (only for visualization)
Linux Only	2.8.0	3.10 - 3.13	12.8	1.3.275.0

Driver and Hardware Requirements

The following table specifies the minimum NVIDIA driver versions and GPU architectures needed to run fVDB-Reality-Capture:

Operating System	Driver Version	GPU Architecture	Comptue Capability
Linux Only	550.0 or later	Ampere or later	8.0 or greater

Installation from pre-built wheels

To get started, run the appropriate pip install command for your Pytorch/CUDA versions. This command will install the correct version of fvdb-core if it is not already installed.

PyTorch 2.8.0 + CUDA 12.8

pip install fvdb-reality-capture fvdb-core==0.3.0+pt28.cu128 --extra-index-url="https://d36m13axqqhiit.cloudfront.net/simple" torch==2.8.0 --extra-index-url https://download.pytorch.org/whl/cu128

Installation from source

Note

For more complete instructions including setting up a build enviroment and obtaining the necessary dependencies, see the fVDB README.

Clone the fvdb-core repository.

git clone git@github.com:openvdb/fvdb-core.git

Next build and install the fVDB library

pushd fvdb-core
./build.sh install verbose editor_force
popd
