Debugging DaVinciResolve in Docker: NVidia GPUs Not Detected

Debugging DaVinci Resolve Docker: NVIDIA GPUs Not Detected

In this article, we will discuss the common issues and solutions for debugging DaVinci Resolve Docker when NVIDIA GPUs are not detected. We will cover key concepts, provide detailed context, and include subtitles and code blocks where necessary.

Introduction

DaVinci Resolve is a popular video editing software used by many professionals and enthusiasts. Running DaVinci Resolve in a Docker container can provide several benefits, such as portability, consistency, and easier management. However, one common issue that users face is that NVIDIA GPUs are not detected when running DaVinci Resolve in a Docker container.

Debugging DaVinci Resolve Docker: NVIDIA GPUs Not Detected

When running DaVinci Resolve in a Docker container, you might encounter the following error:

Running nvidia-smi doe...
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

This error indicates that the NVIDIA runtime is not properly configured or that the NVIDIA driver is not installed or running. To debug this issue, you can follow the steps below:

Step 1: Install NVIDIA Runtime

First, you need to make sure that the NVIDIA runtime is installed on your system. You can install the NVIDIA runtime by running the following command:

sudo apt-get install nvidia-container-toolkit

Step 2: Configure Docker to Use NVIDIA Runtime

After installing the NVIDIA runtime, you need to configure Docker to use the NVIDIA runtime. You can do this by adding the following line to your Docker daemon configuration file:

{
"runtimes": {
"nvidia": {
"path": "nvidia-container-runtime",
"runtimeArgs": []
}
}
}

After adding this line, you need to restart the Docker daemon for the changes to take effect.

Step 3: Run DaVinci Resolve Docker with NVIDIA Runtime

After configuring Docker to use the NVIDIA runtime, you can run DaVinci Resolve Docker with the following command:

docker run --runtime=nvidia --gpus all -it --rm -p 8080:8080 -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY davinciresolve/resolve:latest

This command will run DaVinci Resolve Docker with the NVIDIA runtime and use all available GPUs. Make sure to replace "/tmp/.X11-unix:/tmp/.X11-unix" with the correct path for your system.

Step 4: Verify NVIDIA GPU Detection

After running DaVinci Resolve Docker with the NVIDIA runtime, you can verify that the NVIDIA GPU is detected by running the following command:

docker exec -it  nvidia-smi

This command will display the NVIDIA System Management Interface (nvidia-smi) output, which will show the detected NVIDIA GPU(s).

Debugging DaVinci Resolve Docker when NVIDIA GPUs are not detected can be a challenging task. However, by following the steps outlined in this article, you can ensure that the NVIDIA runtime is properly configured and that the NVIDIA GPU is detected by DaVinci Resolve Docker. By doing so, you can take advantage of the benefits of running DaVinci Resolve in a Docker container while ensuring that the NVIDIA GPU is properly utilized.
