If you're attempting to utilize your Nvidia GPU with Docker containers, you might encounter the frustrating "could not select device driver" error. This error can stem from various underlying issues, but luckily, this comprehensive guide provides a step-by-step solution to address almost every cause of this problem.
The Common Culprits and Their Fixes
The Removal Ritual: Begin by purging any existing Nvidia and Cuda drivers with the following commands:sudo apt-get remove -y --purge '^nvidia-.*' sudo apt-get remove -y --purge '^libnvidia-.*' sudo apt-get remove -y --purge '^cuda-.*'
Reinstallation and Reboot: After purging the old drivers, follow the official Nvidia Cuda installation guide meticulously. A system reboot after installation is crucial for ensuring everything settles in correctly.
The Kernel Check: Confirm the correct kernel headers are installed:sudo apt install linux-headers-$(uname -r)
DKMS for Dynamic Kernel Modules: The DKMS (Dynamic Kernel Module Support) package enables your Nvidia drivers to automatically adapt to kernel updates. Install DKMS:sudo apt install dkms
DKMS Verification and Installation: Ensure the Nvidia driver is recognized by DKMS:dkms status nvidia
If the driver isn't yet installed, execute this command: sudo dkms install -m nvidia -v
The Reboot Ritual: A reboot after these modifications is essential to allow the changes to take effect.
Installation and Configuration: Install Nvidia-docker2 and restart Docker:sudo apt install --reinstall -y nvidia-docker2 sudo systemctl daemon-reload sudo systemctl restart docker
The Nvidia-smi Test: Try running nvidia-smi. If it successfully outputs your GPU information, you're on the right track!Docker Container Check: Launch a Docker container requiring GPU resources. If it runs without the "could not select device driver" error, you've triumphed over this frustrating obstacle!
Additional Tips for Success
Updating your system: Make sure your operating system is up-to-date with the latest updates, including kernel updates. This ensures compatibility and helps address potential bugs.Nvidia Driver Compatibility: Check for the latest Nvidia drivers compatible with your system and GPU model. Outdated or incompatible drivers can be a source of issues.Docker Version: Ensure you're using a recent version of Docker. Older versions might lack full support for GPU features.
The Power of the Debugger: A Final Resort
Enabling Debug Logging: Set the Docker logging level to debug:sudo systemctl edit --full docker
Then, add the following lines within the [Service] section: Environment="DOCKER_LOG_LEVEL=debug"
Analyzing the Logs: After restarting Docker, examine the Docker logs for clues related to the error. You might find specific errors or warnings pointing towards the underlying problem.
