Project description

nvdocker is library built on top of the docker-py python sdk to build and run docker containers using nvidia-docker.

Targets nvidia-docker2

Installation

pip install nvdocker

Usage

These variables are already set in NVIDIA’s official CUDA images.

visible_devices

This variable controls which GPUs will be made accessible inside the container.

  • Possible values:
    • 0,1,2, GPU-fef8089b …: a comma-separated list of GPU UUID(s) or index(es),
    • all: all GPUs will be accessible, this is the default value in our container images,
    • none: no GPU will be accessible, but driver capabilities will be enabled.
    • void or empty or unset: nvidia-container-runtime will have the same behavior as runc.

driver_capabilites

This option controls which driver libraries/binaries will be mounted inside the container.

  • Possible values
    • compute,video,graphics,utility …: a comma-separated list of driver features the container needs,
    • all: enable all available driver capabilities.
    • empty or unset: use default driver capability: utility.
  • Supported driver capabilities
    • compute: required for CUDA and OpenCL applications,
    • compat32: required for running 32-bit applications,
    • graphics: required for running OpenGL and Vulkan applications,
    • utility: required for using nvidia-smi and NVML,
    • video: required for using the Video Codec SDK.

require

A logical expression to define constraints on the configurations supported by the container.

  • Supported constraints
    • cuda: constraint on the CUDA driver version,
    • driver: constraint on the driver version,
    • arch: constraint on the compute architectures of the selected GPUs.

Expressions

Multiple constraints can be expressed in a single environment variable: space-separated constraints are ORed, comma-separated constraints are ANDed.
Multiple environment variables of the form rew are ANDed together.

cuda

The version of the CUDA toolkit used by the container. If the version of the NVIDIA driver is insufficient to run this version of CUDA, the container will not be started.

Possible values
  • cuda>=7.5, cuda>=8.0, cuda>=9.0 …: any valid CUDA version in the form major.minor.

cuda_vesion

Similar to NVIDIA_REQUIRE_CUDA, for legacy CUDA images.
In addition, if NVIDIA_REQUIRE_CUDA is not set, NVIDIA_VISIBLE_DEVICES and NVIDIA_DRIVER_CAPABILITIES will default to all.

disable_require

Single switch to disable all the constraints of the form
