CUDA
CUDA-only packages are stored in the cudaPackages
packages set. This set
includes the cudatoolkit
, portions of the toolkit in separate derivations,
cudnn
, cutensor
and nccl
.
A package set is available for each CUDA version, so for example
cudaPackages_11_6
. Within each set is a matching version of the above listed
packages. Additionally, other versions of the packages that are packaged and
compatible are available as well. For example, there can be a
cudaPackages.cudnn_8_3_2
package.
To use one or more CUDA packages in an expression, give the expression a cudaPackages
parameter, and in case CUDA is optional
cudaSupport ? false
cudaPackages ? {}
When using callPackage
, you can choose to pass in a different variant, e.g.
when a different version of the toolkit suffices
mypkg = callPackage { cudaPackages = cudaPackages_11_5; }
If another version of say cudnn
or cutensor
is needed, you can override the
package set to make it the default. This guarantees you get a consistent package
set.
mypkg = let
cudaPackages = cudaPackages_11_5.overrideScope' (final: prev {
cudnn = prev.cudnn_8_3_2;
}});
in callPackage { inherit cudaPackages; };
