Here are some more details about this specific migrator:

The transition to CUDA 12 SDK includes new packages for all CUDA libraries and build tools. Notably, the cudatoolkit package no longer exists, and packages should depend directly on the specific CUDA libraries (libcublas, libcusolver, etc) as needed. For an in-depth overview of the changes and to report problems see this issue. Please feel free to raise any issues encountered there. Thank you! :pray:

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Seeing the following error on CI:

CMake Error at /home/conda/feedstock_root/build_artifacts/prismatic_split_1685611790359/_build_env/share/cmake-3.26/Modules/FindCUDA.cmake:861 (message):
  Specify CUDA_TOOLKIT_ROOT_DIR

Looking at the recipe, am seeing lines like this that reference $CUDA_HOME

https://github.com/conda-forge/prismatic_split-feedstock/blob/5502811254b8390279342a9077901276d91b1c40/recipe/combined_build_install.sh#L39

As of CUDA 12, the headers and libraries are now added to $PREFIX. So there is no longer a $CUDA_HOME variable. Think either only passing $CUDA_HOME when set or using something like this would do the trick:

"${CUDA_HOME:-$PREFIX}"

Edit: For more info about the CUDA 12 bringup, please see issue ( https://github.com/conda-forge/conda-forge.github.io/issues/1963 )
