[QST]CMake Error at build/_deps/rapids-cmake-src/rapids-cmake/test/generate_resource_spec.cmake:82

What is your question?
~hi, gay
I got an error while building cuML, which has been bothering me for a long time

[suhansu]

I'm at cmake... He will pull a cumlprims_mg-src repository, but there seems to be some problems with this repository. When I annotate cumlprims_mg-related annotations in CMakeLists.txt, I will report a lot of problems in make where the header file is not found. I don't understand why we put cumlprims_mg-src in CMakeLists.txt.

Hi @suhansu, thanks for the issue. cumlprims-mg contains some of the multigpu code for certain algorithms. You can install it from conda rapidsai and rapidsai-nightly channels: https://anaconda.org/rapidsai-nightly/libcumlprims and https://anaconda.org/rapidsai/libcumlprims. You can also avoid the need for this dependency when building with the singlegpu option:

cuml/build.sh

Line 43 in c7f53ef

--singlegpu - Build libcuml and cuml without multigpu components

.

How are you building the repository? I would highly encourage using our conda developer environments here: https://github.com/rapidsai/cuml/blob/branch-24.10/conda/environments/all_cuda-125_arch-x86_64.yaml

Thank you for your reply, I will try it, have a good day
