Trying to run cuda samples on vscode windows 11 and i cant seem to get it to work,I keep getting helper_cuda.h :no such file or directory.ive tried every solution ive seen and its still not working.

It’s in the samples directory. If you have cloned the repo, the file is here. If you haven’t cloned the repo (meaning you installed a version of CUDA like 11.4 or earlier) then it will have been installed by the CUDA installer, and see below about finding the file.

So it may be a matter of the include paths you have specified in the project. First locate the file on your machine, using the hints I have given above (or use a windows tool like file manager search), then study your project include file path settings to make sure the location of that file is properly referenced in your project include path settings.
