530 Views

You can show the steps to execute k-means in the onedal sample code, and how to build the project.

 

I had a lot of problems executing the sample code.

 

Don't know how to build projects.

You could look at the oneDAL Getting Started Guide follow the link:

https://www.intel.com/content/www/us/en/docs/onedal/get-started-guide/2024-0/overview.html


please check there how to Build and run the examples from oneDAL as an example


# Navigate to the directory containing examples and then build them:

cd /examples/oneapi/dpc

make so example=svm_two_class_thunder_dense_batch # This will compile and run Correlation example using Intel(R) oneAPI DPC++/C++ Compiler

make so mode=build # This compiles all examples in the current directory
