[CLDNN ERROR]. clGetPlatformIDs error -1001 - When using Integrated GPU

[K__Dhruv]

I'm running the benchmark app file as

python3 benchmark_app.py -m ~/model.xml -d gpu

This is the stack trace I get -

My system doesn't have a dedicated GPU, I'm trying to use the Integrated GPU - Intel® HD Graphics 520 (Skylake GT2).

Before this, I already ran sudo apt-get install ocl-icd-opencl-dev to install opencl

Hi Dhruv,

Thanks for reaching out, did you follow the additional Steps for Intel® Processor Graphics (GPU) and source the environment variables?

source /opt/intel/openvino/bin/setupvars.sh

If you continue to see the error, could you try to run the benchmark_app demo script as follows?

cd /opt/intel/openvino/deployment_tools/demo
./demo_benchmark_app.sh -d GPU

Regards,

Jesus
