I am getting Failed to initialize Inference Engine backend (device = GPU) error

Hi,

This is the error I am receiving: 

> Failed to initialize Inference Engine backend (device = GPU): Failed to create plugin /opt/intel/openvino_2021.4.752/deployment_tools/inference_engine/lib/intel64/libclDNNPlugin.so for device GPU
> Please, check your environment
> [CLDNN ERROR]. clGetPlatformIDs error -1001

 

Hardware:

  • I7-11700K,
  • MSI Tomahawk Z690 Motherboard,
  • 32GB 3200Mhz Cl14 Ram,
  • 1TB Nvme SSD,
  • and 750 watt PSU.
  • No dedicated GPU, using the iGPU.

Environment:

  • OS: Ubuntu 20.04 LTS
  • Running a Python 3.7 Environment in Conda and I am trying to inference an Efficientnet model I optimized through OpenVino with OpenCV on GPU.
  • I used FP16 during optimization.

Code:

import cv2
model = cv2.dnn.readNet(model_path)
model.setPreferableBackend(cv2.dnn.DNN_BACKEND_INFERENCE_ENGINE)
model.setPreferableTarget(cv2.dnn.DNN_TARGET_OPENCL_FP16 )
 
Attempted Fixes:
  • Reinstalled OpenVino
  • Reinstalled the OS/Environment

Further Notes:

  • I followed the directions and everything works fine on my I7 TigerLake NUC.
  • Additionally this runs fine when I try to inference on CPU as well.
Any insights on how I should fix this?
Thanks.

Hi hlreicha,


Thanks for reaching out to us.


Please try to install the GPU driver version 21.29.20389 and see whether it can work. You can rerun the script in /opt/intel/openvino_2021/install_dependencies/ directory with the command below:

sudo -E ./install_NEO_OCL_driver.sh --install_driver 21.29.20389

 

If you still getting the error: [CLDNN ERROR]. clGetPlatformIDs error -1001, try to check and troubleshoot by referring to Driver issues troubleshooting.



Regards,

Peh
