openvino detecting igpu only when connected to the montior.

[sumbin]

Hi ,

I am using Up 7000 board with intel n50 processor https://up-board.org/up-7000/

I have installed ubuntu 22.04 lts .

I have followed these instructiions to install openvino 2023.3

https://docs.openvino.ai/2023.3/openvino_docs_install_guides_installing_openvino_from_archive_linux.html 

I have followed these instruction to configure gpu for openvino https://docs.openvino.ai/2023.3/openvino_docs_install_guides_configurations_for_intel_gpu.html

Openvino can detect gpu only when I connect the board to a monitor using hdmi and login otherwise no gpu is detected.

Once detected the inference is fine.

Please guide me to fix this

Hi Sumbin,

Thanks for reaching out to us.

Could you please install the recommended driver for Intel® iGPU via the following option and see if the issue can be resolved?

• Via system package manager
• Via Manual download

Regards,

Wan

Hi Wan,

Thanks for the reply.

I have installed the recommended driver using both the options.

Only when I install the driver, Openvino can detect gpu when I connect the board to a monitor and login.

If I dont install the recommended driver openvino doesent detect gpu at all

Hi Sumbin,

Thanks for the information.

Are you running an inference with the GPU plugin when connecting remotely to the UP 7000 board with remote client software? Could you please share the error code that you encountered when inferencing with the GPU plugin without a monitor?

On the other hand, could you please try the following workaround and see if the issue can be resolved?

• Enable Display Emulation in BIOS.
• If you are using remote client software, use a different remote access software, such as Microsoft Remote Desktop Connection or 2X RDP Client. 

Regards,

Wan

• No I am not using any remote client software.I am doing ssh to UP 7000 from a ubuntu terminal on a pc.

• when DEVICE=''GPU" error is

  exec_net = ie.load_network(network=net, device_name=DEVICE)
  File "ie_api.pyx", line 427, in openvino.inference_engine.ie_api.IECore.load_network
  File "ie_api.pyx", line 471, in openvino.inference_engine.ie_api.IECore.load_network
  RuntimeError: [ GENERAL_ERROR ] Check 'all_devices.size() > idx' failed at src/plugins/proxy/src/plugin.cpp:523:
  Cannot get fallback device for index: 0. The total number of found devices is 0

On the other hand, could you please try the following workaround and see if the issue can be resolved?

• Enable Display Emulation in BIOS. - Not finding this option is BIOS.
  
• If you are using remote client software, use a different remote access software, such as Microsoft Remote Desktop Connection or 2X RDP Client. - I have not used any remote access software
  

 I also ran python program to check the available devices using openvino from crontab.

 Still no gpu detected by openvino

Hi Sumbin,

Thanks for your patience.

For your information, I've SSH into a Ubuntu machine with Intel® Core™ i5-11400 Processor and checked the GPU plugin when the monitor is not connected to the machine. The GPU plugin was able to detect successfully.

Could you please try the steps as follows and see if the GPU plugin can be detected?

1. Set up Python Virtual Environment
   python3 -m venv openvino_env
   
   
2. Activate Virtual Environment
   source openvino_env/bin/activate
   
   
3. Set up and update PIP to the highest version
   python -m pip install --upgrade pip
   
   
4. Install the OpenVINO™ Development Tools package
   pip install openvino-dev
   
   
5. Paste the following command in Terminal
   python
   from openvino.runtime import Core
   ie = Core()
   ie.available_devices​

Wan

hi Wan,

Any update from your side

Hi Sumbin,

Thanks for your patience. We've received feedback from relevant team.

OpenVINO™ toolkit detects GPU using OpenCL™ API. Please try to run clinfo command in both monitor and monitorless config. Please check board features (power or advanced) whether iGPU is switched off in case of monitor is unplugged.

Wan
