System information (version)

• Compiler => gcc 9.4.0
• Python => 3.8

Detailed description

Steps to reproduce

I installed OpenVINO toolkit l_openvino_toolkit_ubuntu20_2022.2 and setup variable. However when I tried to import inference_engine from openvino it yields ie_api.so: cannot open shared object file: No such file or directory although the file is there.

I also add /opt/intel/openvino/ubun20/l_openvino_toolkit_ubuntu20_2022.2.0.7713.af16ea1d79a_x86_64/python/python3.8/openvino/inference_engine to $LD_LIBRARY_PATH but without luck. Any idea how can I solve it

Is it ARM platform?

[trinhgiahuy]

Yes it does. Is it possible to install from source for Raspberry Pi 3b as I cannot see in supported device list - only Raspberry Pi 4) or should I cross compile for ARM using Docker as this issue #8343

Sorry I am newbie to this.

From the l_openvino_toolkit_ubuntu20_2022.2.0.7713.af16ea1d79a_x86_64 I see you have downloaded a package for x86_64. I suggest trying l_openvino_toolkit_debian9_arm_2022.2.0.7713.af16ea1d79a_armhf.tgz from here, because you need ARM binaries.

I suppose you have 32 bits OS?

Hello ilya-lavrenov it is 64 bits OS

You don't have to run this script for Raspbian OS. OpenVINO can work without those dependencies.
