HDDL Plugin with Ubuntu 20.04 LTS

Hello,

I attempt to run OpenVINO demos with HDDL plugin using OpenVINO 2021.1 and Ubuntu 20.04, but get the following error:

Cannot load library '/opt/intel/openvino_2021/deployment_tools/inference_engine/lib/intel64/libHDDLPlugin.so': libjson-c.so.3: cannot open shared object file: No such file or directory


libjson-c.so.3 was included in Ubuntu 18.04 LTS, but was replaced by libjson-c.so.4 in Ubuntu 20.04 LTS. Also, I had to install IEI Reset software for Ubuntu 18.04, as there is no version available for Ubuntu 20.04.

Based on the above, I conclude that HDDL plugin does not currently support Ubuntu 20.04 LTS. Is that correct? And if yes, could you let me know when Ubuntu 20.04 will be supported or what else I could possible do to run HDDL plugin in Ubuntu 20.04.

Thank you!

Hi Catriona,

Greetings to you.

The officially supported OS for Intel® Vision Accelerator Design with Intel® Movidius™ Vision Processing Units (VPU) is Ubuntu 18.04 long-term support (LTS), 64-bit (Linux Kernel 5.2 and below).


For future support, we do not have any information regarding the timeline, but we can tell you that developers are working on enabling support for more OpenVINO components in Ubuntu 20.04 LTS.


Regards,

Munesh

Hi Catriona,

I’ve tested HDDL Plugin using Image Classification verification script for Intel® Movidius™ VPUs in Ubuntu 20.04 LTS, and it works fine.

Please install dependencies for HDDL plugin following the configuration guide given below

https://docs.openvinotoolkit.org/2021.2/openvino_docs_install_guides_installing_openvino_linux_ivad_...

 

and verify using Image Classification verification script.

https://docs.openvinotoolkit.org/2021.2/openvino_docs_get_started_get_started_linux.html#image_class...

 

Please note that while the HDDL plugin works with Ubuntu 20.04 LTS, the officially supported OS is Ubuntu 18.04 LTS.

 

Regards,

Munesh
