OpenVINO 2019 R1: missing libmyriadPlugin.so?

[MinJia]

I'm glad the newer version of OpenVINO released, but I got the error when I'm trying to run the inference on NCS2.

The error message:

File "ie_api.pyx", line 393, in openvino.inference_engine.ie_api.IEPlugin.__cinit__
RuntimeError: Cannot find plugin to use :Tried load plugin : myriadPlugin,  error: Plugin myriadPlugin cannot be loaded: cannot load plugin: myriadPlugin from : Cannot load library 'libmyriadPlugin.so': libmyriadPlugin.so: cannot open shared object file: No such file or directory, skipping
cannot load plugin: myriadPlugin from /opt/intel/openvino_2019.1.094/python/python3.6/openvino/inference_engine: Cannot load library '/opt/intel/openvino_2019.1.094/python/python3.6/openvino/inference_engine/libmyriadPlugin.so': /opt/intel/openvino_2019.1.094/python/python3.6/openvino/inference_engine/libmyriadPlugin.so: cannot open shared object file: No such file or directory, skipping

And I check the installation process, there is no option named "Inference Engine Runtime for Intel Movidius VPU"

So, where I can find "libmyriadPlugin.so"?

Dear MinJia,

Did you carefully follow these Myriad Installation Steps ?

The Inference Engine VPU Runtime option is definitely there in your screenshot but the name of it has changed to include the wording "Vision Accelerator Design" .

Thanks,

Shubha

I have encountered the same problem. It seems that the install_GUI.sh does not install libmyriadPlugin.so in Ubuntu 18 while it does in Ubuntu 16. Maybe there is a bug in the script regarding OS version handling?

It's missing!

After installing the previous version (2018 R5.0.1), the installed plugin files look like this:

$ find /opt/intel -name *Plugin.so
/opt/intel/computer_vision_sdk_2018.5.455/deployment_tools/inference_engine/lib/centos_7.4/intel64/libGNAPlugin.so

After a full 2019 R1 installation, the file is obviously not there:

$ find /opt/intel -name *Plugin.so
/opt/intel/openvino_2019.1.094/deployment_tools/inference_engine/lib/intel64/libGNAPlugin.so
/opt/intel/openvino_2019.1.094/deployment_tools/inference_engine/lib/intel64/libMKLDNNPlugin.so

/opt/intel/openvino_2019.1.094/deployment_tools/inference_engine/lib/intel64/libHeteroPlugin.so

The same thing here for Ubuntu 18.04. The workaround is to extract package intel-openvino-ie-rt-vpu-ubuntu-bionic-2019.1.094-2019.1-094.x86_64.rpm manually.

And for Ubuntu 16.04 libmyriadPlugin.so is present.
