[ ERROR ] Cannot find plugin to use :Tried load plugin : MKLDNNPlugin UBUNTU

[Melnychuk__Mykhailo]

I tried to launch command

sudo ./classification_sample -i '/home/mykh/June_odd-eyed-cat_cropped.jpg' -m '/opt/intel/computer_vision_sdk/deployment_tools/model_optimizer/install_prerequisites/inception_v1_inference_graph.xml'

and got
 

[ ERROR ] Cannot find plugin to use :Tried load plugin : MKLDNNPlugin,  error: Plugin MKLDNNPlugin cannot be loaded: cannot load plugin: MKLDNNPlugin from : Cannot load library 'libMKLDNNPlugin.so': libmkl_tiny_omp.so: cannot open shared object file: No such file or directory, skipping

also I called
source <INSTALL_DIR>/bin/setupvars.sh .

but it's doesn't help/

Hi Mykhailo,

I'm not sure that you need sudo permissions (and environment!) to get this working.

Actually if you need to get this working under sudo try to pass user environment to it (e.g. by sudo -E ...) supposing that you already executed

"source /opt/intel/computer_vision_sdk/bin/setupvars.sh" under user.

Dear Mykhailo if you successfully ran "source /opt/intel/computer_vision_sdk/bin/setupvars.sh"  and from the same shell ran the classification_sample, you should not have problems. You definitely do not need to be sudo to run OpenVino samples.

Hope it helps,

Thanks for using OpenVino !

even after intializing the enviornment wihtin the same terminal, the results is the same.
