OpenVINO 2019.1.114 on Ubuntu 18.04

[McDonald__John]

Hi,

Is OpenVino 2019.1.114 compatible with Ubuntu 18.04?

I have just installed OpenVino 2019.1.114 on Ubuntu 18.04 but am having problems running some of the sample applications. The two demos (i.e.demo_security_barrier_camera.sh  and demo_squeezenet_download_convert_run.sh) run ok, but when I try to run anything else I keep getting the following error:

[ ERROR ] Cannot make shared blob! The blob type cannot be used to store objects of current precision

This is from models downloaded using the downloader.py. For example I have tried running the pedestrian tracker demo using the person detection and retail models as explained here: https://docs.openvinotoolkit.org/latest/_inference_engine_samples_pedestrian_tracker_demo_README.html

with the following output:
 

$ ./pedestrian_tracker_demo -i ~/Downloads/P1033658.mp4 -m_det /opt/intel/openvino_2019.1.144/deployment_tools/tools/model_downloader/Retail/object_detection/pedestrian/rmnet_ssd/0013/dldt/person-detection-retail-0013.xml -d_det CPU  -m_reid /opt/intel/openvino_2019.1.144/deployment_tools/tools/model_downloader/Retail/object_reidentification/pedestrian/rmnet_based/0031/dldt/person-reidentification-retail-0031.xml -d_reid CPU

Has anyone experienced similar problems ... and more importantly got any suggested solutions?

Thanks,

Dear McDonald, John,

Ubuntu 18 is technically not supported by OpenVino. However, many in the community have made it work.

Thanks,
