openvino python inference api import error

Question

I want to use openvino for object detection.
I installed it in conda environment on ubuntu 20.

I added this line in .bashrc:

export LD_LIBRARY_PATH=/home/user/anaconda3/envs/openvino/bin/python3/../../lib:${LD_LIBRARY_PATH}

I run after:

source .bashrc

which python  # gives /home/user/anaconda3/envs/openvino/bin/python
echo $PYTHONPATH # does not return anything

I try to import:

from openvino.inference_engine import IENetwork, IECore

I go this error:

from .ie_api import *
ImportError: libtbb.so.2: cannot open shared object file: No such file or directory

Answer 1

Make sure you had carefully followed these installation step. You should be able to run the examples if you had set the OpenVINO toolkit and its pre-requisite correctly.

Afterward, you can try to proceed with your attempt. Please take note that currently only these Operating Systems are supported:

Ubuntu 18.04.x long-term support (LTS), 64-bit

CentOS 7.6, 64-bit (for target only)

Yocto Project v3.0, 64-bit (for target only and requires modifications)
