Cannot install Openvino with pip

Question

I'm trying to install Openvino to convert a Keras model into a representation for the inference engine. I'm running the command:

python3 openvino/tools/mo/mo_tf.py —model_13.h5/ --input_shape=\[180,180\]

This returns the error:

from openvino.tools.mo.subprocess_main import subprocess_main
ModuleNotFoundError: No module named 'openvino'

I've tried pip install openvino but consistently get:

ERROR: Could not find a version that satisfies the requirement openvino (from versions: none)
ERROR: No matching distribution found for openvino

To try and make sure the versions of python for running the script and installing Openvino are the same, I've tried:

python3 -m pip install openvino

The content of the mo_tf.py script is simply:

#!/usr/bin/env python3

# Copyright (C) 2018-2021 Intel Corporation
# SPDX-License-Identifier: Apache-2.0


if __name__ == "__main__":
    from openvino.tools.mo.subprocess_main import subprocess_main
    subprocess_main(framework='tf')

Has anyone seen this issue and found a workaround?

Is the python3 you're using to run the script the exact same one that you used to pip install openvino? – Scream

Yes, I've tried specifying with python3 -m pip install openvino – Bujumbura

When you try pip install openvino, does it actually say successfully installed or requirement already satisfied? – Roomette

Answer 1

The latest version of openvino is 2021.4.2. The list of packages to download by pip includes packages for Python 3.6-3.9 for Linux, MacOS on Intel, and Windows; only packages for 64-bit platforms are provided. No packages for Python 3.10 and no source code.

The solution is either to compile from sources, or install with Docker or install from Anaconda. Or downgrade to Python 3.9.

Yes, compatibility issues gives error like this, no module found, as some packages depends on specific version of python. – Geller

Supported Python version for OpenVINO on Linux, MacOS, and Windows 10 is Python 3.6-3.8. You may build the OpenVINO master branch from source. Steps to build OpenVINO from source on Linux is available at the following link: github.com/openvinotoolkit/openvino/wiki/BuildingForLinux – Westfalen

After that you can convert your .H5 model to IR according to the steps in the following page: docs.openvino.ai/2021.4/… – Westfalen

Answer 2

On a separate note, if you happen to install openvino-dev instead of openvino consider adding quote escape as by default zsh (not bash) interprets square brackets as an expression for pattern matching.

To resolve this issue, you need to escape the command with quotes:

Use this

pip install 'openvino-dev[tensorflow2,mxnet,caffe]'

Instead of

pip install openvino-dev[tensorflow2,mxnet,caffe]
