Build OpenVINO™ Docker Image on CentOS 7
Authors: Xiake Sun, Su Yang
At present, OpenVINO™ officially only provides a docker image of OpenVINO™ 2021.3 for CentOS 7 on DockerHub. To deploy a docker image with the OpenVINO™ toolkit, OpenVINO™ provides the DockerHub CI named docker_ci. However, docker_ci doesn’t support CentOS 7.
Here are the steps to build the OpenVINO™ 2022.1.0 Docker Image on CentOS 7.6 with Python 3.6. In this instruction, we use Python 3.6 in the docker image as an example. If upgrading the version, the user needs to solve problems with yum and related tools.
Setup of OpenVINO™
0. Build OpenVINO™ 2022.1.0 with CMake 3.18.4 and GCC 8.3.1
Install docker on CentOS 7 and setup proxy (if any):
1. Download CMake 3.18.4
2. Install devtoolset-8 and Setup Environment
3. Build OpenVINO™ 2022.1.0 docker image with CMake 3.18.4 and GCC 8.3.1
4. Compress pre-built OpenVINO™ 2022.1.0 install package as .tgz
Setup of Docker Image
1. Build OpenVINO™ dev docker image for CentOS 7
2. Start Docker image
3. Test docker image with OpenVINO™ tools
Build OpenVINO on CentOS 7 with Script
Authors: Xiake Sun, Su Yang
We provide a script to help users easily install and test OpenVINO™ on CentOS 7.6. This script is a practice and supplement to the Building OpenVINO™ on CentOS 7 Guide in the OpenVINO™ wiki. The installation of OpenVINO™ 2022.1.0 and 2022.2.0 has been verified under the following eight configurations of CentOS 7.6 (GCC:7.3.1, 8.3.1 and Python: 3.6,3.7, 3.8, 3.9). The script could also be used for the newer version of OpenVINO with some modifications in the future.
CentOS 7 is an open-source server operating system released by the CentOS project. It was officially released on July 7, 2014. CentOS 7 is an enterprise-level Linux distribution, which is redistributed from the free and open-source code of RedHat, and its stability is trustworthy. The CentOS community and RedHat have announced that CentOS 8 will end on December 31, 2021, and CentOS 7 will end on June 30, 2024. Therefore, CentOS 7 is still the mainstream operating system of most cloud platforms.
However, CentOS 7 default GCC 4.8.5 and CMake 2.8.12 does not meet the OpenVINO software requirement for building on a Linux system. Since OpenVINO™ release 2022.1, the binary and python wheel installation packages will not be provided on CentOS 7. To help users with the verification and integration of the OpenVINO™ new version, Here we provide the installation guide and script.
1.Download OpenVINO™ and Script:
3.Script Execution Time:
The environment configuration and dependency library download time are dependent on the network environment and will not be downloaded repeatedly. Compile time depends on the hardware. Every time the script is run, the user needs clean up the previous compilation-related folders (install, build, temp) and recompile.
The script steps are similar to the Building OpenVINO™ on CentOS 7 Guide. Here are the contents with some comments. For details, please refer to the script and wiki guide.
0. Install system dependencies setup on CentOS 7.6 and install Anaconda
To test more Python version, we use Anaconda instead of Miniconda. Anaconda silent installation is recommended to avoid manually agreeing to the certificate and restarting bash (the script part is as shown below).
1. Download CMake
Download the pre-built CMake 3.18.4 and add environment variables: no need to change the existing CMake version of the system and no need to compile.
2. Install devtoolset and setup environment
Because CentOS7 was released too early, the default GCC version is 4.8.5, which does not support the compilation of OpenVINO™. Using devtoolset can install a higher version of GCC without changing the system GCC version.
The library Wheel is one of Python dependencies. Wheel 0.37.1 is recommended for OpenVINO 2022.1.0 and 2022.2.0. The higher version of Wheel is not suitable.
3. Build OV with CMake
Create a Python environment with conda and check the name of Python library and header folder.
4. Install Python Wheels
Install the two generated wheels.(runtime and development tool)
5.Model evaluation with benchmark_app and OpenVINO™ CLI usage
Install the specified version of dependencies, for ONNX 1.12 not support python3.6.
Quickly download and convert models from OpenVINO™ Toolkit - Open Model Zoo repository.
C++/Python benchmark_app: The C++ version requires additional compilation, with the Python version by default.
In the end, the script will show the OpenVINO™ usage example as below.
