Trueface SDK Reference - Stable

Welcome to the Trueface SDK. The SDK allows you to integrate Trueface’s AI models directly into your application while ensuring maximum performance and flexibility. Start by downloading the correct version of the SDK for your target platform and desired language. Next, refer to the General section for guidance on how to initialize the SDK.

Stable release version 0.21.8922

Choosing Your Release Type

Alpha contains the absolute latest features (updated daily), but may also contain bugs. Beta contains fewer bugs while still having relatively new features. Stable will contain the fewest bugs but will take the longest to get new features. You will generally want to choose the Beta or Stable releases.

Note, if downloading the SDK in an automated manner (ex. building docker images) and you always require the latest SDK version, then replace the postfix in the download link (SDK version) with _latest.zip instead. So for example, https://reference.trueface.ai/cpp/staging/latest/uploads/truefaceSDK_v0.10.5483.zip would become https://reference.trueface.ai/cpp/staging/latest/uploads/truefaceSDK_latest.zip.

If you require a previous version of the documentation or SDK downloads, refer to the Previous Stable Releases tab on the left.

GPU SDK Dependencies

While the CPU SDK is dependency free (only requires OpenMP for Linux and Windows), the GPU SDK does have a few dependencies which must be installed. As of right now, the CUDA 10.1 SDK supports Ubuntu and CentOS, while the CUDA 11.2 SDK only supports Ubuntu (this is due to GLIBC versions). We will assume you already have the nvidia drivers installed on your machine.

CUDA 10.1 - Ubuntu
You will need to install CUDA 10.1, cudnn7, libomp, libgomp, and libopenblas.
All the necessary runtime dependencies can be installed on Ubuntu 18.04 by running the following commands:
apt-get install -y libomp-dev libopenblas-dev software-properties-common libgomp1
add-apt-repository ppa:graphics-drivers
apt-key adv --fetch-keys  http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub
bash -c 'echo "deb http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 /" > /etc/apt/sources.list.d/cuda.list'
bash -c 'echo "deb http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64 /" > /etc/apt/sources.list.d/cuda_learn.list'
apt update
apt install cuda-10-1
apt install libcudnn7
export PATH=/usr/local/cuda-10.1/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

If using docker, we advise using the nvidia/cuda:10.1-cudnn7-runtime-ubuntu18.04 docker image.

If using Ubuntu 20.04 (for python bindings library), then you may have to run sudo ln -s /usr/lib/x86_64-linux-gnu/libomp.so.5 /usr/lib/x86_64-linux-gnu/libomp.so.

CUDA 10.1 - CentOS
Starting from the nvidia/cuda:10.1-cudnn7-runtime-centos8 docker image, run the following commands:
dnf --enablerepo=powertools install -y openblas-devel
dnf install -y libgomp libomp
CUDA 11.2 - Ubuntu 20.04
Starting from the nvidia/cuda:11.2.0-cudnn8-runtime-ubuntu20.04 docker image, run the following commands:
apt-get install -y libomp-dev libopenblas-dev libgomp1
ln -s /usr/lib/x86_64-linux-gnu/libomp.so.5 /usr/lib/x86_64-linux-gnu/libomp.so

Windows SDK

Our team does the majority of development and testing in a Linux environment. The Windows SDK may therefore contain more bugs than the other platform releases and may be lacking in a few features. The current known issues and limitations are as follows:

  • PostgreSQL database management system is currently not supported.

  • Any file including winerror.h must have #undef NO_ERROR as the NO_ERROR defined in winerror.h conflicts with Trueface::ErrorCodes::NO_ERROR.

As of this time, we are only supporting a release configured version of the library (and not a debug version). Additionally, the library has been built with /MT so be sure to set the flag appropriately.

Getting Started Tutorials

Every SDK download package comes bundled with sample code demonstrating proper usage of the SDK for various tasks such as face detection, face recognition, object detection, mask detection, and more. Start by understanding how the sample code works by reading the comments in the code.

Sample Apps

Sample Apps demonstrate full working applications. These extend the scope of the sample code which comes shipped with the SDK.

Reporting SDK Bugs and Documentation Errors

If you encounter a bug in the SDK, please send an email to support@trueface.ai. Please include at minimum the following:

  • SDK version

  • SDK target (ex. Python 3.7 64Bit CPU Linux)

  • Expected behaviour

  • Observed behaviour

  • A minimal reproducible code example showing how to replicate the bug

  • Any input images used

The more information you provide, the faster we can diagnose the issue and push out a fix.

If you happen to find a mistake (spelling, syntax error, etc.) in the latest Alpha, Beta, or Stable documentation, please email support@trueface.ai with a screenshot of the mistake, documentation version number (same as SDK version), and the release type (Alpha, Beta, or Stable). We will push out a fix as soon as we can.
