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.
Downloads¶
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.
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.
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
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.hmust have#undef NO_ERRORas theNO_ERRORdefined inwinerror.hconflicts withTrueface::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.
