A flexible Python front-end inference SDK.
-
Flexible
FlexInfer has a Python front-end, which makes it easy to build a computer vision product prototype.
-
Efficient
Most of time consuming part of FlexInfer is powered by C++ or CUDA, so FlexInfer is also efficient. If you are really hungry for efficiency and don't mind the trouble of C++, you can refer to CheetahInfer.

- Linux
- Python 3.6 or higher
- TensorRT 7.1.3.4 or higher
- PyTorch 1.4.0 or higher
- CUDA 10.2 or higher
- volksdep 3.2.0 or higher
We have tested the following versions of OS and softwares:
- OS: Ubuntu 16.04.6 LTS
- Python 3.6.9
- TensorRT 7.1.3.4
- PyTorch 1.6.0
- CUDA: 10.2
- volksdep: 3.2.0
- If your platform is x86 or x64, you can create a conda virtual environment and activate it.
conda create -n flexinfer python=3.6.9 -y
conda activate flexinfer-
Install volksdep following the official instructions
-
Setup
pip install "git+https://github.com/Media-Smart/flexinfer.git"We provide some examples for different tasks.
