MIVisionX Python Inference Application

MIVisionX Inference Application using pre-trained ONNX/NNEF/Caffe models.

Pre-trained models in ONNX, NNEF, & Caffe formats are supported by MIVisionX. The app first converts the pre-trained models to AMD Neural Net Intermediate Representation (NNIR), once the model has been translated into AMD NNIR (AMD's internal open format), the Optimizer goes through the NNIR and applies various optimizations which would allow the model to be deployed on to target hardware most efficiently. Finally, AMD NNIR is converted into OpenVX C code, which is compiled and wrapped with a python API to run on any targeted hardware.

Prerequisites

• Ubuntu 16.04/18.04 or CentOS 7.5/7.6
• ROCm supported hardware
  • AMD Radeon GPU or AMD APU required
• Latest ROCm
• Build & Install MIVisionX
