MIVisionX Python ML Model Validation Tool#

MIVisionX ML Model Validation Tool using pre-trained ONNX / NNEF / Caffe models to analyze, summarize, & validate.

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.

Analyzer Index#

Prerequisites#

	pip install pyqtgraph

  • Export Path & Libraries required

	export PATH=$PATH:/opt/rocm/bin
	export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/rocm/lib

NOTE: To get the best performance from the validation toolkit use the RPP Develop Branch

  • Install OpenMP

sudo apt-get install libomp-dev

export OMP_NUM_THREADS=<number of threads to use>

Use MIVisionX Docker#

MIVisionX provides developers with docker images for Ubuntu 16.04, Ubuntu 18.04, CentOS 7.5, & CentOS 7.6. Using docker images developers can quickly prototype and build applications without having to be locked into a single system setup or lose valuable time figuring out the dependencies of the underlying software.

Docker with display option#

sudo docker pull mivisionx/ubuntu-18.04:latest
xhost +local:root
sudo docker run -it --device=/dev/kfd --device=/dev/dri --cap-add=SYS_RAWIO --device=/dev/mem --group-add video --network host --env DISPLAY=unix$DISPLAY --privileged --volume $XAUTH:/root/.Xauthority --volume /tmp/.X11-unix/:/tmp/.X11-unix mivisionx/ubuntu-18.04:latest
