solution:demo-obj-detection-coco-tf-cpu-webcam-rpi4 (v1.5.0)

Portable solution description  

Install and run this solution on your platform in several simple steps. Our goal is to make it simpler to reproduce results from research papers, participate in crowd-benchmarking, and enable "live" papers.
Don't hesitate to get in touch if you encounter any issues or would like to discuss this community project!

Check the prerequisites for your system  

Install manually from the command line (to be automated in the future):

* https://github.com/mlperf/inference/blob/master/v0.5/classification_and_detection/optional_harness_ck/detection/tf-py/README.md

This CK solution demo was prepared by Grigori Fursin and Hervé Guillou.

Ubuntu (need those deps to rebuild COCO API):

 sudo apt update
 sudo apt install git wget libz-dev curl cmake
 sudo apt install gcc g++ autoconf autogen libtool

On some occasion we need to install extra deps:
 sudo apt install -y libsm6 libxext6 libxrender-dev

Install cBench (docs)

Install cBench from the command line (a small Python library to manage CK solutions):
pip3 install cbench
 or 
python3 -m pip install cbench
 or
pip install cbench 
Note that you may need to add the --user flag if you install in your user space, i.e. "python3 -m pip install cbench --user"

Init this solution with the portable workflow on your machine

Run manually from your command line (cBench will attempt to automatically adapt this workflow to your system - you may need to press Enter several times to select default answers for some questions):
cb init demo-obj-detection-coco-tf-cpu-webcam-rpi4

Start cBench (status: disconnected)

cb start
