python-potion 0.2.1.post0

Live video inference

Potion

Live video inference tool which relies on VALI. Use it to run the inference on local and network streams. It uses double queue (compressed + reconstructed) in order not to miss a single frame if inference is slow.

As for early version (0.2 for now) it is only tested with densenet.

Install:

pip install python_potion

Usage example:

python3 -m python_potion \
  -i http://media.sever/rtsp_stream \
  -t 10 \
  -gpu_id 0 \
  -d dump \
  -m densenet_onnx \
  -x 12 \
  -u 0.0.0.0:8001
