Simple opencv & tensorflow based solution to estimate Faces, Age and Gender on pictures

Project description

Face Age & Gender detection tool

Simple opencv & tensorflow solution to estimate Age and Gender in your next project. Command line or Python DIY style.

Based on and forked from:

Good enough for pet-projects and prototypes, but not ready for production real-life applications


pip3 install py-agender[cpu]  # for the cpu version of TensorFlow
pip3 install py-agender[gpu]  # for the gpu version of TensorFlow

Warning: ~190MB download (pretrained network is heavy).


py-agender PATH_TO_IMAGE


from pyagender import PyAgender

agender = PyAgender() 
# see available options in __init__() src

faces = agender.detect_genders_ages(cv2.imread(MY_IMAGE))
# [
#   {left: 34, top: 11, right: 122, bottom: 232, width:(r-l), height: (b-t), gender: 0.67, age: 23.5},
#   ...
# ]

# Additional options & methods in PyAgender source

Don't forget to download pretrained weights if using source code DIY style.


  • add options (like STDIN input, output formatters etc.) for useful commandline applications
  • add help output
  • train better network with higher image resolution
  • train another (more compact & precise) network architecture


python3 -m unittest 


  • Python 3.5, 3.6, 3.7
  • numpy ~> 1.15
  • Keras ~> 2.2
  • tensorflow or tensorflow-gpu ~> 1.10
  • opencv-python ~> 3.4.2+contrib

Tested on:

  • MacOS 10.13 high Sierra without GPU (you're welcome to update & contribute!)
