 ## Detailed Python API documentation <a name="run"/>
 The main function of fastdup is `run`. It works by extracting short feature vectors from each image, clsutering the images together using a nearest neighbor model which computes similarities of pairs of images. Then a graph is formed to deduce the network structure of local similarities. The input/ outputs are described below in the section Input/Output.

 - It is recommneded to debug in a python shell (and not in a Jupyter notebook)
 - Run with `verbose=1` to get additional traces
 - Run with `num_images=10` to run on a small subset of your data before running on the full dataset.
