CALC2.0

Convolutional Autoencoder for Loop Closure 2.0.

To get started, download the COCO dataset and the "stuff" annotations, then run dataset/gen_tfrecords.py. Make sure to unzip the tar in the dataset directory first. Doing this will generate the sharded tfrecord files as well as loss_weights.txt.

After that you can train with calc2.py.

Check the --mode options in calc2.py to see what else you can do, like PR curves and finding the best model in a directory.
