katnip.model.low_level.encoder module¶

Extensions to Kitty’s encoders.

This module contain encoders that were excluded from Kitty because they are too esoteric or because they require external dependencies that might be harder to install on some platforms.

External dependencies that are not installed by default: pycrypto
