# Deep Learning Model Convertors

Note: **This is not one convertor for all frameworks, but a collection of different converters.** Because github is an open source platform, I hope we can help each other here, gather everyone's strength.

Because of these different frameworks, the awesome convertors of deep learning models for different frameworks occur. It should be noted that I did not test all the converters, so I could not guarantee that each was available. But I also hope this convertor collection may help you!

The sheet below is a overview of all convertors in github (not only contain official provided and more are user-self implementations). I just make a little work to collect these convertors. Also, hope everyone can support this project to help more people who're also crazy because of various frameworks.

This repo contains tools to convert Caffe models into a format compatible with the neon deep learning library. The main script, "decaffeinate.py", takes as input a caffe model definition file and the corresponding model weights file and returns a neon serialized model file. This output file can be used to instantiate the neon Model object, which will generate a model in neon that should replicate the behavior of the Caffe model.

### kuangliu/mocha

Convert torch model to/from caffe model easily.

### szagoruyko/loadcaffe

Convert caffe model to a Torch nn.Sequential model.

## Keras convertor

**Convert to Keras model**.

### pierluigiferrari/caffe_weight_converter

This is a Caffe-to-Keras weight converter, i.e. it converts `.caffemodel`

weight files to Keras-2-compatible HDF5 weight files. It can also export `.caffemodel`

weights as Numpy arrays for further processing.

This converter converts the weights of a model only (not the model definition), which has the great advantage that it doesn't break every time it encounters an unknown layer type like other converters to that try to translate the model definition as well. The downside, of course, is that you'll have to write the model definition yourself.

The repository also provides converted weights for some popular models.

### qxcv/caffe2keras

Note: This converter has been adapted from code in Marc Bolaños fork of Caffe. See acks for code provenance.

This is intended to serve as a conversion module for Caffe models to Keras models.

Please, be aware that this module is not regularly maintained. Thus, some layers or parameter definitions introduced in newer versions of either Keras or Caffe might not be compatible with the converter. Pull requests welcome!
