MMdnn is a set of tools to help users inter-operate among different deep learning frameworks. E.g. model conversion and visualization. Convert models between Caffe, Keras, MXNet, Tensorflow, CNTK, PyTorch Onnx and CoreML.
MMdnn is a comprehensive and cross-framework tool to convert, visualize and diagnose deep learning (DL) models. The "MM" stands for model management, and "dnn" is the acronym of deep neural network.
Major features include:
Model Search & Visualization
We encourage researchers, developers and students to leverage these projects to boost their AI / Deep Learning productivity.
You can get a stable version of MMdnn by
pip install mmdnn
And make sure to have Python installed or you can try the newest version by
pip install -U git+https://github.com/Microsoft/[email protected]
MMdnn provides a docker image, which packages MMdnn and Deep Learning frameworks that we support as well as other dependencies. You can easily try the image with the following steps:
Install Docker Community Edition(CE)
Pull MMdnn docker image
bash docker pull mmdnn/mmdnn:cpu.small
Run image in an interactive mode
docker run -it mmdnn/mmdnn:cpu.small
Across the industry and academia, there are a number of existing frameworks available for developers and researchers to design a model, where each framework has its own network structure definition and saving model format. The gaps between frameworks impede the inter-operation of the models.
We provide a model converter to help developers convert models between frameworks through an intermediate representation format.
[Note] You can click the links to get detailed README of each framework.
The model conversion between currently supported frameworks is tested on some ImageNet models.
One command to achieve the conversion. Using TensorFlow ResNet V2 152 to PyTorch as our example.
$ mmdownload -f tensorflow -n resnet_v2_152 -o ./ $ mmconvert -sf tensorflow -in imagenet_resnet_v2_152.ckpt.meta -iw imagenet_resnet_v2_152.ckpt --dstNodeName MMdnn_Output -df pytorch -om tf_resnet_to_pth.pth
Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that you have the right to and actually do, grant us the rights to use your contribution. For details, visit https://cla.microsoft.com.
When you submit a pull request, a CLA-bot will automatically determine whether you need to provide a CLA and decorate the PR appropriately (e.g., label, comment). Simply follow the instructions provided by the bot. You will only need to do this once across all repos using our CLA.
The intermediate representation stores the network architecture in protobuf binary and pre-trained weights in NumPy native format.
[Note!] Currently the IR weights data is in NHWC (channel last) format.
We are working on other frameworks conversion and visualization, such as PyTorch, CoreML and so on. We're investigating more RNN related operators. Any contributions and suggestions are welcome! Details in Contribution Guideline.
