NGC, pretrained models. Converting pre-trained hdf5 models to caffemodels

Hi,

From the transfer learning toolkit documentations I found out that the pre-trained weights in hdf5 format can be used for training the models so that models need not be trained from scratch. I would like to convert the hdf5 weights to caffemodels so that I can create the caffemodel engine using TensorRT and use it for nvinfer plugins. But I cannot find the “prototxt” for the hdf5 files which is required to convert it to caffemodel. Where can I find the protoxt for those files? I am testing with resnet101.hdf5.

Thank you.

Move this topic into TLT forum because it is related to TLT.

Hi v.snippy,
The hdf5 file cannot be converted to caffemodel. It can be used as a starting point while training via Transfer Learning Toolkit (TLT). Then user can train with their own data to get an etlt model, and then generate a TRT engine.

TLT also provides several Purpose-built models (https://docs.nvidia.com/metropolis/TLT/tlt-getting-started-guide/index.html#purpose_built_models)

You can find pruned etlt files for each kind of Purpose-built models. Then you can generate trt engine via the tool “tlt-converter”. See more in https://docs.nvidia.com/metropolis/TLT/tlt-getting-started-guide/index.html#gen_eng_tlt_converter
