Hi @kempj, Glow has multiple front ends. That is, we can load models from ONNX or Caffe2 protobufs, or through TorchScript from PyTorch (torch_glow). Or you could even write your model directly in C++ with our C++ APIs if you wanted .
torch_glow is under active development/is less mature than our ONNX and Caffe2 protobuf loaders. If you have problems with torch_glow, another path from PyTorch to Glow is to export your model to ONNX and then load into Glow.
