Loading a prebuilt caffe model in pytorch 1.0

I heard that there is some good integration of caffe and pytorch with the 1.0 release. I am trying to use the modified GoogleLeNet model that has been trained on the Compcars dataset. The pretrained caffe model and the weights are available here: https://gist.github.com/bogger/b90eb88e31cd745525ae

So, basically what is available is the prototxt model definition file and the caffemodel weights file. So, I was looking into the documentation for pytorch 1.0 and came across the following tutorial: https://pytorch.org/tutorials/advanced/super_resolution_with_caffe2.html

I also saw some converters online for converting the caffemodel file to PTH. I was wondering if there is something built into pytorch 1.0 to sort of somehow take the caffe model definition and weight files and generate the model from this?

Hi,

You can always use ONNX to do caffe2 -> onnx -> pytorch. But people usually do the opposite :smiley: and there is no special integration to run caffe2 models in pytorch.

Thanks for that. Unfortunately, this model seems to be using an older version of caffe. I will investigate on what I can do. My issue is that I need to do some transfer learning on this model and would like to change it later as well. So hoping to find a convenient way to do this.
