Getting issue while importing detectron2.export.api.Caffe2Tracer

[vivekkaushik1992]

I am importing Caffe2Tracer from detectron2.export.api.Caffe2Tracer. In document old version format is mentioned and do correct that.

Once importing this, Getting Caffe2.porto "metanet_pb2" not found.

Can you share proper instruction to follow to export ONNX model from Detectron2@v0.6.

Instructions To Reproduce the Issue:

1> Install latest Detectron2
2> Import detectron2.export.api.Caffe2Tracer

import module not found " metanet_pb2" in " caffe2.porto "

I think's there is some issue with incompatibility of Torch version and Detectron version.

With Pytorch version 1.12.0 installed with conda, the same error occurs when running:

from caffe2.proto import caffe2_pb2

I think it's the problem with PyTorch, not Detectron2.

Downgrading PyTorch to 1.10.1 fixed the error for me

Caffe2 is no longer supported by latest pytorch.
