Question

I'm converting a model made by google research
https://storage.googleapis.com/cloud-tpu-checkpoints/detection/projects/fvlm/r50.zip

after unzip,
python -m tf2onnx.convert --saved-model ./r50 --output model.onnx

it shows
2023-05-16 14:30:30,770 - WARNING - tf2onnx.tf_loader: '--tag' not specified for saved_model. Using --tag serve
2023-05-16 14:31:07,653 - INFO - tf2onnx.tf_loader: Signatures found in model: [serving_default].

Segmentation fault (core dumped)

Can anyone try to convert it and give me some feedback? Thanks a lot.
