AttributeError: 'FuncGraph'

Hi,

I am using the below command to convert a tf-nlp model to onnx. It has a custom-ops built in.

!/anaconda/envs/onnxet/bin/python3.10 -m tf2onnx.convert --saved-model {checkpoint_path} --output {onnx_model_output_path} --extra_opset ai.onnx.contrib:1 --custom-ops StringStrip:ai.onnx.contrib

The code has been working fine with no issue, but for some reason, not anymore. Here is the error I get:

Execute tf2onnx.convert from saved model ./01_nlprrs_pg_01_NoGmail_tf/ to output nlprrs_pg_NoTop20.onnx /anaconda/envs/onnxet/lib/python3.10/runpy.py:126: RuntimeWarning: 'tf2onnx.convert' found in sys.modules after import of package 'tf2onnx', but prior to execution of 'tf2onnx.convert'; this may result in unpredictable behaviour warn(RuntimeWarning(msg)) 2023-09-14 05:38:25,073 - WARNING - '--tag' not specified for saved_model.

Did you mean: 'captures'?

I would appreciate any advice. Mo

Could you please try the latest tf2onnx version? This is an issue brought by recent TensorFlow versions and was fixed already.
