Unsupported ops: TensorScatterAdd, TensorListConcatV2, Rank

[igalkr]

Hi, are the above ops to be supported, or am I running the command incorrectly?
python -m tf2onnx.convert --saved-model saved_model --output model.onnx -v --target tensorrt --tag serve

I am having a very confusing problem with tf2onnx giving me TensorScatterAdd nodes. The tf code I am trying to convert to onnx used tf.tensor_scatter_nd_add. I replaced this with tf.scatter_nd and tf.math.add in the hopes that tf2onnx would stop giving me this TensorScatterAdd node, but I am still getting it. It is almost as if tf2onnx is fusing these two operations for me.

More generally, I am confused why the tf2onnx parser is giving me a node that is not supported by onnx. I would love an explanation of what is going on here!

Yes, TensorScatterAdd, TensorListConcatV2 are not mapped - we'd need to add it.

[igalkr]

What should I do in the meantime? I really need the onnx converted file.

Could you please share the TF code of your model so that we can validate it once there is a fix?

[igalkr]

Hi,
I had to get in contact with our management, we cannot share the code at the moment.

👍 I'd really like to see TensorScatterAdd be added to tf2onnx as well.

Hi @r-remus @igalkr, thanks for your comments!
TensorScatterAdd has added with this PR Add TensorScatterAdd op for opset 16.
You can try to convert it using latest main branch code or waitting for the next tf2onnx release.

It's been over 2 months, so closing this. Feel free to open a new one if the issue still exists.

Tensorflow op [TensorListConcatV2_1: TensorListConcatV2] is not supported

could you please help me?

This op is not supported yet. Please feel free to open a new issue with some details, like code or model, for this requirement so that we can put it into the plan.
