Hi Kevin,
Thanks for your reply. I am trying to adapt the model to tf1, e.g., 'NonMaxSuppressionV5' in tf2 to ' NonMaxSuppressionV3', which is supported by tensorflow frontend. The computational graph .pb file seems fine now. However, when running ~~~~ mod, params = relay.frontend.from_tensorflow(graph_def, layout=layout, shape=shape_dict) ~~~~ still get three unsupported operators related to the pre-processing the input data. ~~~~ NotImplementedError: The following operators are not implemented: {'TensorListStack', 'TensorListReserve', 'While'} ~~~~ Thanks again. --- [Visit Topic](https://discuss.tvm.ai/t/tensorflow-frontend-support-for-tensor-frontend-new-operators/6971/3) to respond.
