I was following this guide to convert my simple model from PyTorch to ONNX to TensorFlow to TensorFlow Lite for deployment. But I received the following warnings on TensorFlow 2.3.0:
2021-08-19 12:01:09.231710: W tensorflow/python/util/util.cc:348] Sets are not currently considered sequences, but this may change in the future, so consider avoiding using them.

On TensorFlow 2.5.0:

Other versions (The onnx-tf was from PyPI instead from their latest GitHub):
numpy == 1.19.5
onnx == 1.10.1
onnx_tf == 1.8.0
tensorflow_gpu == 2.5.0
torch == 1.9.0
Although the model gets converted without any errors and I’ve checked the ONNX graph and it looks correct and I’ve also tried inference with dummy values and that also works but I want to be sure that the model doesn’t break after deployment because of something I missed in these warnings.
