Hi,
This is a known issue in tensorflow-2.1.0+nv20.4-cp36-cp36m-linux_aarch64.whl.
A workaround is to comment out the version checker in uff parser dierctly.
/usr/lib/python3.6/dist-packages/uff/converters/tensorflow/conversion_helpers.py
...
# if tf.__version__ != tf_supported_ver:
# print("NOTE: UFF has been tested with TensorFlow " + str(tf_supported_ver) + ".")
# print("WARNING: The version of TensorFlow installed on this system is not guaranteed to work with UFF.")
...
Thanks.
