py39-tensorflow @2.5.0_0: Symbol not found: __ZN10tensorflow4data17FinalizeDatasetOp15kHasCapturedRefE

[p-bro]

After successfully installing py39-tensorflow (import tensorflow as tf), I get the following error when I attempt to import tensorflow in python (full context below):

ImportError: dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so, 6): Symbol not found: __ZN10tensorflow4data17FinalizeDatasetOp15kHasCapturedRefE
  Referenced from: /opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so
  Expected in: flat namespace
 in /opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so

This is unexpected behaviour. A similar error message is reported in #60663, but during build, not run phase.

Further checking: Deactivating the py39-tensorflow port and using pip to install tensorflow locally resolves this problem:

sudo port deactivate py39-tensorflow
pip install --upgrade tensorflow
python -c "import tensorflow as tf;print(tf.reduce_sum(tf.random.normal([1000, 1000])))"

provides the expected tensor as an answer, not the error message.
