KeyError: <QuantScheme.post_training_tf_enhanced: 2>

When running the following code：

I encountered the error KeyError: <QuantScheme.post_training_tf_enhanced: 2>. I have checked /root/autodl-tmp/aimet-1.32.0/TrainingExtensions/common/src/python/aimet_common/defs.py, and the code contains the corresponding QuantScheme.post_training_tf_enhanced. Why is this error still occurring?
