解决 TensorFlow 'UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd6' 错误

This error is most likely caused by trying to load a non-UTF-8 encoded file as a text file. The 'load_model' function expects a model file saved in the HDF5 format, not a text file.

To resolve this issue, make sure that the file 'model.h5' is a valid HDF5 file and not a text file. If you are unsure about the format of the file, you can check its contents using a text editor or try opening it with a different application that supports HDF5 files.
