1 Introduction to the environment

Deep learning framework version and corresponding python The environment version is as follows ：

TensorFlow2.1.0+keras2.3.1+python36

2 Error message ：

File "D:\Python36\lib\site-packages\keras\engine\saving.py", line 492, in load_wrapper
return load_function(*args, **kwargs)
File "D:\Python36\lib\site-packages\keras\engine\saving.py", line 584, in load_model
model = _deserialize_model(h5dict, custom_objects, compile)
File "D:\Python36\lib\site-packages\keras\engine\saving.py", line 273, in _deserialize_model
model_config = json.loads(model_config.decode('utf-8'))
AttributeError: 'str' object has no attribute 'decode'

3 Problem analysis

In the above environment , load .h5 Deep learning model , The error that the message character cannot be decoded , The probability is that a package version is incompatible . What exactly is incompatible , You can see this sentence from the error message ：

model = _deserialize_model(h5dict, custom_objects, compile)

Current environment pair h5 There is a problem that deserialization cannot be carried out when processing files , Search for information and find ：

When we install tensorflow2.1.0 When , It will be automatically installed for us h5py The version is 3.1.0. However tensorflow2.1.0 Support h5py<3.0.0, This is the root cause of the above error report .
