解决“AttributeError: ‘str‘ object has no attribute ‘decode‘”问题

问题描述

在跑代码的时候出现报错提示

Traceback (most recent call last):
  File "multi_detect_Nerual.py", line 4, in <module>
    import BiLSTM.bilstm_speech_seg_predict as nerual_seg
  File "/home/xxx/xxx/xxx/BiLSTM/bilstm_speech_seg_predict.py", line 23, in <module>
    model.load_weights(h5_model_file)
  File "/home/xxx/anaconda3/envs/xxx/lib/python3.7/site-packages/keras/engine/network.py", line 1166, in load_weights
    f, self.layers, reshape=reshape)
  File "/home/xxx/anaconda3/envs/xxx/lib/python3.7/site-packages/keras/engine/saving.py", line 1004, in load_weights_from_hdf5_group
    original_keras_version = f.attrs['keras_version'].decode('utf8')
AttributeError: 'str' object has no attribute 'decode'

问题分析

该报错意思是：属性错误：'str'对象没有'decode'属性

解决方法

最简单的方法，不用修改代码

pip install 'h5py<3.0.0' -i https://pypi.tuna.tsinghua.edu.cn/simple

如下所示，问题解决！
