Keras：ImportError：`save_model` 需要 h5py，即使代码已经导入了 h5py

Question

我在尝试保存 Keras 模型时遇到了一些麻烦：

这是我的代码：

import h5py
from keras.models import load_model

try:
    import h5py
    print ('import fine')
except ImportError:
    h5py = None

left.save('left.h5')  # creates a HDF5 file 'my_model.h5'
left_load = load_model('left.h5')

但即使代码打印'import fine'，我也收到以下错误：

import fine
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-145-b641e79036fa> in <module>()
      8     h5py = None
      9 
---> 10 left.save('left.h5')  # creates a HDF5 file 'my_model.h5'

   2504         """
   2505         from ..models import save_model
-> 2506         save_model(self, filepath, overwrite, include_optimizer)
   2507 
   2508     def save_weights(self, filepath, overwrite=True):

/usr/local/lib/python3.4/dist-packages/keras/models.py in save_model(model, filepath, overwrite, include_optimizer)
     53 
     54     if h5py is None:
---> 55         raise ImportError('`save_model` requires h5py.')
     56 
     57     def get_json_type(obj):

ImportError: `save_model` requires h5py.

Answer 1

确保您使用的是最新版本的 Keras。

此外，keras github 中已报告此错误： https://github.com/fchollet/keras/issues/3426

在 Linux 上：

sudo apt-get install libhdf5
sudo pip install h5py

Answer 2

你试过直接安装h5py吗？ http://docs.h5py.org/en/latest/build.html

尝试运行 pip install h5py
