Question

python 2.7.13 / h5py 2.9.0

我尝试用h5py查看HDF5文件中的属性。

当我使用foo.attrs.values（）或foo.attrs ['attribute_keys']

时发生错误

IOError：无法读取属性（转换路径没有适当的功能）

我可以使用attrs.keys（）访问密钥

但是attrs.values（），attrs.items（）无效。

#working in shell

>>> f=h5py.File('D:\read\sample.h5','r')

>>> f.attrs.keys()
[u'_NCProperties', u'satellite_name', u'instrument_name', u'data_processing_center', u'data_processing_mode', u'channel_spatial_resolution'... so on]

>>> f.attrs.values()
