"IOError: Unable to read attribute (no appropriate function for conversion path)" when access to attribute with h5py

Question

python 2.7.13 / h5py 2.9.0

我尝试使用 h5py 查看 HDF5 文件中的属性。

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

时出现错误

IOError：无法读取属性（转换路径没有合适的函数）

我可以使用 attrs.keys()

访问密钥

但是 attrs.values()、attrs.items() 没有用。

#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()

Traceback (most recent call last):
