这个错误应该问题不大，你试试下面的代码能正常运行吗？

import h5py

f = h5py.File(u'中文', 'w')

我觉得是那个测试本身的文件名有问题吧。

我也试了一下，问题出在同样的位置

C:\Python26\lib\site-packages\h5py\h5f.pyd in h5py.h5f.create (h5py\h5f.c:1414)(

)

IOError: Invalid argument (Internal error (too specific to document in detail):

System error message)

不过仿照pdf中的例子

f=h5py.File('tmp.hdf5')

及一系列操作没有什么问题。

邹建：which pdf ？ 版主的<<用python做科学计算吗>>？

是的，

其中的:实战—数据和文件—读写HDF5文件

里面提及了这个库的一些用法。
