H5py存储字符串列表列表

问题描述

在h5py中是否有可能创建一个由字符串列表组成的数据集.我试图创建一个可变长度的嵌套数据类型，但这导致我的python解释器出现分段错误.

Is there a possibility in h5py to create a dataset which consists of lists of strings. I tried to create a nested datatype of variable length, but this results in segmentation fault in my python interpreter.

def create_dataset(h5py_file):
    data = [['I', 'am', 'a', 'sentecne'], ['another', 'sentence']]
    string_dt = h5py.special_dtype(vlen=str)
    nested_dt = h5py.special_dtype(vlen=string_dt)
    h5py_file.create_dataset("sentences", data=data, dtype = nested_dt)

推荐答案

如果您不想编辑hdf5文件(并可能使用更长的字符串)，也可以简单地使用:

If you don't intend to edit the hdf5 file (and potentially use longer strings), you can also simply use:

h5py_file.create_dataset("sentences", data=np.array(data, dtype='S'))
