python如何查看hdf5文件

# 读取HDF5文件中的所有数据集

def traverse_datasets(hdf_file):

    import h5py

    def h5py_dataset_iterator(g, prefix=''):

        for key in g.keys():

            item = g[key]

            path = '{}/{}'.format(prefix, key)

            if isinstance(item, h5py.Dataset): # test for dataset

                yield (path, item)

            elif isinstance(item, h5py.Group): # test for group (go down)

                yield from h5py_dataset_iterator(item, path)

    with h5py.File(hdf_file, 'r') as f:

        for (path, dset) in h5py_dataset_iterator(f):

            print(path, dset)

    return None

# 传入路径即可

traverse_datasets('datasets/train_catvnoncat.h5')
