我今天在用python写入hdf5的时候，出现了下面的错误：

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)

      5 number_of_features = len(image_feature_files)
      6 for image_arg, image_file in tqdm(enumerate(image_feature_files)):

      8     image_data = file_id.create_dataset('image_features',

ValueError: Not a location (invalid object ID)

然后百度没有搜到答案，我这里弥补一下空缺，错误虽小，但是出现了总会让人头疼。

我的代码为：

print('Writing image features to h5...')
IMG_FEATS = 2048
cnn_extractor='inception'
dataset_file = h5py.File(cnn_extractor +'_image_name_to_features.h5')
number_of_features = len(image_feature_files)
for image_arg, image_file in tqdm(enumerate(image_feature_files)):
    file_id = dataset_file.create_group(image_file)
    image_data = file_id.create_dataset('image_features',
                                        (IMG_FEATS,), dtype='float32')
    image_data[:] = extracted_features[image_arg,:]
    dataset_file.close()

后面发现是因为我在写入h5的时候，迭代的时候close了，所以改的方式就是把close代码放到循环外了哈

print('Writing image features to h5...')
IMG_FEATS = 2048
cnn_extractor='inception'
dataset_file = h5py.File(cnn_extractor +'_image_name_to_features.h5')
number_of_features = len(image_feature_files)
for image_arg, image_file in tqdm(enumerate(image_feature_files)):
    file_id = dataset_file.create_group(image_file)
    image_data = file_id.create_dataset('image_features',
                                        (IMG_FEATS,), dtype='float32')
    image_data[:] = extracted_features[image_arg,:]
dataset_file.close()
