我正在尝试为 TextSum 模型创建自己的训练数据。据我了解,我需要将我的文章和摘要放入二进制文件(在 TFRecords 中)。但是,我无法从原始文本文件创建自己的训练数据。我不太清楚格式,所以我尝试使用以下代码创建一个非常简单的二进制文件:
files = os.listdir(path)
writer = tf.python_io.TFRecordWriter("test_data")
for i, file in enumerate(files):
content = open(os.path.join(path, file), "r").read()
example = tf.train.Example(
features = tf.train.Features(
feature = {
'content': tf.train.Feature(bytes_list=tf.train.BytesList(value=[content]))
}
)
)
serialized = example.SerializeToString()
writer.write(serialized)
我尝试使用下面的代码来读出这个 test_data 文件的值
reader = open("test_data", 'rb')
len_bytes = reader.read(8)
str_len = struct.unpack('q', len_bytes)[0]
example_str = struct.unpack('%ds' % str_len, reader.read(str_len))[0]
example_pb2.Example.FromString(example_str)
但我总是收到以下错误:
File "dailymail_corpus_to_tfrecords.py", line 34, in check_file
example_pb2.Example.FromString(example_str)
File "/home/s1510032/anaconda2/lib/python2.7/site-packages/google/protobuf/internal/python_message.py", line 770, in FromString

new_pos = local_SkipField(buffer, new_pos, end, tag_bytes)

我不知道出了什么问题。如果您有任何解决此问题的建议,请告诉我。
