我正在从P2.xlarge类型的AWS实例运行此模型。它给出了一个错误：
Exception in thread Thread-16:

这是什么解决方案？
如果我将str_len = struct.unpack('q', len_bytes)[0]替换为str_len = struct.unpack('Bi', len_bytes)[0]
然后这个错误就消失了，新错误出现了：
Exception in thread Thread-15:
Traceback (most recent call last):

return ex.features.feature[key].bytes_list.value[0]
IndexError: list index (0) out of range
如果我打印example_str，则屏幕上会显示该值。但是当我尝试打印ex.features.feature[key].bytes_list.value时，它会返回空白。
应该采取什么措施来解决这一切？
这是我遵循的代码步骤：
>>> import tensorflow as tf
>>> import struct
>>>from tensorflow.core.example import example_pb2
>>> reader = open('data/training-1', 'rb')
>>> len_bytes = reader.read(8)
>>> str_len = struct.unpack('q', len_bytes)[0]
>>> str_len
2335523720558635124
>>> example_str = struct.unpack('%ds' % str_len, reader.read(str_len))[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
MemoryError
>>> str_len = struct.unpack('Bi', len_bytes)[0]
>>> str_len
116
>>> example_str = struct.unpack('%ds' % str_len, reader.read(str_len))[0]
>>>e = example_pb2.Example.FromString(example_str)
>>> e.features.feature['article'].bytes_list.value
<google.protobuf.pyext._message.RepeatedScalarContainer object at 0x7fc25c9325a8>
>>> e.features.feature['article'].bytes_list.value[0]

答案 0 :(得分：1)
我遇到了同样的问题。但原因是我使用原始文本文件进行测试。它应该是使用传输的二进制文件。我不确定你的情况是否和我一样。
