Question

I'm running this model from AWS instance of type P2.xlarge. It is giving an error as:

Exception in thread Thread-16:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner

File "/usr/lib/python2.7/threading.py", line 754, in run

File "/home/ubuntu/tensorflow/models/summarization/textsum/data.py", line 109, in ExampleGen
example_str = struct.unpack('%ds' % str_len, reader.read(str_len))[0]
MemoryError

NVIDIA status-

ubuntu@ip-172-31-28-161:~$ lspci | grep -i nvidia

00:1e.0 3D controller: NVIDIA Corporation GK210GL [Tesla K80] (rev a1)

What is the solution for this?

If I replace str_len = struct.unpack('q', len_bytes)[0] with str_len = struct.unpack('Bi', len_bytes)[0] then this error disappears and new error come up as:

Exception in thread Thread-15:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner
self.run()
File "/usr/lib/python2.7/threading.py", line 754, in run

File "/home/mindstix/bazel/models/Summarizer/textsum/batch_reader.py", line 136, in _FillInputQueue

File "/home/mindstix/bazel/models/Summarizer/textsum/batch_reader.py", line 248, in _TextGenerator
article_text = self._GetExFeatureText(e, self._article_key)
File "/home/mindstix/bazel/models/Summarizer/textsum/batch_reader.py", line 265, in _GetExFeatureText
return ex.features.feature[key].bytes_list.value[0]
IndexError: list index (0) out of range

If I print example_str then the value displays on screen. But when I try to print ex.features.feature[key].bytes_list.value it returns blank.

what should be done to resolve all this?

This is the code steps I am following:

>>> 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] 
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IndexError: list index (0) out of range

Answer 1

I got stacked with the same problem. But the reason is that I use the raw text file for test. It is the transferred binary file should be used. I'm not sure whether your situation is the same with me.
