AttributeError：“NoneType”对象在张量流中没有属性“模块”

Question

我一直在学习 tensorflow，到现在一切都很好。我什至使用 GPU 用 tensorflow 进行了一些计算。但是在运行 import tensorflow as tf 命令时突然出现以下错误：

Traceback (most recent call last):

  File "<ipython-input-6-41389fad42b5>", line 1, in <module>
    import tensorflow as tf

  File "/home/diego/.local/lib/python2.7/site-packages/tensorflow/__init__.py", line 24, in <module>
    from tensorflow.python import *

  File "/home/diego/.local/lib/python2.7/site-packages/tensorflow/python/__init__.py", line 49, in <module>
    from tensorflow.python import pywrap_tensorflow

ImportError: cannot import name pywrap_tensorflow

这很容易修复，我只是重置了控制台。但这很烦人，因为我每次运行脚本后都需要重置控制台。 （即使脚本只是“import tensorflow as tf”）

当我用 F5 运行整个脚本时，我得到了一个不同的错误，即使唯一的命令是 import tensorflow as tf。 我在 Ubuntu 16.04.3 LTS 上的 spyder 2.7 Python 2.7.12 中运行脚本。

    File "/usr/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 699, in runfile
      execfile(filename, namespace)

    File "/usr/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 81, in execfile
      builtins.execfile(filename, *where)

    File "/home/diego/Desktop/Diego/Trial-Job/Code/pointnet/test2tf.py", line 7, in <module>
      import tensorflow as tf

    File "/home/diego/.local/lib/python2.7/site-packages/tensorflow/__init__.py", line 24, in <module>
      from tensorflow.python import *

    File "/home/diego/.local/lib/python2.7/site-packages/tensorflow/python/__init__.py", line 52, in <module>
      from tensorflow.core.framework.graph_pb2 import *

    File "/home/diego/.local/lib/python2.7/site-packages/tensorflow/core/framework/graph_pb2.py", line 6, in <module>
      from google.protobuf import descriptor as _descriptor

    File "/home/diego/.local/lib/python2.7/site-packages/google/protobuf/__init__.py", line 37, in <module>
      __import__('pkg_resources').declare_namespace(__name__)

    File "/home/diego/.local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 50, in <module>
      from pkg_resources.extern import six

    File "/home/diego/.local/lib/python2.7/site-packages/pkg_resources/extern/__init__.py", line 44, in load_module
      mod = sys.modules[extant]

  AttributeError: 'NoneType' object has no attribute 'modules'

谢谢。

我猜问题出在通配符导入上

from tensorflow.python import *

正如Pep 8 Guide 上所说的那样

应避免通配符导入（来自模块导入 *），因为它们使命名空间中存在哪些名称变得不清楚，从而使读者和许多自动化工具感到困惑 (...)

您是否尝试过按名称导入每个使用的模块并删除通配符导入？
