python导入在脚本中不起作用[重复]

Question

当我进入 python shell 并尝试导入例如 numpy 或 tensorflow 时，没有错误，但是当我运行导入 numpy 的脚本时，它会抛出此错误：

它更早地工作。我正在使用 Windows 10 x64、Python 3.5.2。我也试过 ubuntu 17，同样的情况。此外，当我在执行脚本后进入 python shell 时，导入会给我同样的错误，直到我重新启动，在我的情况下，powershell。

您有一个名为 org.py 的本地文件，它隐藏了一个可选的内置包（仅在 Jython 中使用）。

来自您的回溯：

  File "C:\Python3\lib\site-packages\numpy\core\numeric.py", line 37, in 
    import pickle
  File "C:\Python3\lib\pickle.py", line 93, in 
    from org.python.core import PyStringMap
  File "C:\Users\Jakub\desktop\Nowy\workspace\python\org.py", line 2, in <module>
    from tensorflow.examples.tutorials.mnist import input_data

C:\Users\Jakub\desktop\Nowy\workspace\python\org.py 不是 pickle 模块寻找的 Jython 包。

您只会在运行脚本时看到此异常，因为您的脚本所在的目录（此处为C:\Users\Jakub\desktop\Nowy\workspace\python）会自动添加到sys.path。

属性错误是循环导入引起的； numpy 导入 pickle 再次导入您的 org 脚本，该脚本导入 numpy，但该模块尚未完成所有导入，因此此时缺少名称。
