Pickle ImportError:没有名为“builtin”的模块__

Question

我试图在python3.6中加载一个（复制的）pickle对象，当我这样做时，__builtin__\r会出现一个导入错误。在

with open('FilePath/FileName.pkl', "rb") as file:
    file = pickle.load(file)

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-36-b39fbab9bab4> in <module>()
      1 with open('FilePath/FileName.pkl', "rb") as file:
----> 2     file = pickle.load(file)

ModuleNotFoundError: No module named '__builtin__\r'

当我在Python2.7中尝试相同的操作时，我再次遇到导入错误，对于__builtin__模块：

   1131         mod = sys.modules[module]
   1132         klass = getattr(mod, name)

ImportError: No module named __builtin__

我导入了builtins（py3.6）和{}（py2.7），但这并没有停止抛出完全相同的错误。
这里的实际问题是什么？而且，__builtin__\r在py36中甚至看起来不是一个真正的包。在

这看起来像是在Windows（和python2）上以文本模式编写pickle。使用文本模式不是一个好主意，因为\n->；\r\n转换会使这种pickle在非Windows或python3上无法读取。在

以二进制模式读取数据，并在loads之前调用.replace(b'\r\n', b'\n')，这可能允许您加载数据，就像在python2上的Windows上重新加载数据并以二进制模式重新调用它一样。在
