python – `ImportError：从scikit中导入时无法导入名称_remove_dead_weakref`

问题描述

我在调用python脚本时收到此错误：

Traceback (most recent call last):
  File "/path/t/file/file.py", line 61, in <module>
    from sklearn.externals import joblib
  File "/anaconda2/lib/python2.7/site-packages/sklearn/__init__.py", line 20, in <module>
    import logging
  File "/anaconda2/lib/python2.7/logging/__init__.py", line 26, in <module>
    import sys, os, time, cStringIO, traceback, warnings, weakref, collections
  File "/anaconda2/lib/python2.7/weakref.py", line 14, in <module>
    from _weakref import (
ImportError: cannot import name _remove_dead_weakref
Failed to load file

如错误日志中所述,当我导入时会发生这种情况：

from sklearn.externals import joblib

笔记

注1：
单独调用import sklearn也会产生此错误.

笔记2：
在没有任何其他import语句的情况下运行,并且文件中的其余代码被注释掉也会产生错误

注3：
Objective-C代码通过Python C API(https://docs.python.org/2/c-api/index.html)调用此python文件.
这在具有完全相同规格和操作系统的另一台机器上完美运行(请参阅下面的详细信息).

注4：
如果我从终端调用Python然后从sklearn.externals导入joblib导入sklearn OR(没有从objective-C调用),则没有错误

注5：
我认为我没有安装任何虚拟环境.我试过在终端上调用pyenv,pyvenv和virtualenv.总是得到-bash：pyvenv：命令找不到

细节

我试过的两台机器都是MacBook Pro,运行Mac OS 10.13的规格相同. (代码适用于其中一个而另一个则失败)

我在代码失败的机器上尝试了这个：

我已经在(a)终端上的python CLI上的可执行文件AND(b)调用的脚本中添加了以下行：

print ">>>>>>>>>"+str(sys.executable)
print ">>>>>>>>>"+str(sys.version)
print "++++++++++++++++++++++++++++++++++++++++++++++++++++"
for p in sys.path: 
    print p

脚本输出失败：

基本上,获得相同的东西,除了版本,并且我(显然)也在搜索路径中看到.py文件的路径.

最佳答案 尝试卸载,然后重新安装您的包：

conda卸载scikit-learn
