在Python3中导入模块时出错

我试图顺利地从Python2.7过渡到Python3.X（3.5.2）。这是一个分为两步的问题，所以我试图把它说清楚

1.我用

import numpy as np

（我先安装了一个

python3-mppip-installnumpy

），但收到了以下错误消息

  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/numpy/__init__.py", line 180, in <module>
    from . import add_newdocs
  File "/usr/lib/python2.7/dist-packages/numpy/add_newdocs.py", line 13, in <module>
    from numpy.lib import add_newdoc
  File "/usr/lib/python2.7/dist-packages/numpy/lib/__init__.py", line 8, in <module>
    from .type_check import *
  File "/usr/lib/python2.7/dist-packages/numpy/lib/type_check.py", line 11, in <module>
    import numpy.core.numeric as _nx
  File "/usr/lib/python2.7/dist-packages/numpy/core/__init__.py", line 14, in <module>
    from . import multiarray
ImportError: cannot import name 'multiarray'

非常感谢。

您的.bashrc中绝对不应该有这些行。移除它们并开始一个新的外壳

不，您需要重新安装Python3所需的模块

 # added by me for the python import module installed outside anaconda2 (i.e.: pygtk)

export PYTHONPATH="${PYTHONPATH}:/usr/lib/python2.7/dist-packages/"
export PYTHONPATH="${PYTHONPATH}:/usr/lib/python2.7/dist-packages/glib/"
