RuntimeError:针对API版本0xc编译的模块,但此版本的numpy为0xb

Question

我正在尝试学习机器学习,但我无法解决以下错误.

[我的环境]

• Mac High Sierra 10.13.2
• Python3.4.5
• Numpy1.13.3

[命令]

$ python3 -c "import jupyter, matplotlib, numpy, pandas, scipy, sklearn"

[错误]

RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
Traceback (most recent call last):
  File "/Users/uekyo/ml/env/lib/python3.4/site-packages/pandas/__init__.py", line 26, in <module>
    from pandas._libs import (hashtable as _hashtable,
  File "/Users/uekyo/ml/env/lib/python3.4/site-packages/pandas/_libs/__init__.py", line 4, in <module>
    from .tslib import iNaT, NaT, Timestamp, Timedelta, OutOfBoundsDatetime
  File "pandas/_libs/tslib.pyx", line 1, in init pandas._libs.tslib
ImportError: numpy.core.multiarray failed to import

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Users/uekyo/ml/env/lib/python3.4/site-packages/pandas/__init__.py", line 35, in <module>
    "the C extensions first.".format(module))
ImportError: C extension: numpy.core.multiarray failed to import not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace --force' to build the C extensions first.

[我试过的东西]

我明白numpy是错的.所以我尝试了下面的东西,但错误仍然出现.

〜1〜

sudo mv /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy_old

〜2〜

pip3 uninstall numpy
pip3 install numpy  -I

谢谢.

看起来这是由于pandas version higher than 0.21.0和numpy version 1.13.3由拉TensorFlow打得不好togather.以下是我在最后修复它的方法:

# ipython
Python 2.7.6 (default, Nov 23 2017, 15:49:48)
Type "copyright", "credits" or "license" for more information.

IPython 4.2.0 -- An enhanced Interactive Python.

最有可能是由于numpy版本太低；这个解决了我的问题：

pip3 install "numpy == 1.15.0" --user 

conda安装无法解决，因为当前它只有numpy版本1.13.1，但是可能是由于我选择的镜像站点不是最新的
