python - 如何升级 NumPy？

Question

当我使用 Homebrew 安装 OpenCV 时(brew)，每当我运行这个命令来测试 python -c "import cv2":

RuntimeError: module compiled against API version 9 but this version of numpy is 6
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: numpy.core.multiarray failed to import

我尝试升级 NumPy，但这令人困惑:

>>> import numpy
>>> print numpy.__version__
1.6.1

当我运行 brew 升级 NumPy 时，我遇到了这个问题:

brew install -u numpy
Warning: numpy-1.9.1 already installed

当我卸载它时:

sudo pip install numpy
Requirement already satisfied (use --upgrade to upgrade): numpy in ./anaconda/lib/python2.7/site-packages

我关注了this question并删除了Anaconda从我的 mac。

pip install numpy
Requirement already satisfied (use --upgrade to upgrade): numpy in /Library/Python/2.7/site-packages

但一切都没有改变。如何将 NumPy 版本链接到 OpenCV？

Answer 1

如果您已经拥有旧版本的 NumPy，请使用:

pip install numpy --upgrade

如果还是不行，试试:

pip install numpy --upgrade --ignore-installed
