ValueError：numpy.dtype的大小错误，请尝试重新编译

Question

我刚刚在python 2.7上安装了pandas和statsmodels软件包，当我尝试“将pandas导入为pd”时，出现此错误消息。有人可以帮忙吗？谢谢！！！

Answer 1

对我来说（Mac OS X Maverics，Python 2.7）easy_install --upgrade numpy帮助。之后，您可以使用pip安装最新软件包pandas，scikit-learn等：pip install pandas

Answer 2

我发现它是一个过时或不匹配的简单版本，并通过以下方式修复：pip install --upgrade numpypip install --upgrade scipypip install --upgrade pandas或者可以使用一种衬板：pip install --upgrade numpy scipy pandas
