python - 导入错误 : DLL load failed when importing Numpy installed in conda virtual environment

Question

在 Windows 中，我使用命令创建了一个 Conda 虚拟环境

conda create -n test python=2.7 pandas scipy matplotlib numpy

创建后，我激活了虚拟环境并进入了 python 解释器。尝试导入 numpy 时，出现以下错误:

>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Anaconda3\envs\test\lib\site-packages\numpy\__init__.py", line 180, in <module>
    from . import add_newdocs
  File "C:\Anaconda3\envs\test\lib\site-packages\numpy\add_newdocs.py", line 13, in <module>
    from numpy.lib import add_newdoc
  File "C:\Anaconda3\envs\test\lib\site-packages\numpy\lib\__init__.py", line 8,
 in <module>
    from .type_check import *
  File "C:\Anaconda3\envs\test\lib\site-packages\numpy\lib\type_check.py", line 11, in <module>
    import numpy.core.numeric as _nx
  File "C:\Anaconda3\envs\test\lib\site-packages\numpy\core\__init__.py", line 14, in <module>
    from . import multiarray
ImportError: DLL load failed: The specified module could not be found.

有什么想法吗？谢谢!

卸载并重新安装 numpy。

pip uninstall numpy
pip install numpy

然后再次尝试导入，它应该可以工作。我就是这么做的
