python numpy 或 scipy 错误

我想使用 Python 工作。当我导入 scipy 或 numpy 时，它显示以下错误：

saikat@saikat:~/Downloads/Python-2.7.15$ python
Python 2.7.14 |Anaconda, Inc.| (default, Dec  7 2017, 17:05:42) 
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy
>>>

但是当我使用这个命令时：

sudo pip install numpy scipy

表明：

saikat@saikat:~/Downloads/Python-2.7.15$ sudo pip install numpy scipy

我应该怎么办？

conda您有 Anaconda Python 而不是系统 Python 版本。由于您使用 Anaconda，因此您的软件包应使用或 Anacondapip版本安装。使用base默认 Anaconda 安装的环境，Numpy 和 Scipy 已安装，如果没有：

conda install numpy scipy
