AWS EC2 上的 Numpy 错误

Question

When I try to execute numpy script on AWS EC2, I am getting the following error.

How can I fix this?

[ec2-user@ip-XXX-XX-XX-XX ~]$ python samplenumpy.py
Traceback (most recent call last):
  File "samplenumpy.py", line 2, in <module>
    import numpy as np
ImportError: No module named numpy

But Numpy is already there on EC2:

[ec2-user@ip-XXX-XX-XX-XX ~]$ sudo yum install numpy
Loaded plugins: priorities, update-motd, upgrade-helper
amzn-main                                                | 2.1 kB     00:00
amzn-updates                                             | 2.3 kB     00:00
Package python26-numpy-1.7.2-8.16.amzn1.x86_64 already installed and latest version
Nothing to do

Answer 1

It's a version conflict. check python version in which numpy is installed

You need to run your script with same python version in which numpy is installed.

If you are running your code using python2 then install numpy using command:

pip install numpy

Or if you are running it in python3 then use command :

pip3 install numpy
