Answer 1

Try to run the script by using the command python3 script_name.py . The reason for the error could be because script is using python 2.7.5 version.

Answer 2

You may have to check your PYTHONPATH

To print the python search path type this in python shell

import sys  
print sys.path

Here you should find the directory containing your numpy library. But if it is missing then manually locate the directory containing numpy library and add it to your python path using this code

sys.path.append('your directory path here')

then try importing again
