导入模块时出错

Question

I'm getting the following error when importing modules in python. I'm using jupyter notebook (python 2). I've searched through the internet but still can't quite figure out why. Any help would be so much appreciated.

Here's the code:

import numpy as np
from pandas import Series,DataFrame
import pandas as pd
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-e4e9959b303a> in <module>()
----> 1 import numpy as np
  2 from pandas import Series,DataFrame
  3 import pandas as pd

 /Users/...filepath.../Python/data_analysis/numpy.pyc in <module>()
      17 
      18 import numpy as np
 ---> 19 from numpy.random import randn
      20 
      21 

      ImportError: No module named random

I've tried adding import random to the above code (before the other modules) and it still gives the same error. Could this be due to the version of gfortran on my system? I have version 4.9.2

Since I dont have complete code, just tried using import statements.

If we use np as per @John
import numpy as np
from np.random import randn

I am getting
from np.random import randn
ImportError: No module named np.random

I am not getting any error if I import randn from numpy.random

import numpy as np
from numpy.random import randn
print "randn1= ", randn()

from numpy.random import rand
print "rand1= ", rand()

Its working for me with output as below,

randn1=  0.147667079884  
rand1=  0.243935746205  

You can also try to use np.random.randn() and np.random.rand() directly.

import numpy as np
print "randn2= ", np.random.randn()
print "rand2= ", np.random.rand()

I get :
randn2= -0.22571513741
rand2= 0.486507681046
