1.numpy-beginner.ipynb 勘误

[vbirdchong]

In [104]: x = [[1,3,3], [7,5,2]] print(np.argmax(x,axis=0))

这里的axis=0应修改为： axis=1 否则与说明不符

i'm a beginner to jupyter notebooks and data science, numpy... i tried this on my jupyter notebook:

"""import numpy as np a= np.array([1,2,3,4]) print(a)"""

and it showed me this error:

NameError Traceback (most recent call last) in ----> 1 import numpy as np 2 a= np.array([1,2,3,4]) 3 print(a)
