np is not defined after importing numpy-CodePudding

import numpy as np
np.array([1,2,3,4])

Why I'm having this error

NameError Traceback (most recent call last) ~\AppData\Local\Temp/ipykernel_2304/609253908.py in ----> 1 np.array([1,2,3,4])

NameError: name 'np' is not defined

CodePudding user response：

Your error code says that np.array([1, 2, 3, 4]) is in line 1 so you are trying to use it before importing, you need to import numpy first, as shown in your question.

CodePudding user response：

You can just go with numpy

import numpy
numpy.array([1,2,3,4])

Have you installed or updated numpy? Try this once in your terminal.

>>> pip install numpy
