Julia linspace出错:ERROR: UndefVarError: linspace not defined

安装了PyPlot 和 PyCall,但是include(“test.jl”)的时候弹出ERROR: UndefVarError: linspace not defined的错误!请问各位,这该如何解决?

python我也是有安装的,版本是3.6.5。难道是要和python.exe进行什么关联操作吗?


好讨厌报这个linspace的错误!这是要让我放弃学Julia语言的节奏吗?

using PyCall
@pyimport numpy as np
n = 100
u = np.linspace(0,2*pi,n)

结果:

100-element Array{Float64,1}:
