AttributeError：'模塊'對象沒有任何屬性'grd'

Question

我知道這已經被問過很多次在此網站上，但沒有任何解決方案對我有幫助。我運行下面的腳本給我的錯誤標題：

import numpy as np 
import fatiando as ft 

shape = (41, 41) 
x, y = ft.grd.regular((-10, 10, 30, 50), shape) 
height = 800 - 1000*ft.utils.gaussian2d(x, y, 3, 1, x0=0, y0=37) 
rel = -7000*ft.utils.gaussian2d(x, y, 3, 5, x0=0, y0=40) 
thick = height - rel 
dens = 1900*np.ones_like(thick) 
data = np.transpose([x, y, height, thick, dens]) 
with open('layers.txt', 'w') as f: 
    f.write("# Synthetic layer model of sediments and topography\n") 
    f.write("# Columns are:\n") 
    f.write("# lon lat height thickness density\n") 
    np.savetxt(f, data, fmt='%g') 
ft.vis.figure(figsize=(4, 3)) 
ft.vis.title('Depth of sediments [m]') 
ft.vis.axis('scaled') 
ft.vis.pcolor(x, y, rel, shape) 
ft.vis.colorbar() 
ft.vis.savefig('depth.png') 
ft.vis.figure(figsize=(4, 3)) 
ft.vis.title('Topography [m]') 
ft.vis.axis('scaled') 
ft.vis.pcolor(x, y, height, shape) 
ft.vis.colorbar() 
ft.vis.savefig('topography.png') 
ft.vis.figure(figsize=(4, 3)) 
ft.vis.title('Thickness of sediment layer [m]') 
ft.vis.axis('scaled') 
ft.vis.pcolor(x, y, thick, shape) 
ft.vis.colorbar() 
ft.vis.savefig('thickness.png') 
ft.vis.show() 

這個腳本是不是我自己的創作，但我已經安裝（Tesseroids）程序，所以我不預先包裝的演示腳本不知道爲什麼我在使用時出現錯誤。我已經安裝了fatiando。

Answer 1

看來，fatiando.grd已被重命名爲fatiando.gridder。進口OK對我來說，如果我做這種方式：

import numpy as np 
import fatiando as ft 
from fatiando import gridder 

shape = (41, 41) 
x, y = gridder.regular((-10, 10, 30, 50), shape) 

我發現，在該項目的github repository的變化。
