几个月前我写的一些代码正在粉碎,并且由于某些原因它不再起作用……简而言之,我使用scipy.interpolate.LinearNDInterpolator对象来插入模型并与数据进行比较.现在,当我尝试使用我想要插值的坐标调用插值器对象时,我收到以下错误：
In [9]: a([[3500,3.5,1.5]]) AttributeError Traceback (most recent call last) <ipython-input-9-91f2103e7a0c> in <module>() ----> 1 a([[3500,1.5]]) /usr/lib64/python2.7/site-packages/scipy/interpolate/interpnd.so in scipy.interpolate.interpnd.NDInterpolatorBase.__call__ (scipy/interpolate/interpnd.c:3133)() /usr/lib64/python2.7/site-packages/scipy/interpolate/interpnd.so in scipy.interpolate.interpnd.LinearNDInterpolator._evaluate_double (scipy/interpolate/interpnd.c:3954)() /usr/lib64/python2.7/site-packages/scipy/interpolate/interpnd.so in scipy.interpolate.interpnd.LinearNDInterpolator._do_evaluate (scipy/interpolate/interpnd.c:4684)() AttributeError: 'Delaunay' object has no attribute 'simplices'
我之前从未见过这个错误,代码以前也有用过.在我不知道的scipy中,有些东西发生了变化吗？
谢谢你的期待！
解决方法
我想你使用的是旧版本的库：
Delaunay库有两个不同的simplices访问器：
“Delaunay.simplices”和“Delaunay.vertices”
这里显示(最新文档)：http://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.Delaunay.html
在两个Delaunay.vertices中标记为“已弃用”.
在Ubuntu 13.04上,simplices调用不存在,因为它仍然使用scipy 0.11.0：
http://docs.scipy.org/doc/scipy-0.11.0/reference/generated/scipy.spatial.Delaunay.html#scipy.spatial.Delaunay
尝试使用这个最小的例子或只是重写你的simplices调用顶点：
from __future__ import print_function
import numpy as np
from scipy.spatial import Delaunay
import sys
my_molecule = np.random.rand(400,3) #points for query
points = np.random.rand(1000,3) #points used for Triangulation
diag = Delaunay(points)
simplices = diag.find_simplex(my_molecule)
for point,simplex in zip(my_molecule,simplices):
if simplex == -1:
print ("Point not included in diag.")
continue
print ("Doing vertices call: ")
spoints = diag.vertices[simplex]
print ("Doing simplices call: ")
spoints = diag.simplices[simplex]
