TypeError:ufunc'add'不包含循环

问题描述

我使用Anaconda和gdsCAD并在正确安装所有软件包时收到错误消息.就像这里解释的那样: http://pythonhosted.org/gdsCAD/

I use Anaconda and gdsCAD and get an error when all packages are installed correctly.Like explained here: http://pythonhosted.org/gdsCAD/

TypeError: ufunc 'add' did not contain a loop with signature matching types dtype('S32') dtype('S32') dtype('S32')

我的导入看起来像这样(最后我导入了所有内容):

My imports look like this (In the end I imported everything):

import numpy as np
from gdsCAD import *
import matplotlib.pyplot as plt

我的示例代码如下:

something = core.Elements()
box=shapes.Box( (5,5),(1,5),0.5)
core.default_layer = 1
core.default_colors = 2
something.add(box)
something.show()

我的错误消息如下:

推荐答案

从图形化安装到此绘图问题，gdsCAD一直很痛苦.
此问题是由于将错误的数据类型传递给colors函数.可以通过在core.py

The gdsCAD has been a pain from shapely install to this plotting issue.
This issue is because of wrong datatype being passed to colors function. It can be solved by editing the following line in core.py

colors += matplotlib.cm.gist_ncar(np.linspace(0.98, 0, 15))

到

colors += list(matplotlib.cm.gist_ncar(np.linspace(0.98, 0, 15)))

如果您不知道core.py的位置.只需输入:

If you dont know where the core.py is located. Just type in:

from gdsCAD import *
core

这将为您提供core.py文件的路径.祝你好运！

This will give you the path of core.py file. Good luck !
