Python Fipy Grid3D'；索引只能有一个省略号'；错误

我对用fipy解微分方程很感兴趣

当我使用Grid2D时，以下代码工作正常

从fipy导入*
网格=网格2D（nx=3，ny=3）
#网格=网格3D（nx=3，ny=3，nz=3）
phi=CellVariable（名称='solution variable'，网格=mesh，值=0。）
φ约束（0，网格面宽）
φ约束（10，网格面右侧）
系数=单元变量（网格=网格，值=1。）
等式=扩散项（系数）=0
方程求解（var=phi）

当我使用Grid3D而不是Grid2D（注释行）时，出现以下错误：

我使用来自的«推荐方法»安装了fipy。我尝试在pthon3.6和python2.7中使用Miniconda进行安装，但得到了相同的错误

如何使用Grid3D解方程？

这是因为较新版本的numpy对我们草率的语法容忍度较低。您可以签出我们的或修改您的代码。

尝试使用，例如，重新运行。该错误可能已修复。对于FiPy的特定版本，我可以同时使用Grid2D和Grid3D。
