我正在尝试学习如何从命令行运行VisIt，并且我已经能够使用visit -cli和提供 Python 命令（即 ieOpenDatabase("somefile.vtk")等）来制作绘图。

除了ipython口译员之外，还有其他方法可以做同样的事情吗？

我试过了

import visit
visit.OpenDatabase("somefile.vtk")

这给了我错误'module' object has no attribute 'OpenDatabase'

另一方面，如果我跑

import visit
visit.Launch()
visit.OpenDatabase("somefile.vtk")
...

VisIt GUI 已打开，之后的所有内容都visit.Launch()将被忽略。

我不确定你们是否知道这一点，但我不确定这是否可能，除非你从头开始构建访问。如果您下载他们的二进制文件，它会安装自己的 python，并重置您的 PYTHONPATH，并添加某些库。查看他们的启动脚本（bin/visit），应该可以构建 VisIt 以使用系统 python，此时您可能会鼓励它使用系统 ipython。但这将在 VisIt 配置时完成，而不是在运行时完成。

也就是说，如果您确实找到了破解方法，请发布答案，因为我也想知道！

在 OSX 上运行它更难，因为你必须用自己的 python 手动修复硬编码的 python 路径，比如 anaconda 2。

VisIt 是使用 Python 2 构建的，因此导入不适用于 python 3。

这是一个 OSX 脚本：

OSX 导入配置

否则，根据 VisitManual 在 Windows 中，您可以简单地附加您的访问安装路径并导入访问并使用如下脚本启动它：

import sys
import os

sys.path.append("C:/Program Files/LLNL/VisIt 2.12.2/lib/site-packages")

winSavePath = os.getenv('USERPROFILE')

import visit
visit.Launch()

import visit_utils as vu

所有后续调用均visit.OpenDatabase()作为示例

有一个 Linux 版本的 Visit，也许可以针对 OSX 进行修改。
