Question

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创建绘图并提供Python命令，即OpenDatabase("somefile.vtk")等

除了ipython解释器之外，还有相同的事情吗？

我试过

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")
...

打开VisIt GUI，忽略visit.Launch()之后的所有内容。

VisIt 2.6
IPython 0.13
Mac OSX 10.8.3

我不确定你们是否认识到这一点，但我不确定除非你从头开始访问，否则它是可能的。如果你下载他们的二进制文件，它会安装自己的python，并重置你的PYTHONPATH，并添加某些库。看看他们的启动脚本（bin / visit），应该可以构建VisIt以使用系统python，此时你可能会鼓励它使用系统ipython。但这可以在VisIt配置时完成，而不是在运行时完成。

那就是说，如果你确实想办法解决问题，请发一个答案，因为我也想知道！

Answer 2

在OSX上运行更难，因为你需要用自己的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，因此导入将无法与python 3一起使用。

这是一个OSX脚本：

OSX import configuration

否则，在Windows中，根据VisitManual，您只需添加访问安装路径并导入访问并使用以下脚本启动它：

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

所有后续通话都以visit.OpenDatabase()为例

有一个Linux版本的Visit，也许可以针对OSX进行修改。
