我正在尝试使用IDLE以交互方式控制Paraview。这将涉及从IDLE发送命令并查看Paraview中发生的更改。我宁愿不使用in-Paraview python shell。
到目前为止,我已成功从IDLE导入Paraview模块(简单,servermanager等)。但是,发送的命令不会反映在Paraview中。例如:
>>> from paraview.simple import *
>>> cone = Cone()
>>> Show()
>>> Render()
确实创造了一个圆锥体。但是,锥体输出到新的独立OpenGL窗口,而不是Paraview GUI。
是否可以使用IDLE以交互方式控制Paraview?如果是这样,怎么做到这一点?感谢

您需要在多客户端/服务器模式下运行paraview。 在终端运行pvserver。
./bin/pvserver --multi-clients
在另一个终端中,运行paraview并连接到您的服务器
./bin/paraview
File->Connect
AddServer -> Choose a name -> Configure -> Save
Connect
在第三个终端中,运行pvpython(或您自己配置的python)
./bin/pvpython
>> from paraview.simple import *
>> Connect("localhost")
>> Cone()
>> Show()

我针对系统python构建了paraview,以便可以使用ipython
和其他软件包。我只需要将PYTHONPATH
设置为指向paraview python网站包,然后将LD_LIBRARY_PATH
设置为指向paraview lib目录。
export PYTHONPATH=/path/to/paraview/install/lib/python2.7/site-packages
export LD_LIBRARY_PATH=/path/to/paraview/install/lib
$ ipython

我的paraview版本是由master在Ubuntu 18.04上构建的。
我唯一遇到的问题是python site-__init__.py
目录中缺少packages/paraview/modules
文件。
In [1]: from paraview.simple import *
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)

我通过在__init__.py
目录中创建一个paraview/modules
文件来解决此问题:
touch /path/to/paraview/install/lib/python2.7/site-packages/paraview/modules/__init__.py
