No traitsui.toolkits plugin could be loaded for qt4

Haha, just had the same experience from a fresh pip3 install. For me this solved the issue: pip3 install pyqt5

I am not able to see output just white screen after the code

Is this resolved or is this still an issue?

Hi, I met the same error "RuntimeError: No traitsui.toolkits plugin could be loaded for qt4". I tried to pip install pyqt5, but it didn't work. Do you have any idea?

Can I ensure some questions? Did you use pyinstaller to pack the exe? when you packed it, was there some warnings like: "lib not found in folders like ‘pyqt’"？ I want to know if the error of "RuntimeError: No traitsui.toolkits plugin could be loaded for qt4" is related to the dependency of dll in pyqt folders.

Any resolution to the issue?

You need to install pyqt5 or pyside2 or pyside6; a compatible UI toolkit should resolve the issue. Otherwise dump VTK files using pysph dump_vtk and load it up with ParaView. Alternatively, use pysph binder and use the created notebook (this is quite limited but should let you at least view the data). This is really not a pysph issue per-se but more a Mayavi one so closing.
