Hi ParaView Team,
when using ParaView-5.13.3-osmesa-MPI-Linux-Python3.10-x86\_64/bin/pvpython
and importing
from scipy.spatial.transform import Rotation as R
I get follwing ValueError:
numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject
It seems scipy is not compatible with `Numpy >= 2`
Best regards,
Jan

`from scipy.spatial.transform import Rotation as R`
This import works fine in ParaView nightly binary release on Linux.
Can you try it: [https://www.paraview.org/download/?version=nightly](https://www.paraview.org/download/?version=nightly)

Just tested, I confirm it works with the Full suite
ParaView-5.13.20250429-MPI-Linux-Python3.12-x86\_64/bin/pvpython
however unfortunately not with the headless version
ParaView-5.13.3-2-g22fe491f25-osmesa-MPI-Linux-Python3.10-x86\_64/bin/pvpython

This is the headless version of the release branch.
There is no headless version anymore for the master branch nor for the upcoming ParaView 6.0
In any case, that means this issue has been fixed.

ok, thanks for clarifying. Besides, I get another error related to the OpenFOAMReader:
```auto
from paraview.simple import *
foam=OpenFOAMReader(FileName='tmp.foam')
Traceback (most recent call last):

```
Or shall I open anther task for this?

Im unable to reproduce, it works fine with my OpenFOAM data.

I am getting this only with the nightly binary. I cannot even start the GUI with that version. Starting paraview result in:
```auto
ParaView-5.13.20250429-MPI-Linux-Python3.12-x86_64/bin/paraview-real: symbol lookup error: /usr/lib/x86_64-linux-gnu/libQt6DBus.so.6: undefined symbol: _ZN9QtPrivate23CompatPropertySafePointC1EP14QBindingStatusP20QUntypedPropertyData, version Qt_6

You should clean your env variables, right now you are using your system Qt because LD\_LIBRARY\_PATH is set.

you are right, after cleaning the environment the nightly binary runs fine, both GUI and pvpython. Thanks for your support!
