I created a python code that creates a legacy VTK file, but paraview is failing to read it, even thou it’s, as far as I can tell, following the proper formatting.

Paraview version I’m using is 5.13.2

Only thing I’m not sure is correct is using “float” instead of “double”, since what python calls a float is a double on other systems, but I testes changing them and still got the exact same errors.

Start of the file is as follows:

# vtk DataFile Version 2.0

DATASET STRUCTURED\_POINTS  
DIMENSIONS 128 128 127

-0.0 0.0 0.0  
(Rest of the data)

And the errors I get are:

Generic Warning: In vtkDataReader.cxx, line 1526  
Error reading ascii data. Possible mismatch of datasize with declaration.

ERROR: In vtkDataReader.cxx, line 1024  
vtkStructuredPointsReader (00000263DC0E6DA0): Unsupported point attribute type: -0.0 for file: C:\Users\Usuario\Documents\Pedro\Faculdade\Estagio\_2023\Resultado\Teste.vtk

Any idea what could be causing it? Thank you for your help
