[Paraview] [paraview] out of memory

[dxy]

Utkarsh,
Thank you very much for your help! I tried as you said, but still the error. Did i lack of some settings?



Traceback (most recent call last):

File "<string>", line 19, in <module>

File "<string>", line 6, in RequestData

NameError: global name 'vtkPLYReader' is not defined

Thanks,
dxy
