[Paraview] BUG?: Paraview 3.14.1 Linux 64-bit --> can not call GradientsOfUnstructuredDataSet through python script

[Janusz Michalik]

Its really strange it took me several tries of doing the same thing to get the error. Just to make sure its not any typo, I used python trace to get the script I attached to this e-mail (test.py). As I understand it should run no problem in the python shell. I highlight the data set (STSone) in the pipeline and ran the script and still get


Traceback (most recent call last):

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

TypeError: 'GradientOfUnstructuredDataSet' object is not callable



On a side note I'm getting this:

QPainter::begin: Paint device returned engine == 0, type: 2

QPainter::setRenderHint: Painter must be active to set rendering hints

QPainter::setBrush: Painter not active

QPainter::end: Painter not active, aborted

What is this error? It pops up periodically...

I'm able to get the GradientOfUnstructuredDataSet filter through the GUI's python interpretor so I'm not sure what's causing your problem. Could you share the script?

I am able to cause problems if I don't have an active filter/source when creating the GradientOfUnstructuredDataSet filter since it complains, as it should, that there isn't a proper input for it.

Sorry, in the e-mail I misspelled it. I do use:

GradientOfUnstructuredDataSet()

as the error indicates; it is not related to the spelling. After I sent out the first e-mail I tried Paraview 3.14.0 Linux 64-bit and it works, so for what I need this is fine. I think it is a bug that needs to be fixed in 3.14.1, if it hasn't already been fixed in the developers version.

GradientOfUnstructuredDataSet
GradientsOfUnstructuredDatSet()

There’s a spelling discrepancy between the two: missing “A” in data, and extra “S” after gradient. Could that be the issue?

Hi all,

I switched from Paraview 3.12.0 to 3.14.1 Linux 64-bit and have the following error:

Traceback (most recent call last):

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

TypeError: 'GradientOfUnstructuredDataSet' object is not callable


when I try to take the gradients of the velocity by calling: GradientsOfUnstructuredDatSet(). This worked in 3.12.0, did something change? Is there a quick fix for this? Please let me know. I would go back to the old version except that the numpy eig functions return 0+0i for any matrix I throw at it (so another bug which I assume won't be fixed since its an older version).

Best,
Janusz
