Plotter closes automatically about pyvista-support

[laserman781]

It seems to work fine this way

[rgangrade]

I was experiencing the same issue. Tried researching a bit and used %matplotlib qt before the scene. Works fine for me. I am quite new to Python so this may not be a great solution, but it works fine!

[GuillaumeFavelier]

I'll close this since it has been taken care of by pyvista/pyvista#502

The fix is now available in the version 0.23.0 of pyvista !

Can you provide code to reproduce this?

This is the code producing the error:
I tired restarting the kernal and the same thing happens every time...

@interact_calc(holes='Enter file path', blocks='Enter file path')
def selection(holes, blocks):
    with out:
        clear_output()
        if blocks != 'Enter file path':
            grid = pv.read(blocks+'.vtk')
        H = pv.read(holes+'.vtk')
        h = widgets.SelectMultiple(options=DH['Name'],description='Drillholes',disabled=False)
        print('Specific Query')
    @interact_calc(select=dh,regex='Enter selection')
    def plot(select,regex):
        with out:
            clear_output()
            if regex != 'Enter selection':
                extracted = query(H,'Name',regex)
            else:
                extracted = query(H,'Name',select)
            print(extracted)
        @interact_calc(savename = 'Enter extracted drillholes name')
        def plot(savename):
            with out:
                clear_output()
                extracted.save(savename+'.vtk')
                print('saved')
                p = pv.Plotter() 
                surface = extracted.extract_surface()  # Extract the outer surface
                cells = surface.cell_centers()   # Grabb the cell centers
                p.add_mesh(extracted, show_edges=True)
                p.add_point_labels(cells, cells.active_scalar_name)
                p.remove_scalar_bar()
                if blocks != 'Enter file path':
                    p.add_mesh(grid)
                p.show()

I have a feeling this has to do with the fact that you have two plot functions in your namespace... try renaming the second one.

[laserman781]

So I fixed this, and still the same issue...

[banesullivan]

I cannot reproduce anything from what you shared... can you provide a simplified, reproducible example?

Also, maybe screen captures of what you're experiencing? And a more detailed explanation of this phenomena...

[laserman781]

Here is a more simplified code where I receive the same issue...
I have attached a screen capture of the issue I am seeing. (I just realized)

import pyvista as pv
DH = pv.read('sample_drillholes.vtk')
p = pv.Plotter(notebook = False)
p.add_mesh(DH, show_edges=True)
p.remove_scalar_bar()
p.show()

[laserman781]

I just realized my gif didn't come out right...

[banesullivan]

Huh that’s very strange. Can you share a report from that same notebook:

import pyvista as pv
print(pv.Report())

[banesullivan]

And you noticed this only after upgrading to version 0.22.0?

[laserman781]

This was never an issue until just recently...

[banesullivan]

Would you please also run the same code from a Python interpreter on the command line to see if it happens there too?

_{Sent with GitHawk}

[banesullivan]

That's good to hear it is at least working from the command line.

I'll investigate a bit further to see if I can reproduce this - currently I have no idea why you are experiencing this issue in Jupyter notebooks.

In that same notebook where the issue appears, could you print the following:

import pyvista as pv
print('OFF_SCREEN: ', pv.OFF_SCREEN)

[laserman781]

I receive this:
OFF_SCREEN: False

I've tried creating new notebooks, reinstalling PyVista and I get the same issue every time

[banesullivan]

very, very strange. Try this snippet as well just in case...

import pyvista as pv
DH = pv.read('sample_drillholes.vtk')
p = pv.Plotter(notebook=False, off_screen=False)
p.add_mesh(DH, show_edges=True)
p.remove_scalar_bar()
p.show()

[banesullivan]

And then try this.... with the auto_close flag

import pyvista as pv
DH = pv.read('sample_drillholes.vtk')
p = pv.Plotter(notebook=False, off_screen=False)
p.add_mesh(DH, show_edges=True)
p.remove_scalar_bar()
p.show(auto_close=False)

[laserman781]

In the first one, the same things happen. The second one works fine, although if I run the first one, and then run the second one after it crashes and the kernel dies.

[banesullivan]

@laserman781, are you still experiencing this issue?

[banesullivan]

Thanks, @rgangrade! That's a weird fix, so I'll have to take a look at what's going on there
