Usage example not working

[danieljuschus]

The usage example is not currently working for me. No errors, but the 3D model is not shown.

There is also a deprecation warning: PyVistaDeprecationWarning: pythreejs backend is deprecated and is planned for future removal.

The examples on the page on the Streamlit Community Cloud don't work either anymore: https://stpyvista.streamlit.app/,

Windows 10, Python 3.11, pyvista 0.38.5, stpyvista 0.0.5, streamlit 1.20.0

Indeed, pyvista's pythreejs backend is getting deprecated in favor of trame . I was moving to the panel backend, which is arguably better than pythreejs, but that one is also deprecated now so never merged that branch. :/

[edsaac]

Sorry, didn't mean to close the issue. I'll try to port stpyvista to trame eventually in a next version. For now, fixing pyvista to a previous version (maybe 0.36.0) should do the trick, but cannot confirm that yet.

I cannot find any combination fixing the pyvista version to something older that fixes the issue. Could someone do it ?

if so could I get the version of all packages ?

Also, the trame is interesting when do plan to have this included ? Do you need help somehow ?

[edsaac]

I tried many version combinations and could not figure out the problem. My guess now is that something is broken in the threejs library and I gave up. So I released version 0.0.6 of stpyvista to just use the panel backend, which --although deprecate-- still works!

You can upgrade to version 0.0.6 via pip (pip install stpyvista -U). Tests seem to be passing in st.pyvista.streamlit.app but lmk if something else broke.

[anciaux]

Thanks you so much. It indeed worked!

Not working for me unfortunately, I keep getting errors like

File "C:\Users\jusc_da\Documents\AirFuCS\airfucs-calc\venv\Lib\site-packages\panel\io\save.py", line 295, in save
    with io.open(filename, mode="w", encoding="utf-8") as f:
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
PermissionError: [Errno 13] Permission denied: 'C:\\Users\\______\\AppData\\Local\\Temp\\tmpz13yuo84.html'

[edsaac]

That looks like a permissions configuration issue with your computer, when panel attempts to create temporal files.

Hello, I have the same problem, how did you solve it?: PermissionError: [Errno 13] Permission denied:.

Thanks you

I have not yet found a solution. Unfortunately I am currently restricted to a Windows machine without admin rights. Are you in the same situation perhaps?

[edsaac]

That might be fixed using a io.BytesIO object instead of a tempfile for storing the exported panel view. I'll update when I modify that in stpyvista.

I think that this problem results from accessing temp file in "root/stpyvista/panel/io/save.py", line 295 when NamedTemporaryFile in "root/stpyvista/__init__.py", line 84 hold the temp file.
To handle this problem, I changed "root/stpyvista/__init__.py", line 83 ~ 86

        # Create HTML file
        with NamedTemporaryFile(mode='a+', suffix='.html') as model_html:
            geo_pan_pv.save(model_html.name, resources=INLINE)
            panel_html = model_html.read()

To

        # Create HTML file
        temp_path = ""
        with NamedTemporaryFile(mode='a+', suffix='.html') as model_html:
            temp_path = model_html.name
        geo_pan_pv.save(temp_path, resources=INLINE)
        with open(temp_path, 'r', encoding="utf-8") as model_html:
            panel_html = model_html.read()

This code just get temp file name from NamedTemporaryFile and release that temp file.
Then it process next things.

I got rid of the whole temporary file in version 0.0.7 of stpyvista. Test seem to be passing at https://stpyvista.streamlit.app/, so you should be good after upgrading (pip install stpyvista -U). But again, lmk if something failed!

[jaedong27]

I checked working about version 0.0.7. Thank you!
(Window 10, python 3.8.0)

[danieljuschus]

Works for me too, thanks! Shall we open a new issue for trame?

[edsaac]

Sounds good 👍

[danieljuschus]

Is it just me or is the translation of the view using the middle mouse button not working anymore with the panel backend?

[edsaac]

Shift + click does the panning.
