Unable to display an image

As the title suggests Everything is okay include display an equation, solve a differential equation. THE IMAGE JUST DONT SHOWN UP, even if there's no an error report

Which Wolfram Engine version, OS, VS Code version, and extension version are you using?

[Florianismeandonlyme]

Both my Mathematica and Wolfram Engine version is 12.3, the extension version is v0.06

P.S: Sometimes the wolfram engine would notice me to Launch a mathlink program and when I run the codes again, there would be a 'rending failed' error:

Which Wolfram Engine version, OS, VS Code version, and extension version are you using?

[njpipeorgan]

I was not able reproduce this problem with Engine 12.3. I suspect that the subkernel was not launched successfully.

You can try opening the output window (Ctrl+Shift+U) and select the Wolfram Language Notebook tab while connecting to the kernel, and see what the output is.

Same question here, I can generate 2D plots, but fail with 3D ones (generate a blank figure)

ContourPlot3D[
 x^3 + y^2 - z^2 == 0, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}]

Plot[Sin[x],{x,-1,1}]

[lyyc199586]

when changes to plain text, the output looks fine:

so I doubt this is something wrong with the notebook render for 3D plots.

[njpipeorgan]

Thanks for the feedback. I cannot reproduce this issue on Windows/Linux with Mathematica/Engine 13.0. As it was a blank image and Plot did work, I suspect that it may be a kernel-related problem. How about converting the graphics to an image manually, like Rasterize[ContourPlot3D[x^3 + y^2 - z^2 == 0, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}]] ?

Maybe you can try disabling all other extensions or reinstalling the kernel.

[lyyc199586]

Rasterize didn't help...

I am using wolframscirpt:

disabling all other exts doesn't help either

Are you using the kernel over WSL?

[lyyc199586]

Yes, WSL2 (ubuntu)

[njpipeorgan]

As far as I know, the kernel relies on X windows system to render some graphics, which can go wrong in WSL.

[lyyc199586]

This is a little bit frastrating..

There is a similar work on using Jupyter notebook as a frontend for mma in browser, WolframLanguageForJupyter. But this didn't work for vscode.

Anyway, I think your extension is so far the best solution to use mma notebook in vscode. bravo!

What is your platform?

[njpipeorgan]

VSCode has native support for Jupyter, so I assume WolframLanguageForJupyter as a Jupyter kernel can work in VSCode. But I'm not sure whether that will solve this problem.

Thanks.

I've been testing the extension on Windows, Ubuntu, and MacOS.

[lyyc199586]

WolframLanguageForJupyter didnt work in vscode, I have tried it when I found that repo... and there is an issue about that issue.

Only 3D plots don't work, that's very strange...

[njpipeorgan]

Thanks for the info. You can also test rasterizing 3D graphics in the kernel in WSL terminal directly, e.g.

img=ImageData[Rasterize[ContourPlot3D[x^3 + y^2 - z^2 == 0, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}]]];
Dimensions[img]
Mean[Mean[img]]

and see if it is normal.

[lyyc199586]

that looks fine

Out[2]= {549, 481, 3}

In[3]:= Mean[Mean[img]]

Out[3]= {1., 1., 1.}

In[4]:=  

[njpipeorgan]

It actually did not look fine. Note that the average of the image was {1.,1.,1.}, which means it was a blank image.

[lyyc199586]

yea... that's weird, let my check it in a jupyter noteboook in browser

[lyyc199586]

I think that bug only occur on WoframEngine 13.0, because I remember that I could generate 3d plots when I was using 12.3, (or they removed this feature in 13.)

🤣

[lyyc199586]

Finally I'm sure this is a bug only on WSL, I tried it on windows and it works fine.

[njpipeorgan]

Thanks for the information.
