Unable to install the v.0.4.7a thonny-py5mode plug-in on Windows.

[villares]

This is disturbing, I think I need help. I have tried a clean install of Thonny 4.1.7. portable on Windows 10 Pro (I also checked for stuff at /AppData/Local/Programs/ and /AppData/Roaming/Thonny).

After installing the thonny-py5mode plugin version 0.4.7a (which installs py5 0.10.7a0) Thonny won't launch anymore (silently crashing on launch).

I'm guessing some of our dependencies updates or something on py5 0.10.7a0 is causing this problem, because my older zipped portable (available at https://github.com/villares/thonny-portable-with-py5/releases/download/2025-06-11/thonny-417-with-py5-0106a0-portable-r3.zip) still works.

I can also report that installing just py5 0.10.7a0 works, and when you install the plug-in, Thonny stops launching.

Can you try this with an older version of Thonny?

In another thread @GoToLoop said that there are a lot of places where the plugin overrides or monkey patches Thonny's code. It is possible that Thonny has changed in a way that is no longer compatible with the plugin. Perhaps? This is my first guess.

In any case, this is a problem and in particular we need to make sure we have a reliable way to do installs before the tutorial at Python Brasil.

[villares]

I will try. But my working portable is using the same Thonny 4.1.7 version...

In any case, this is a problem and in particular we need to make sure we have a reliable way to do installs before the tutorial at Python Brasil.

The portable with py5 0.10.6a0 still works on every machine I tested. I tried to upgrade py5 on the portable on this computer where I am right now (a different one from the reported issue) and was able to bring it to 0.10.7a0 (using the Thonny system shell feature, the GUI panel failed). I'll try moving this portable to another computer to see how it goes.

[GoToLoop]

I've already reported that problem here:
#77 (reply in thread)

On Windows 10 using latest Thonny 4.1.7 installer, seems like upgrading from thonny-py5mode plugin 0.4.7a to 0.5.0rc5 fails if we don't clean up subfolder %AppData%\Thonny\plugins\Python310\site-packages 1st!

But this was me trying to install 0.4.7a on 4.1.7... so before any 0.5.0 modification.

Also there are two kinds of Windows 10 at the community center: desktops and laptops. It looks like on the desktop things work and on the laptop they fail.

I'll double check the subfolder thing (I'm pretty sure I have removed all remnants of earlier installs).

I had to leave, I'll try to investigate further tomorrow.

[villares]

So. I tried a bit more and I couldn't gather any more useful information 😢

Installing on older Thonny failed, I tried 4.1.4 and couldn't install the plug-in from GUI panel (possibly because of the PyPI search issue fixed on 4.1.7) and installing rc5 local file also failed (I think it also tried to find dependencies online and failed).

After many fruitless attempts, I'm giving up looking into this for now. I wonder if @aivarannamaa would have some insight on this issue.

My conclusions:

I couldn't discern the difference between the two types of Windows 10 Pro computers at the community center with the two different behaviours:

• Thonny 4.17, with plug-in v0.4.7a and py5 v0.10.7a
  • classroom latptops - crashing on Thonny launch (older portable with py5 v0.10.6a still works).
  • office desktops - working

I think it is some interaction of newer py5 v0.10.7a with the plug-in (either 0.4.7 or rc5) under certain conditions (?) I can't understand or reproduce. I swear I deleted all older AppData stuff.

@hx2A, for our tutorial we have some options, I suppose:

• Use the slightly older Thonny 4.1.7 portable with py5 0.10.6a and plug-in pre-installed.
• Use Thonny 4.1.7 with py5 0.10.7a, install a JDK (possibly with install-jdk) and use it without the plug-in.
• We could use conda and Jupyter Notebooks.

[hx2A]

I just tried Portable Thonny on my Windows 11 computer and it worked fine. I was able to install the latest plugin from pypi and everything ran correctly.

Is this just a Windows 10 thing? What kind of updates has Windows 10 been getting these days? I read that all Windows 10 support ends on the 14th. That's a problem for people who still need to use it. As time goes on, newer software will require resources from the computer that Windows 10 machines can't provide. More things will break.

The "Windows fatal exception: access violation" error I believe is like a segmentation fault in Linux. It seems more likely to be a DLL version issue than a problem with Python code.

I can also report that installing just py5 0.10.7a0 works

Can you install just py5 0.10.7a0 and run a Sketch? The access violation error you got suggests it failed when importing jpype. Can you just import jpype and start the JVM?

Thonny won't launch anymore (silently crashing on launch).

When Thonny launches, does it import py5 anywhere? If so, why? It really ought to run a Sketch by spawning a new process.

[hx2A]

It really ought to run a Sketch by spawning a new process.

I just tested this by running a Sketch that calls jpype.shutdownJVM(). If each Sketch was run in the same process as the editor, this command would prevent any future Sketch from running. That's not the case, thankfully.

[villares]

Can you install just py5 0.10.7a0 and run a Sketch? The access violation error you got suggests it failed when importing jpype. Can you just import jpype and start the JVM?

Yes I can run a module mode sketch, py5 0.10.7 works perfectly without the plug-in. The access violation only happens during the plug-in loading, which crashes Thonny on launch. So, py5 0.10.6a + plugin works, py5 0.10.7 + plugin doesn't.

This problem only exists on Windows 10, right?

[hx2A]

@hx2A, for our tutorial we have some options, I suppose:

* Use the slightly older Thonny 4.1.7 portable with py5 0.10.6a and plug-in pre-installed.

* Use Thonny 4.1.7 with py5 0.10.7a, install a JDK (possibly with `install-jdk`) and use it _without the plug-in_.

* We could use conda and Jupyter Notebooks.

Since this is an intermediate tutorial, we can assume that people are savvy enough to have Python already installed, right? Given the content I think that Jupyter Notebooks are the best format for me to use because I can include images and extensive written explanations for stuff.

BTW I have been working on preparing for the presentation and tutorials. For the tutorials I have worked out 2 out of 3 of the code examples I'll be working through. The first is Shapely only, the second is Trimesh only, and the third will build on top of the first two and tie things together in a way that should feel constructive. I know time is running short but I hope to have at least a rough draft ready by next weekend that I'll share with you.

@villares When you test "py5 0.10.6a + plugin" what version of jpype is installed? If it is 1.5.2, can you come up with a way to test "py5 0.10.7 + plugin" and force it to downgrade jpype from 1.6.0 (now min default version for latest version of py5) to the previous version 1.5.2?

I'll see what I can do, I'll try it.

I'm not 100% sure of that :(

Ugh. :(

But I think we'd have a lot more people reporting problems if it was on Windows 11 also.

If it is 1.5.2, can you come up with a way to test "py5 0.10.7 + plugin" and force it to downgrade jpype from 1.6.0 (now min default version for latest version of py5) to the previous version 1.5.2?

BINGO!

@hx2A, I managed to install the Thonny plug-in and before relaunching Thonny I downgraded jpype to 1.5.2 and it all worked.

So it is something to do with jpype1 1.6.0. Progress.
