    <title>Mathematica won’t install on Trixie 64bit</title>
    <link>https://community.wolfram.com/groups/-/m/t/3558367</link>
    <description>Hello  &#xD;
I tried using the shell script from wolfram website to install 14.2 on Trixie  &#xD;
Didn’t work due to failed dependencies…  &#xD;
So I downloaded these two pkgs manually from ftp.debian.org  &#xD;
libprec3_8.39-13_arm64.deb;   &#xD;
libwayland-egl1-mesa-22.3.6-1+deb12u1_arm64.deb  &#xD;
And after installing them, I can proceed with the installation…  &#xD;
Any suggestions if there is a better way?</description>

    <title>Cloud chat notebooks frequently entirely failing to produce output?</title>
    <link>https://community.wolfram.com/groups/-/m/t/3488555</link>
    <description>This must be a bug of some kind. &#xD;
&#xD;
It&amp;#039;s not even consistent, but when it&amp;#039;s occurring, no matter what input I give a cloud chat notebook cell, using Wolfram as the LLM service, OpenAI as the LLM service, or even Gemini as the LLM service, there will be long periods when the evaluation of the chat notebook cell either returns an errored-out empty cell, or it briefly displays an empty cell and then deletes that in-progress empty output. If you mouse over the red cell (when it does show up), you see an error: &amp;#034;An unknown box name (ToBoxes) was sent as the BoxForm for the expression. Check the format rules for the expression.&amp;#034;.&#xD;
&#xD;
Here&amp;#039;s an example where I evaluated a blank chat notebook input, with just that red inner cell showing up:&#xD;
&#xD;
![empty cell with ToBoxes error][1]&#xD;
&#xD;
The TLDR is that there might be an errant backtick after `UpdateInterval` breaking everything somehow:&#xD;
&#xD;
    Cell[&#xD;
      BoxData[&#xD;
        DynamicBox[&#xD;

        ]&#xD;
      ],&#xD;
&#xD;
Can you spot it?&#xD;
&#xD;
&#xD;
----------&#xD;
&#xD;
Ok, now what made this extremely difficult is that I believe somehow the parsing diagnostic reports an issue with the `form` argument to `ToBoxes`, even though it looks like it&amp;#039;s correct (`StandardForm`). Indeed, tweaking and playing around with it gives a clue:&#xD;
&#xD;
    ToBoxes[&#xD;
        Refresh[&#xD;
            CompoundExpression[Null]`&#xD;
            ], StandardForm&#xD;
        ] &#xD;
&#xD;
yields:&#xD;
&#xD;
    Syntax::sntxf: &amp;#034;Refresh[&amp;#034; cannot be followed by &amp;#034;CompoundExpression[Null]`]&amp;#034;. &#xD;
&#xD;
&#xD;
Removing the errant backtick gives a result that&amp;#039;s almost reasonably renderable.&#xD;
&#xD;
Now here&amp;#039;s where things get a tiny bit deep. Because the issue is sometimes invisible, I had to start off my debugging session by tracking down the code that draws the tooltip. I was curious, so I spent several hours digging into the cloud chat notebook javascript implementation - thankfully I&amp;#039;m familiar with react and modern react buildsystems. &#xD;
&#xD;
If you ever need to debug the wolfram cloud notebook interface, this information may be useful. They&amp;#039;ve not obfuscated the code, so if you&amp;#039;re running in `PRD` instead of `LOCAL`, `LOCAL8080`, or `DEVEL`, the logging functions are there, just nopped out. To turn it all on, look for the debug logger class, you can search for `debug()` in `dist/dyn/layoutWithNotebook.modern[some hash string].modern.js` and you&amp;#039;ll see where the shims are nopped out:&#xD;
&#xD;
                    warn() {}&#xD;
                    info() {}&#xD;
                    debug() {}&#xD;
                    trace() {&#xD;
                        this.enabled &amp;amp;&amp;amp; f &amp;gt;= _(&amp;#034;trace&amp;#034;) &amp;amp;&amp;amp; console.trace()&#xD;
                    }&#xD;
&#xD;
Then, if you set a breakpoint either after the class is finished defining, or at debug `itself` (will fire on any invocation of debug), you can monkey patch them back into functionality quite easily with the console as such: &#xD;
&#xD;
    (this.__proto__.warn = console.warn) | (this.__proto__.info = console.info) | (this.__proto__.debug = console.debug) | (this.__proto__.trace = console.trace)&#xD;
&#xD;
If you do this you will quickly end up with thousands and thousands of log entries - they were quite thorough when building a full clone of the Mathematica environment in the browser. You&amp;#039;ll probably enjoy chrome devtools crashing frequently from the memory usage.&#xD;
&#xD;
This logging indicated there are a surprising number of unimplemented functions being sent to the browser client to evaluate, including symbols that look like they might be important to the functionality I&amp;#039;m using (e.g. `Unsupported symbol Wolfram`Chatbook`UI`MakeChatCloudDockedCellContents`). I can&amp;#039;t tell if I&amp;#039;m just experiencing two separate issues (blank output due to models spitting out unsupported symbols, separate from the backtick issue?) or something deeper.&#xD;
&#xD;
Given I don&amp;#039;t have access to mathematica desktop these days, I&amp;#039;ve been playing around with the cloud notebooks instead, so I&amp;#039;ll have to fuss with this more.&#xD;
&#xD;
&#xD;
For completeness, here&amp;#039;s the notebook:&#xD;

    <title>Accessing Wolfram products on Pi 4 if user ne PI</title>
    <link>https://community.wolfram.com/groups/-/m/t/1931746</link>
    <description>One of the first things I did with my brand new Pi 4 was to create a new user id for myself, and disable the login for PI.  One of the second things I did was to try Mathematica (interesting, that is a spelling error here) and Wolfram and the Intro workbook &amp;#034;FirstCourseOnRPI.nb&amp;#034;. The third thing I tried to do was run any of it, and I had absolutely no luck; I was consistently asked for a Key that I didn&amp;#039;t have, and (in spite of several requests to Wolfram and this forum) was unable to obtain. &#xD;
&#xD;
The problem was found in an old post here, which said membership in the group &amp;#034;video&amp;#034; was required. It didn&amp;#039;t solve the problem at first, but after a PI reboot, all was well again.  I (think, be careful, from memory) what I  did was:&#xD;
sudo chuser -a -G video myuserid (the capital G is important, to add(-a) a non-primary group (-G) membership for the user specified); &#xD;
groups  (to list memberships, find yourself and check video has been added)&#xD;
sudo reboot  (careful if on a vnc connection.)&#xD;
The default user Pi probably wont have any of this grief, but at least change the default password!</description>

    <title>How to make Manipulate / Dynamic work in JupyterLab</title>
    <link>https://community.wolfram.com/groups/-/m/t/1887748</link>
    <description>Hello, I am a data scientist in Amazon, due to some security and customer privacy reasons, we are not allowed to playing data on local machine, all the data must be stored in S3 bucket for security, and the only interface we can use to access the data is Amazon SageMaker notebooks.&#xD;
&#xD;
I have always been a huge fan of Dynamic and Manipulate functionality for almost 10 years, and would like to keep using Wolfram Language in industry data science, where Python is the only language people use now. And I was happy to see that WolframEngine is finally free for developers, which made it possible to convince my co-workers to try.&#xD;
&#xD;
However, I found the JupyterLab does not support Manipulate and Dynamic functionality, is there any Jupyter front end extension can solve my problem? Right now it&amp;#039;s just impossible to display anything normally.&#xD;

    <title>After installing Mathematica, troubles with forked processes</title>
    <link>https://community.wolfram.com/groups/-/m/t/1823777</link>
    <description>I installed Mathematica (12.0.0) in my HPC environment, and after getting an X-Windows server going on my laptop, was able to run it and just did some rudimentary things. This was run on one of the login nodes - the wrong place for it in production, I know, but I was just testing. Eventually I decided to exit and work out making sure regular user access to the program environment would work. But some sort of error came up. The popup that had the message was garbled, so I couldn&amp;#039;t read it. But I also couldn&amp;#039;t close the window or its ancestors. I eventually exited from my Linux session (CentOS 6.x), and even that didn&amp;#039;t seem to kill it. I had to go back to my desktop and exit from X to close these windows and (I thought) exit from Mathematica.&#xD;
&#xD;
Since then, I went to log in again and got the following:&#xD;
    -bash: fork: retry: Resource temporarily unavailable&#xD;
    -bash: fork: retry: Resource temporarily unavailable&#xD;
    -bash: fork: retry: Resource temporarily unavailable&#xD;
    -bash: fork: retry: Resource temporarily unavailable&#xD;
    -bash: fork: Resource temporarily unavailable&#xD;
I didn&amp;#039;t realize it, but Mathematica was still running. When I finally figured that much out, I killed the individual Mathematica processes that were running, and was able to reconnect to the server and login normally.&#xD;
&#xD;
The question really is, has anybody experienced this sort of thing? If so, how did you resolve it? I obviously can&amp;#039;t turn this over to the user community with this sort of defect or I will spend the rest of my days killing mathematica. &#xD;
&#xD;
I will eventually need to get into recommended ways to configure X and Mathematica. But for now, I just need to be able to keep this problem from coming up. Any help?</description>

    <description>I wrote some code reading data fast from a TCP device. It worked reliably under Mathematica 10.3.1 on Raspberry Pi 3B+ and 10.4 on Windows 7, but no longer under versions 11 or 12 on either platform. On my Windows PC I kept 10.4, as fall-back. But how can I downgrade on the Raspberry Pi?  &#xD;
&#xD;
    sudo apt-get install wolfram-engine&#xD;
&#xD;
installs version 12.0.1 and &#xD;
&#xD;
    apt-cache madison wolfram-engine&#xD;
&#xD;
only shows that version as candidate.&#xD;
&#xD;

    <title>Use machine learning modules without enabling my discrete Nvidia GPU?</title>
    <link>https://community.wolfram.com/groups/-/m/t/1604185</link>
    <description>I cannot use some of the machine learning modules without enabling my discrete Nvidia GPU.&#xD;
&#xD;
My setup:&#xD;
&#xD;
 - Ubuntu 16.04 on a Dell XPS-15 9560 Intel i7 CPU with 8-cores,&#xD;
 - Integrated IntelHD Graphics 630 (Kaby Lake GT2) card &#xD;
 - Discrete Nvidia GTX-1050 card&#xD;
&#xD;
To save power and reduce noise, I disable the discrete graphics card (using the Nvidia prime-select tool) .&#xD;
In this mode, running NetTrain leads to the error:&#xD;
&#xD;
LibraryFunction::libload: The function WL_MXGetVersion was not loaded from the file /usr/local/Wolfram/Mathematica/11.3/SystemFiles/Components/MXNetLink/LibraryResources/Linux-x86-64/MXNetLink.so.&#xD;
&#xD;
Re-enabling the Nvidia graphics card and rebooting fixes this problem. However, the default mode of NetTrain is to run with &amp;#039;TargetDevice -&amp;gt; &amp;#034;CPU&amp;#034; &amp;#039; so surely I should not need to enable my Nvidia card to get this to work.</description>
