On some occasions I have seen output like this

where the user name is replaced by a placeholder.
How to achieve this?

Hi,

I was just wondering if there is a init file for the Windows version of Maple, like there is one for the LInux version.

I'm not talking about the Maple.ini file located in the user's Application Data folder. In the Linux version, there is a file, .mapleinit, where you can place all of your initialization setups, like the packages you want to automatically load with the worksheet, defining constants, etc.

If someone has any ideas, I really appreciate it. Thanks very much in advance.

I`m trying execute the example of Deeplearnig:

with(DeepLearning);
v1 := Vector(8, i -> i, datatype = float[8]);
v2 := Vector(8, [-1.0, 1.0, 5.0, 11.0, 19.0, 29.0, 41.0, 55.0], datatype = float[8]);
model := Sequential([DenseLayer(1, inputshape = [1])]);
model := Vector(2, {(1) = Typesetting:-mi("`DeepLearning 

   Model`"), (2) = Typesetting:-mi("`<keras.engine.sequential.Se\

  quential object at 0x000001C5B6520700>`")})

model:-Compile(optimizer = "sgd", loss = "mean_squared_error");
model:-Fit(v1, v2, epochs = 500);
"<Python object: <keras.callbacks.History object at 0x000001C5CC\

  EE9DE0>>"

convert("<Python object: <keras.callbacks.History object at 0x000001C5CCEE9DE0>>", 'symbol');
<Python object: <keras.callbacks.History object at 0x000001C5CCE\

  E9DE0>>

model:-Predict([10]);

But, finally, there is this error:

Error, (in Predict) AttributeError: 'CatchOutErr' object has no attribute 'flush'

['Traceback (most recent call last):\n', '  File "C:\\Program Files\\Maple 2023\\Python.X86_64_WINDOWS\\lib\\site-packages\\keras\\utils\\traceback_utils.py", line 70, in error_handler\n    raise e.with_traceback(filtered_tb) from None\n', '  File "C:\\Program Files\\Maple 2023\\Python.X86_64_WINDOWS\\lib\\site-packages\\keras\\utils\\io_utils.py", line 80, in print_msg\n    sys.stdout.flush()\n', "AttributeError: 'CatchOutErr' object has no attribute 'flush'\n"]

What`s is happening?

Thanks!

Here's a few commands you can use within Maple to collect information about your computer.  This is on a Windows 7 machine but should work for most Win7+ systems.  Not sure how far back the WMIC commands can be used, and it won't work on Mac or Linux. 

Download Maple_-_computer-info.mw

Maple (2023.1) opens regularly but I cannot use "open" or "save" or "save as" and after opening Maple I no longer can close it.

That is a big problem for me.

The issue is on my new laptop Lenovo L13 Yoga with Windows 11.

Any suggestion? Thanks

I made the upgrade to Maple 2023 today and for fun I compiled a simple procedure. I got an error in Maple 2023. So I ran the same lines of code in Maple 2022 and eveything works. Does anyone sees this problem?

I need your help....

Here is a demonstration involving two decision problems (where evalf is applied to the output for better readability): 
 

Download SMTLIB[Satisfy].mw

As you can see, the SMTLIB:-Satisfy command fails to work in Maple 2023, and I have to install the Visual Studio 2013 (VC++ 12.0) manually. But unfortunately, even if I have installed the vcredist_x64.exe beforehand, the computation still cannot be done in 1000 seconds! (Please note that I just require one real instance rather than all solutions.) Does anyone know why? 
By the way, since the default SMT solver (in Maple 2023) is Z3, will another SMT solver (like cvc5) be supported in future Maple releases?

I know that this is not really a question regarding core Maple package, but I am running into problems during the installation process.

After having upgraded Maple networktools as mentioned, I am unable to run the activation program due to an error.

"Java Virtual Machine Launcher: Error: Could not create the Java Virtual Machine."

I've never had that problem before in previous versions. There was no Java installed on the (virtual) server, so I installed the latest OpenJDK to check if that solved the problem.

Unfortunately it didn't.

Any hints would be appreciated.

Windows Server 2012R2

My Maple Program run perfectly  with Window 10.  My new Laptop has Window 11 and I get system  crash wenn I applied

plot3d(...) .

So I think It is somethink with the Grapics Redering ?

Can somebody help ?

I use Maple 2020 on a Windows 10 PC.

The command ssystem("CMD") enables to launch any Windows command accessible from the shell.
But how to launch a PowerShell command?

For instance ssystem("get-process") returns -1 (not surprising in fact for get-process is not a shell process).
How can I tell Maple that this command is to be found in the PowerShell ?

And even, I this possible for, in the ssystem help page, it's said that not all the command can be launched by ssystem

TIA

Any idea why I can't write Excel output to my standard Documents directory?

Writeout to a different directory outside seems to work.

Any specific Windows rights that need to be given to a directory for writeout?

windows 11 maple 2020 I can load other packages but cannot load the student packages

I am trying to compute the determinant of a 3 x 3 matrix. It has very involved symbolic entries.

The cpu goes to 100% and after about a minute I get BSOD on windows 10. Using a 4 core i7 64 gig of ram.

Can I stop Maple using all the cores to see if this helps the BSOD.?

A few days ago my Windows 10 (32 bit) operating system did an update of my Excel 2016. Since that moment I get following message:

However the addin toolbar is still present and WMIMPLEX.xla file is also still present. Removing and reinstalling the addin did not help. So I am wondering what other solutions could be done.

Aside of this I would like to ask some help for the correct syntax in Thermodynamics package calculating water vapor pressure. For one or another reason I do not succeed to find the correct syntax to obtain the water vapor pressure at 24°C.

Thank you in advance for any help
