Add support for Maya 2022 with Python 3.7

[1fth3n3ls3]

When I try to execute Send Python Code to Maya I get this error.

`

Yeah, this would be a much needed update for me, thanks!

[artbycrunk]

Thanks for reporting, let me have a look and get back

[Rourker]

Thanks a lot

Apologies this is taking a while, just got my hands on a copy of 2022.
WIll have a fix out soon.

[artbycrunk]

ok so one quick solution is to avoid using the -echoOutput when you init the commandPort

so instead of this

commandPort -name "localhost:7001" -sourceType "mel" -echoOutput;

you can run just this

commandPort -name "localhost:7001" -sourceType "mel"

Note that you need to do this in a new maya session, as you cannot modify the ports you have already opened.

There is a bug in this file, that is causing the issue with echo output.
C:\Program Files\Autodesk\Maya2022\Python37\lib\socketserver.py", line 799

@artbycrunk I think there is another improvement to make.
execfile() is replaced by exec() in python 3,and it's still execfile() being used in MayaCode extension.

[ypypjay]

Sorry that I can't make a pull request because I'm still newbie in programming and afraid to mess your code up.

[ZachGray]

Love this extension, would love an update to execfile() for 3.7/2022 if it's simple enough.

[CraigMason]

Just to confirm, this does not work with a fresh install of Maya 2022 with the same error described above:

# Error: line 1: NameError: file <maya console> line 1: name 'execfile' is not defined #

[Ruka1998]

Just to confirm, this does not work with a fresh install of Maya 2022 with the same error described above:

# Error: line 1: NameError: file <maya console> line 1: name 'execfile' is not defined #

@CraigMason
You can try this one https://github.com/DubiousLatchkey/vscode-maya/tree/2022-3.7-support
Pack the source code to vsix installer and reinstall will fix this issue.

[Leo-Vitalis]

Just to confirm, this does not work with a fresh install of Maya 2022 with the same error described above:

# Error: line 1: NameError: file <maya console> line 1: name 'execfile' is not defined #

You can change the execfile line to:

cmd = python("exec(open('${posixPath}').read())");

extension.js file should be located at C:\Users\name\.vscode\extensions\saviof.mayacode-1.4.0\out
There is a copy of the file in src folder, I changed the line in both.

Hello,
I'm dying over here being forced to use multiple overcomplicated IDE's.

Can @artbycrunk b a hero do all this in the main branch and ad a toggle option to the config?
I'm also not versed with pull requests etc.

EDIT: thx 4 the quick reponse

[artbycrunk]

Apologies this took a while to get to,

Please update to the latest version of extension 1.5.0

Note that there is a new setting required to be enabled when using Maya 2022.

[artbycrunk]

@NicTanghe @Vitali-Iakovlev @Ruka1998 @CraigMason @ZachGray @ypypjay @a690089735 @Rourker @1fth3n3ls3
hope its working for everyone now.

[ZachGray]

Thanks for the update!

Works great the first time, but sending subsequent snippets seems to break the port. (using 7010 because of a port conflict)
Maya 2022.1 x64
Let me know if I can provide better info or help debug. Using in conjunction with the MayaPy extension which has a dependency on MayaCode

Sorry about that, missed the post about
commandPort -name "localhost:7001" -sourceType "mel"

Note that you need to do this in a new maya session, as you cannot modify the ports you have already opened.

There is a bug in this file, that is causing the issue with echo output.
C:\Program Files\Autodesk\Maya2022\Python37\lib\socketserver.py", line 799

This is the same error at the top of the thread. Curious why it might be changing after first execution.

# ----------------------------------------
# #   File "C:\Program Files\Autodesk\Maya2022\Python37\lib\socketserver.py", line 799, in write
    self._sock.sendall(b)
# TypeError: a bytes-like object is required, not 'str'
# ----------------------------------------

[artbycrunk]

@ZachGray I am not able to reproduce this,
all I can think of is that one of your snippets is using commandPort with -echoOutput
that should be the only reason to get a traceback with socketserver.py", line 799

[Fadeevone]

Hi guys, for everyone who still have issues with socketserver and other stuff from this thread,
first - check that you had fixed this line commandPort -name "localhost:7001" -sourceType "mel";
second - reinstall this plugin, and also reinstall MayaPy plugin if you have, because they have some dependencies. I don't know why, but it works for me.

Thanks everyone, btw

Hi I have seen this post in the autodesk site that talks about this issue in particular.

It seems like from Python2.7 to 3.7 maya expects a command to be passed as a bytes instead of strings. The link includes possible solutions so feel free to give it a look :)

[kristafervale]

+1 what @mrbmp33 said

Not to double post but here's what I found debugging this issue in Maya 2023:

I have an update on what I found after doing a little digging around in Maya's source scripts.

in the file
F:\Program Files\Autodesk\Maya2023\Python\Lib\site-packages\maya\app\general\CommandPort.py

On line 134, as an experiment I changed it

from:
self.wfile.write(self.server.commandMessageQueue.get() + self.resp_term)

to:

self.server.commandMessageQueue.get() + self.resp_term
#self.wfile.write()

effectively telling it to go ahead and execute the message in the commandMessageQueue but don't do the self.wfile.write().

And wouldn't you know it, after reloading Maya everything worked as expected.

print("hello world")
outputted to the output just fine,

and
cmds.sphere(r=1,n="hell_world_sphere")
created a nurbs sphere called hello_world_spehre as expected.

I'm not sure what you will have to do to update your extension, obviously we can't all edit our Maya source code to make this work, but hopefully this will lead you in the right direction?

[wesschneider]

@kristafervale Thanks for your input... you save the day :)

[AgastyaPatel]

Ref:
Check this for solving. This solved the issue for me

import maya.cmds as cmds
cmds.commandPort(name="127.0.0.1:7002", stp="python")
cmds.commandPort(name="127.0.0.1:7001", stp="mel")`

To debug Above Maya 2022 Python code in VS Code, you can use the "Debugger for Maya" extension available here:
