Hi, I'm new to Python programming in Maya, actually really new, in other words I won't be as active for a while.  In the meantime I was hoping someone can help me with a script to iron out a problem ?

Hi

Welcome to the group!

We have plenty of members here that are just getting started. Feel free to ask questions. Just do your best to ask focused questions with examples of what you tried and what you expected, and you should be able to receive focused answers. And put long code samples in a pastebin link (or avoid long code samples)

If it's getting started with Python in general, it will also help to go through some basic tutorials first before asking the group about fundamental python.

Enjoy!

Thanks, I appreciate it.

For now, I have a script I would love if someone on this list could help me with.  The script works, but there is a little issue that plaques me, I'm not the author of the script, and I've tried to get help from the author without much success.

Post the script on a pastebin. Copy what you did and the errors your are getting. Can't help until we see something.

The script is available online "UV Deluxe", or do you prefer I post the code as well ?

Clicking any one of the tabs within the tool causes this error;

box is false
# Error: 13
# Traceback (most recent call last):
#   File "<custom path>\UVDeluxe\uvdeluxe.py", line 230, in <lambda>
#     ec=lambda *args:uis.setUiState())

#     UiStates.pickleDump(self)
#   File "<custom path>\UVDeluxe\uistates.py", line 36, in pickleDump
#     datafile = open(UiStates.path+UiStates.filename,'w')
# IOError: [Errno 13] Permission denied: 'C:/config.uvd' #

Crest, I would love nothing more than to help you solve this problem, but you're not making it very easy.

If you have a look at some of the other questions in this list, or on StackOverflow, you'll find that the best thing for you to do would be for you to share an isolated snippet of code with the problem. That way, I could more easily determine what may be causing this issue.

Also, for the best possible answers, I would strongly suggest skimming this.

Presumably the tool is trying to write out a data file to your C: drive, and does not have permission.
Without the link to the source, I can't be sure, but is there an input for telling it where to store this file? Apparently your C: root is not a sufficient location.

Reading my reply again, I find that it probably came off a little blunt. Sorry about that, Crest.

Apology accepted.  :-)

What I originally meant was, if you download the script, the problem comes when using it, there is no problem trying to get it to work or anything of that nature.  The problem is strictly once ran and clicking one of the menus I get the error mentioned in my previous message in the script error, and it is that error I hope I can eliminate so the script runs clean. 

There is no script for me to post in pastebin, although if no one wants to download the script on their own, I will post the individual code files for analyzing if needed ?

Thanks again everyone !

Ok, nobody here wants to be a jerk, but I think it needs to be said, so...

Christopher, you're not really using this list for it's intended purpose. While most people here are happy to help if someone shows at least an interest in learning scripting / programming, you really haven't demonstrated any desire to do so.

Instead, what you've done is post a very vague "plea for help" with somebody else's script.  I doubt anybody on this list signed up because they wanted to offer general help-desk service for anybody with a problem in Maya - or anybody with a problem running a script in Maya.

While people will step in and help with these sort of pleas for help from time to time - because most people are nice, and like to help - if this list starts accumulating too many of these requests, folks will start ignoring it and stop using it.  Which would be a shame.

In other words - please don't post to this list unless you're genuinely looking to learn python scripting. Thanks!

Hello Christopher,

try replacing C: (__file__.split('\\')[0]) for you user's home path,
maybe that way you can check if the problem is with writing permissions.
where it says (uistates.py line 9)

class UiStates():
        filename = 'config.uvd'
        path = __file__.split('\\')[0]+'/'

change it to:

class UiStates():
        filename = 'config.uvd'
        #path = __file__.split('\\')[0]+'/'
        path = os.environ['HOMEDRIVE']+os.environ['HOMEPATH'].replace('\\','/')+'/'

Cheers,
Eduardo

Ugh, don’t do manual path concatenation! :)

import os
path = os.path.join(os.environ['HOMEDRIVE'], os.environ['HOMEPATH'])

Better yet, use expanduser

import os
path = os.path.expanduser("~")

That way it isn’t dependent on Windows.

Well it's a windows thing, try to create a new file on your c: drive root, and probably you'l get
a prompt asking for a user or a password, or simply you will get a denial.
if this is the case, it's because your account doesn't have enough privileges to write there.
maybe if you created a folder (like 'C:/temp/'), you can create files in there.
Cheers,
Eduardo

Hey Christopher,
Marcus is right  ;)
Anyway ,i don't know how the script handles de paths later,
and if it doesn't work with the \\ path
try something like this
path = os.path.expanduser("~")
path = path.replace('\\','/')+'/'
and it will be left just like he original version uses it.
Something about the  __file__.split('\\')[0]+'/' tells me it not a platform independent script...
Cheers,
Eduardo
