I'm at a complete loss; I have downloaded a script and, it's late so I won't go into every last step I've tried.  What is the problem, I continue to get "no module found".  I have a maya environment file, all the paths are setup correctly, I added a module path hoping it would work, no success.  Are other scripts working, more or less yes, the odd one gives me problems, what that odd one is, is completely random.  I hope someone can help.

Hey Christopher, 

I would be happy to help, but honestly there isn't a lot to go on here. All I can tell you without seeing some more information, is to check your PYTHONPATH again, and make sure you don't have a module name conflicts (where it is picking up a similarly named files).

Can you point us at the script, and let us know where you have placed it on your filesystem, and what your PYTHONPATH looks like, and how you import it?

Justin

Hi Justin, I've checked everything a dozen times, what you mean by module name conflict, how do I check this ?
 

Can you point us at the script, and let us know where you have placed it on your filesystem, and what your PYTHONPATH looks like, and how you import it?


One of the scripts, I have an issue with two and I hope I can with whomever help finally resolve, it was working, I got a nasty malware attack, now it doesn't work, I've been over this issue elsewhere and I kinda feel embarrassed because I thought I had this resolved and it doesn't work again, sorta makes me look like an idiot.  I decided well might as well look like an idiot on the Maya Python group, and face the music. 

 
The first script is NSUV (Nightshade UV Editor), I've kept things clean I have a sub-folder located within a folder,the Maya.env file points to that folder which is exclusively the PYTHONPATH folder, the same goes for SCRIPTS, ICONS etc. I import the script by the following command

import NSUV
reload (NSUV)

I hope after looking like an idiot that is, with some help, I'll be able to solve this once and for all.

Justin

I just grabbed a copy of that Nightshade plugin and tried it. Worked right away. Are you sure you followed the instructions? I just copied over the contents of the bundled "scripts" directory to my Maya's scripts location. I happened to put it in the shared scripts location, on my mac:
$ ls -1 /Users/justin/Library/Preferences/Autodesk/maya/scripts 
NSUV 
calcUVStats.py 
texturePanel_NSUV.mel
texturePanel_NSUV_2015.mel 
textureWindowCreateToolBar_NSUV.mel 
textureWindowCreateToolBar_NSUV_2014.mel 
textureWindowCreateToolBar_NSUV_2015.mel
​

The NSUV package gets picked up because the shared scripts location is on the default Maya pythonpath

Maybe post what your installation location looks like? I haven't tried to customize my Maya.env to point specifically to this or anything. More information would be helpful.

That is exactly how I have it laid out in my Maya.env file.  All script get placed in the scripts folder, all python scripts, get placed in the python folder.  In this case NSUV gets placed in the scripts folder, I have tested it in the python scripts folder as well with no positive results.

That is where I think your problem is. If you have made a custom script location, and set that as your maya script path, and placed a python package in there, then it won't work. Maya by default has the default script locations also on the PYTHONPATH. But in your custom Maya script location, I doubt it too is on the PYTHONPATH. Can you do the following from the Script Editor

import sys
for p in sys.path:
    print p

And confirm that you see the location where your NSUV python package exists?

Not sure how to solve your problem at this point then. Seems you have a ghost in the machine.
Did you try removing the custom Maya env and trying a standard install to a scripts location?

When I remove the Maya.env file, surprisingly a new Maya.env is created, now that is not the surprise, the surprise is, it loads a five month old Maya.env file, not a blank environment file, when I run the same command as mentioned;

import NSUV
reload(NSUV)

I continue to get this error; # Error: line 1: ImportError: file <maya console> line 1: No module named NSUV #.

I suspect this is rehashing something stupidly obvious, but are you able to just create your own generic python module (e.g. a dir within your scripts area with an __init__.py placeholder) and import it? I.e. is it a problem importing NSUV, or does the issue extend to something generic?

I probably should use the correct terminology - package, not module, a module being just a python file with statements in it, and a package being a way of structuring them in a file hierarchy to give you namespaces of a sort (Justin, feel free to correct me since I'm being very handwavey here). In short, it lets you use a dot notation to import packages that are split up down a filesystem tree, amongst other things.
 
 
 
By way of example, on my filesystem here, i've just created the following tree:
 
d:\devzone\scratchpad\working\foo
d:\devzone\scratchpad\working\foo\bar.py
d:\devzone\scratchpad\working.\foo\__init__.py
d:\devzone\scratchpad\working\foo\bacon
d:\devzone\scratchpad\working\foo\bacon\__init__.py
d:\devzone\scratchpad\working\food\bacon\sandwich.py
 
and then the following should work:
 
import sys
sys.path.append(r'd:\devzone\scratchpad\working')
# append the root of my package structure
 
import foo
import foo.bar
import foo.bacon
import foo.bacon.sandwich
 
For your problem, assuming that the root path of NSUV is visible Johan Bogström earlier suggested checking that you've an __init__.py and it's not missing - this is just the same check in a fashion, but even more brutal.
 
Also, as a side check - is everything cased correctly? I recall tearing my hair out once until i noticed i had two copies of a file, one with an uppercase first letter..

What I posted wasn't going to necessarily help you directly, it was more a debugging step to work out what's wrong and/or nail down a bit further any issues. If you can't import a python pack you've created yourself, then there is indeed a bigger issue with your setup than NSUV.

At this stage it's about stripping things back to the bare metal to work out what's gone wrong, and my gut feel is that there's something squiffy about your maya pathing, so that's sort of why I wanted to see if you can get a generic package of your own creation working.

I agree. I think this is just a pathing issue.

@Crest, run this bit of code from maya and tell me if you find NSUV. Feel free to paste back the results:
import os
import sys

for path in sys.path:
    test_path = os.path.join(path, "NSUV")
    if os.path.exists(test_path):
        print "NSUV found: %s" % test_path
    else:
        print "No NSUV found at %s" % path

Note: this code roughly represents what python does under the hood when you use "import whateva". The sys.path is just a list of paths to search. Components of PYTHONPATH are injected when python is first initialized.

Cheers,
Jesse

The result is; No NSUV in any of the paths when I run the script. ;-(

Why is it, when I've placed other python scripts or MEL scripts in paths that I set in the Maya.env file, those scripts work, but NSUV and ngSkinTools which does a really wierd behavior, when I click on the ngSkinTools icon in my custom shelf, first, you think the program runs, wrong, a loft icon shows up on a new shelf by its self, then I have to click the loft icon in the newly created custom shelf, then and only then does ngSkinTools runs, strange.

>From the looks of it the setup is wrong, I've read over setting up the Maya environment file dozens of times in the documentation that I swear I can't read it anymore, it's nearly memorized and yet I'm encountering this problem, I don't even want to attempt begining to start with python until this is resolved, that and I have projects to finish, anoth er reason why I haven't upgraded to 2016 because of this issue, all I ask is to solve it.

Well I don't think NSUV is doing stuff that is all that funky, because in my vanilla Maya 2015 setup, I simply drop it into the Maya shared "scripts" directory, and it works straight away. And that is because the "scripts" directory is *also* added to the PYTHONPATH. 

Did you happen to try the other recommendations, to place even a basic "hello world" test script in your desired location and confirm that you can import it? I think we have established that the funky thing here is not NSUV, but probably your specific configuration. It may be best to step away from a custom Maya.env and confirm that you are able to import basic python modules or packages in the default Maya locations. Then you can update the PYTHONPATH in your Maya.env and try placing stuff in there. If you are using a custom PYTHONPATH, then I *think* (can't confirm) that you would have to separate the NSUV directory into the PYTHONPATH location, and the mel scripts in the maya scripts path location.

I found that modules are a great way to keep things separated and organized AND working with very little overhead...
Did you try this approach?

Can I suggest you may want to send the entire output of Jesse's command? What it'll do is report back every path that the python interpreter will search. If it's not in that list, it's not being searched, so you can then work out from there.

Basically: what's the actual path you want to see, and what's the list of paths you're seeing?

That means the location you have placed your NSUV directory is not a location that is on the PYTHONPATH, thus will not be found when you try and import it.

The PYTHONPATH exists in the Maya.env file that is pointing to x:\6 on a drive. And it is that folder in which NSUV folder exists, although Maya is not seeing it ?

Interesting..
 
What's the path where you've put NSUV?
 
I notice there's no user directory there, but you do have something that approximates the structure in "C:/Custom Program Settings/Maya_Resources/Preferences/scripts"
 
Just checking, that looks awfully like a placeholder path? Or did you actually mean to have a number of directories under the literal "c:/Custom Program Settings/" root?

The absolute path, which is only a place holder due to this issue is X:\6 that is set in the Maya.env file and that is also the same location where the NSUV folder is located. 

Settings/Maya_Resources/Preferences/scripts"

That path is set in my system environment variable for the default path for Maya.

As Damon and Anthony have pointed out, there is a distinct lack of a folder like "Users/Documents/maya". This makes me believe that you are not operating in a "vanilla" windows environment. Someone else has their hand in your cookie jar.

Just go ahead and run:
import sys
sys.path.append("X:/6")
import NSUV

At some point you should talk to whomever else might be touching your configurations.

I have this system variable set, which defines my personal Maya application directory, from there my Maya.env file is read and that is where I set my environment variables for my paths, it's all in the documentation.

MAYA_APP_DIR
This variable defines your personal Maya application directory. This directory contains your projects and other important items:
the prefs directory
the projects directory
mayaRenderLog.txt
mayaLog
mayaJournal
the scripts directory
Maya.env, if you choose to create it, can also reside in this directory
You can only set MAYA_APP_DIR from the operating system; you cannot use Maya.env. If you set this variable in the Mac OS X operating system, you must launch Maya from the Terminal window. Otherwise, Maya will not use the set value.

I've run this command import sys
for pythonPath in sys.path:
    print pythonPath

I have 42 python paths, this may be the problem, how do I know what python path to place python scripts; since obviously the Maya.env file is not being read where the python scripts are placed ? I don't understand why I'm having this many problems for something that is relatively easy, I really must say at this point WTF.

I don't understand why you are having these troubles either, otherwise we might have pinpointed it long ago.

If you see your Maya.env defined PYTHONPATH in that list of 42 paths, then it means your Maya.env is being read and you can put your NSUV directory there.
If you do not see that custom path, then your Maya.env is not being read. And the correct place to put the NSUV would be any of the locations that are under the prefs or shared location (and not a system location or Maya internal application location )

Maya automatically gives you a number of locations on the PYTHONPATH. The results of "sys.path" is a combination of the custom env paths + Maya's internal paths + potentially system locations

There's an environment config that results in the paths as per the last dump - however it's gotten into this state isn't material though, this is just a list of paths for the python interpreter to search.
 
When you run an import statement, your interpreter will roll through those paths in order (first in the list, to the last) to find something that is importable. It's either going to be a bare python file, or a directory which houses an __init__.py file. For argument's sake, I'm just going to make reference to foo.py which is a file literally called 'foo.py' and contains a single newline. 
 
Based on that, looking at your last sys.path dump, assuming you want to import foo in terms of priority the last place to be searched will be C:/Custom Program Settings/Maya_Resources/Preferences/scripts and you should put foo.py there. Theoretically, you could also shove foo.py in C:\Custom Program Settings\Maya_Resources\pythonscripts as well.  (These appear to be paths you've set explicitly via PYTHONPATH in maya.env, and implicitly via MAYA_APP_DIR in your windows environment config by the way)
 
If setting up a foo.py thing as described above works, then theoretically, NSUV should also work. If it doesn't, then well, what imports for custom packages you've installed work and where do they come from? For example, if you do an import os, and then say, print os it should tell you that it's a module loaded from C:\Program Files\Autodesk\Maya2013\bin\python26.zip\os.py 
 
It's not a *clean* way to do things, but you could theoretically slam foo.py into one of those directories where you've got a working module, just to see what the heck is going on.

foo is just a placeholder, just like you'll see reference made in python docs to 'spam', 'eggs', (and possibly 'lumberjack') as placeholders for things.
 
If you're asking in terms of what foo.py is in the example? It's a file you make, that is literally called foo.py, and contains a single newline, so you can 'import foo' and see if you get errors.

Right, so it means you can import a custom module from an arbitrary path on your system, so if you unpack NSUV into wherever you put foo.py, you should be able to import NSUV.
