General question about scripts, some scripts tell you to place them in your python directory, whether that is your Maya default installation directory or a custom directory set forth by your maya env variable file.  At the moment my scripts are all throw in a custom python scripts folder, quite messy, I have begun placing the scripts within the python scripts folder, but within a respectful directory for organization, and also for easy upgrading of scripts, maybe some of you do this as well ? 

Since beginning to do this, I get when running the script command, whatever that may be for a particular script; I get the following error;  <script name> is not defined error ?

They don't have to specifically be placed in Maya's python locations. They just need to be in the PYTHONPATH by some means. Like you said, this may have been extended via the Maya.env or otherwise.

Is this the actual python error? What were you trying to execute, and where was it located on your file system?

This is the actual error, although the script is not called <script name> you knew that, that is strictly a placeholder for the actual script name. I placed the script in my pythonscripts path and I get that error, does it matter if the script is within a folder in the pythonscripts path ?

Again... what exactly were you trying to execute?
Where does this script live on the filesystem?

If you are seeing that error, then something is incorrect in your configured PYTHONPATH. If you are placing scripts into sub-directories of your target PYTHONPATH location, make sure you are including empty __init__.py files in each one. These are required in order to indicate to the python import mechanism that it should traverse into these directories to treat them as packages.

I imagine you are trying to call the script name and not importing it first.

Justin is asking you to post exactly what are you are trying to do, what code you are trying to execute. Please don't make people on this list try to guess what you are doing with hypothetical questions. This disrespects the time and knowledge of the people you are calling on.

Don't say "when running the script command". Paste exactly what you are trying to execute.

I know there isn't a good error message, but out of;
Cannot find procedure or Name Error file <maya console> line 1 is not defined are they both one in the same with regards to error messages.  The script is a python script, when placed in the custom scripts folder, I get the first error; when placed in the pythonscript folder, I get the second error.  The difference, one contains MEL scripts, typically, the other Python. And if the script doesn't have a import command ?




I've placed other Python scripts in the path which is in my environment variable, and the scripts worked, if the script doesn't require

I don't really know how to respond to this, to be honest. If your script is in your PYTHONPATH, then you should be able to import it. If you haven't imported it, then you can't access it. If you can't import it, then you have something wrong in either your environment, or you put it in a sub-directory that doesnt have an __init__.py

Python scripts should not go in your mel script path.

Hi,

If ever it can help you. It's not a cleaned script but it works

I create this tool for laod all my scripts when maya loading. 
It's possible to reload all your scripts

for exemple with your tool in D:\work\Maya_Tools
--------------------------------------------------
sys.path.insert(0, r'D:\Work')
from Maya_Tools.divers_tools.plugin_manager import Plugin_Manager

Maya_Tools = r'D:\work'

Plugin_Manager.window_close_all_pyside() # Only work with QMainWindow
Plugin_Manager.modules_delete(['Maya_Tools'], ['plugin_manager', 'AssetImporter'])
Plugin_Manager.modules_load([Maya_Tools, ])
--------------------------------------------------

Do not forget the __init__.py file in your Scripts folder : D:\work\Maya_Tools\__init__.py
if you don't have this file in your directory Python will fail to load the scripts

As the saying everyone if no mistake in the path there should not be any problem in your script loads.

It allows reloader scripts by destroying the modules and reloading them.
Shortly be with this solution you can fix your problem

Justin the __init__.py file should be in the location of the rest of the python scripts for the script package so if I have the script in a folder along with the __init__.py file, Maya Environment variable can traverse though the directories \ folders, correct ?

I can't understand, I have other python scripts that are located in the same custom environment pythonscripts folder, and they work, although there not in sub-folders, rather thrown together, if that makes a difference ? 

When I try to execute; for example the script that I'm currently struggling with to work in which I placed in the same custom pythonscripts folder as the other pythonscripts; the only difference is this particular python script is in it's own sub-folder within the pythonscript folder I get the typical cannot find procedure error ?

Let's say you add this to your PYTHONPATH:

   /my/custom/path

This location can have scripts directly inside of it, such as:

   /my/custom/path
      foo.py

... Which would then let you do "import foo" in Maya.

You could also have packages, by doing:

   /my/custom/path
      package1/
         __init__.py


         foo.py

...  Which would then let you do any of the following :

import package1
import package1.foo
from package1 import foo


I can't understand, I have other python scripts that are located in the same custom environment pythonscripts folder, and they work, although there not in sub-folders, rather thrown together, if that makes a difference ? 


It doesn't matter if you have random scripts mixed together in one directory. If you have subdirectories in there, they need to have an __init__.py as well

When I try to execute; for example the script that I'm currently struggling with to work in which I placed in the same custom pythonscripts folder as the other pythonscripts; the only difference is this particular python script is in it's own sub-folder within the pythonscript folder I get the typical cannot find procedure error ?

Are you using a Python tab in the script editor? Sounds like a Mel error.

If you follow my previous suggestions, you should not have a problem. If you do have a problem still, what exactly are you trying to execute in the python tab?

X:\...\...\pythonscripts\

That is the path I have in my Maya Environment file, in that path I have for example a script

X:\...\...\pythonscripts\SuperScript\

In that sub-folder called SuperScript I have the __init__.py file when I go to execute the command that needs to be executed for the script, correction from previous, I get the error SuperScript is not defined ?

tl;dnr this whole thread.  But you'd need to:

import SuperScript.myModule
SuperScript.myModule.myFunc()

That's executing the myFunc function in the my myModule.py module living under /SuperScript dir.
x:/../../pythonscripts/SuperScript/myModule.py

Generally, I don't often put any code in the __init__.py  (I do occasionally for very specific reasons).  In general they're just there to get your package paths setup right, so you can import everything correctly without any fuss.

No. "Superscript" is the name of the package (directory). Then you have some module which is the name of your file. So if you file is called myFile.py, then you do

import Superscript.myFile
Superscript.myFile.ui()

I wonder the same thing, myself, with multiple threads of unsolvable problems.

Trying my best to help, as long as the responses are clear and show effort or progress. But my interest is diminishing.

I feel a good book on python programming or a tutorial on basic Mel could solve these initial problems. But it seems no upfront studying is being done.
