#39228 — Python module import failed error

Hello all; I am using Ubuntu 12.10 and Python v2.7.3.  I am trying to add a directory to the PYTHONPATH.  All of the commands I have found on the web have failed.  Please help me to add a directory to the PYHONPATH.  The file path is Home/home/bin.  Thanks in advance.

What do you mean by that path? That doesn't look like an Ubuntu/Linux
path name. Pull up a terminal (Ctrl-Alt-T should do that for you,
though I haven't used an Ubuntu since 10.10) and see if you can 'ls'
the path - once you have the real path name (it might start with
/home/your_user_name/ for instance), go back to the commands you found
on the web and try them - they'll probably work, then.

thats the file path.  the directory "bin" in my home directory.  in bash it obviously looks like this  "~/bin" using the file system folder the path is home/Home/bin.  i have tried commands like, export PYTHONPATH=${PYTHONPATH}:/users/matt/bin or home/matt/bin or Home/home/bin and nothing has worked.
from what ive found on the web the Python import process is notoriously underspecified, notwithstanding i was under the impression that PYTHONPATH is a global variable that i can add directories to at anytime to tell Python where to look, without having to add some sort of code to every program.  is this impression incorrect?  is there some code i need to add to the Python program call the modules in the "bin" dir?

Change to that directory, then type 'pwd'. That'll tell you the actual
path. My guess would be /home/matt/bin - note the leading slash.

What exactly do you mean by "no luck"? More details would be good.

The program i am using (GNU radio companion) that wants to import the modules from the ~/bin folder shows this error:

Block - import_0_0_0 - Import(import):
  Param - Import(import):
    Import "import multimode_helper as mh" failed.

Hi,

Do you run Python in the same terminal than where you run the export
command ?

no i dont. the python program looking for the modules in the ~/bin directory is called GNU radio companion.

What is PYTHONPATH actually set to?  You can find out by running python 
interactively, then

import os
os.environ['PYTHONPATH']

By typing the simple command  'python'
    davea@think2:~$ python
Python 2.7.3 (default, Aug  1 2012, 05:14:39)

But since you're running some non-python program which is in turn 
launching python, perhaps you'd better give more details.  And not 
scattered over a half dozen tiny emails, but all at once.

Do you, in a single terminal, do the export, then run the 
gnuradiocompanion.py ?  And does the error message/stacktrace appear in 
the same terminal window?

Please show us just what you're running, from start to finish.  Thanks.

hi.  ok so i  am trying to run the python module (multimode_helper.py) in the GNU radio companion (GRC) which is sort of like an IDE which lets you organize code blocks by arranging them in a flow graph instead of having to write the code that would call the blocks in some particular order. GRC shows the import error in its flow graph error viewer:

Error 0:
Block - import_0_0_0 - Import(import):
  Param - Import(import):
    Import "import multimode_helper as mh" failed.

The directory /home/matt/bin contains "multimode_helper.py" and this file path is in the PYTHONPATH.  I still get the import error however. so now that i know the file path is in PYTHONPATH but i am still getting the import error i am really confused here.

Thanks for your attention.

Do you understand how Unix environment variables work? You're using
the 'export' command, but that doesn't make any sort of global change
- it still applies only to things done in the same session. (Actually,
your change applies only to children of the shell where you do it...
but never mind that now.) You may do better by putting the export
command into your .bashrc - that would apply to all sessions created
by your user.

	And that already looks like a mess...

	Do you actually have separate directories named

		/home

and
		/Home

(Linux/UNIX is case sensitive)


	And do you really have your account split between

		/home/matt

and

		/users/matt
