#54943 — Neurolab // "No module named .."

Hiya
A word of warning, I am a complete beginner.
My problem goes like this:: I've been trying to "import neurolab as nl"(a neural network library)and I keep getting the "No module named.." error in my Python 2.7.3 shell. There is definitely something wrong with my Python path, although everything looks fine (to me). I also appended the sys.path with "C:/Python27/neurolab-0.2.3/neurolab" and I still get that error. What am I missing?
Thanks.

How exactly did you install python?  And how did you install neurolab?
Also, its best to actually cut and paste the traceback rather than
paraphrase it.  Since you don't know what is wrong, you may not be
providing the information necessary to solve the problem

Welcome to the forum, and to Python.

First point:  when you have a problem, especially an import problem, in
some (unnamed) shell, make sure the same symptoms happen at a command
line or the Python interpreter, whichever is appropriate. If the
problem only occurs in the shell, it's a shell problem, or probably a
configuration one.

Second point:  Include the source file you use, hopefully stripped to
the essential minimum.

Third point: include a transcript of all, or the significant portions of
the session (using cut and paste, not paraphrasing). The error
(exception) message is a minimum of 3 lines long,  You show part of the
last line.  The full error message starts with "Traceback" and ends with
some textual summary error message.

Fourth:  indicate how you may have customized your system.  At a
minimum, you must think you installed the neurolab module.  Whatever
that is, whereever you found it.  You should supply the link.

But perhaps you downloaded it and copied it, without actually running
any install program. The directory you specify is NOT the conventional
place for foreign modules.

For example:

davea@think2:~/temppython$ python
Python 2.7.3 (default, Apr 10 2013, 06:20:15) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import unknown
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named unknown
>>>

Perhaps that sys.path should contain directory paths but not module 
paths. I suspect that "C:/Python27/neurolab-0.2.3" is the directory you 
should append. Import will then find the neurolab module it contains.

Are you sure that path is correct?  I'd expect to see something like 
"C:/Python27/lib/site-packages/neurolab-0.2.3/neurolab"

That's very true. If it's meant to be in the Python folder, then I'd
expected it to be in the "Lib\site-packages" subfolder.

	Welcome...

	... but why is a "complete beginner" trying to work with such an
advanced third-party library before first learning the core language and
libraries.

>looks fine (to me). I also appended the sys.path with "C:/Python27/neurolab-0.2.3/neurolab" and I still get that error. What am I missing?

	A compliant third-party library commonly /would/ have installed its
importable parts in "c:\python<vn>\Lib\site-packages\<package>" -- or where
ever Python was installed: C:\Python_x64\Python27\Lib\site-packages\MySQLdb
for example on my system for the MySQLdb package.

	It wouldn't need modification of the search path.
