[Py2exe-users] Importing a package not included in library.zip

[Jason Raff <jraff@ce...>]

Hi All,

I also posted a similar question to the python usenet group, but I so
far haven't gotten any response.  I've just had no luck finding as
answer to this, but it seems like this would be something done fairly
commonly.

Using python 2.4, I've created a testing application.  When the app
starts up, I do a "from tests import *" and it looks at the /tests
directory and loads up all the tests it finds at that time.  This works
fine when interpreting the python code directly.  The problem I'm having
is trying to create an executable for distribution. 

What I'd like to be able to do is to include everything in the
library.zip *except* the tests directory and then as I (or whoever) 
creates more and more tests, have the ability to simply drop them into
the directory and the next time the app starts, it'll pick them up.
However, if I don't include the tests in library.zip, then when I hit
the "from tests import *", it complains "AttributeError: 'module' object
has no attribute 'test1'" when it gets to the first test.  And If I do
include the tests in the library.zip, it works with the tests that I
have now, but then I still can't add any new ones without the attribute
error unless I regenerate the exe every time. 

Basically, it seems like it comes down to importing a package outside
the library.zip.  So, is there any way to do this with py2exe?  Or even
another exe creating application? 

Thanks,

Jason

Hi,
Can you give me more info?  I mean, I've tried explicitly adding the
path to the package in my main py file via "sys.path.append(__path__[0]
+ '\\tests')".  But this does not seem to help.

Thanks,
Jason

Hi Again,
So, someone responded with some tips about paths, so my paths are
correct in the exe and I verified this by printing them out.  So, my
problem is not that, I guess.  And in my original email, I simplified my
scenario because I thought it was a problem with paths.  So, let me back
up a little.  

My tests directory actually has several sub-directories, so it's laid
out like this: tests/testCategory1, tests/testCategory2,
tests/testCategory1/subCategory1/test1, and so on.  With potentially
hundreds of tests, I needed some organization.  Anyway, in my tests
directory, I have an __init__.py with " __all__=["testCategory1",
"testCategory2"]" and it's this that the exe keeps choking on.  Even
though I append the path directly above the __all__ via "
sys.path.append(os.path.abspath('') + '\\tests')" and
"sys.path.append(os.path.abspath('') + '\\tests\\testCategory1')" (the
second one just to be safe), when I execute the import *, it still tells
me "AttributeError: 'module' object has no attribute 'testCategory1'"

Again, this works fine when just executing the python code without the
exe.  What am I doing wrong?  Or can anyone even point me to the right
place to possibly find an answer?

Thanks,
Jason

I tried already to point you in the right direction, but apparently that
didn't work for you. So now I don't really know.

If you add "C:/TEMP" to your sys.path, put there a python file, and try to
import it? Does that work? (To just begin with simple things).

Can you perhaps show us the value which you're adding to sys.path, just for
everyone to double-triple-check that what you're adding is correct?

Can you perhaps make a standalone sample consisting of 1 Python file with
'program', 1 Python file that needs to be imported, 1 Setup.py to make the
executable?
Then put the 'module' Python file in a fixed location (such as "C:/TEMP",
but anything goes) and add that fixed location to your sys.path.
Then test and if it still fails as EXE, there'll be a standalone testcase to
check.

--Tim

[Daniel Pryden <daniel@pr...>]

I think your problem is the "from package import *".  I would try using 
an __init__.py that imports all your sub-modules, or else just write 
some code to import modules manually.

For a previous project, I wrote code to find .py files in a directory 
and import classes from them as a "plugin" system for a frozen app (on 
Linux so not using py2exe), but I don't think I can distribute the code. 
  But that does seem like the right approach for what you're trying to 
do.  The trick is just some clever use of the __import__ function (see 
the Python docs for details) plus some run-time introspection of objects.

Re: [Py2exe-users] Importing a package not included in library.zip

[Jason Raff <jraff@ce...>]

Just to let you all know, I finally got this working via finding the
directories and files and then manually importing via some run-time
introspection of objects.  So, I guess py2exe just does not like "from
package import *" if it's not in the library.zip. The only problem now
is that the importing seems somewhat slower, but at least it does what I
want now.  Thanks for all your help.

Jason
