How can I import a * .pyc file from another version of python?

I used python 2.5 and imported a file called "irit.py" from the C: \ util \ Python25 \ Lib \ site-packages directory. These files will import the "_irit.pyc" file located in the same directory. He worked well and did what I wanted. Than, I tried the same with python version 2.6.4. "irit.py" which is located in the C: \ util \ Python26 \ Lib \ site-packages folder was imported, but "_irit.pyc" (which is in the same directory out of 26 as before) was not found. I got the error:

File "C: \ util \ Python26 \ lib \ site-packages \ irit.py", line 5, in import _irit ImportError: Error loading DLL: The specified module was not found.

Can someone help me understand the problem and how to fix it? Thank you, Almog.

"DLL Load Error" cannot be directly referenced .pyc

as it is a bytecode file and not a DLL; DLL will be .pyd

in Windows. So it is presumed that the _irit.pyc

bytecode file is trying to import some .pyd

and that is .pyd

not available in the 2.6-compatible version in the appropriate directory. Unfortunately, it also seems like the original file _irit.py

is not there either, so the error messages become less informative than they might be. I will try to run python -v

one that gives detailed messages about all the actions to load and unload modules - perhaps this will allow you to print the name of the missing one .pyd

when comparing its behavior in versions 2.5 and 2.6.

Pyc files are not guaranteed to be compatible between python versions, so even if you fix the missing dll, you can still run into problems.
