How To Import *.pyc File From Different Version Of Python?

I used python 2.5 and imported a file named 'irit.py' from C:\util\Python25\Lib\site-packages directory. This files imports the file '_irit.pyc which is in the same directory. It w

Solution 1:

"DLL load failed" can't directly refer to the .pyc, since that's a bytecode file, not a DLL; a DLL would be .pyd on Windows. So presumably that _irit.pyc bytecode file tries to import some .pyd and that .pyd is not available in a 2.6-compatible version in the appropriate directory. Unfortunately it also appears that the source file _irit.py isn't around either, so the error messages end up less informative that they could be. I'd try to run python -v, which gives verbose messages on all module loading and unloading actions -- maybe that will let you infer the name of the missing .pyd when you compare its behavior in 2.5 and 2.6.

Solution 2:

Pyc files are not guaranteed to be compatible across python versions, so even if you fix the missing dll, you could still run in to problems.
