Change it so that my_imported_mod imports my_main_mod. If A depends on B, then A should import B, not the other way around. If there's some good reason why B imports A despite this (and there could be--say if myfun is some kind of a callback), then you should probably pass myfun to the function in the imported module as an argument. If that's not practical, put myfun into a third module, and have my_imported_mod import that. If you want to live dangerously, you could do something like this from my_main_mod: import my_imported_mod my_imported_mod.myfun = myfun I don't recommend it, though, because my_imported_mod is no longer self-contained (i.e., it's a module not modular). -- CARL BANKS

Importing from filesystem path a 'frozen sub-module' error
by Calvin Spealman March 1, 2005

March 1, 2005

I've been working on a small test runner script, to accumulate my test scripts (all python files in the 'test' sub-directories of my source tree). Things were going well, but I'm still having trouble loading the modules, once I have a path to the python source file. This is the error I am getting: mod_info = imp.find_module(module_name, module_path) ImportError: No frozen submodule named PyInvolgo.test.test_RepoBase I know 100% sure the module exists (I can enter a python shell and import it directly, no problem), so that isn't the problem. I don't know what a 'frozen sub-module' is, tho, and I haven't been able to find anything about them from google searches and documentation on python.org. At first, I thought maybe it was because the test directory had no __init__.py (it isn't a package, so I didn't make one), but added one made no difference. --
