Python导入钩子在导入之前复制PYD

Question

I have a large amount of .pyd modules that are ran of a network, my problem is that when they are used, they are file locked and i can't overwrite them. So I'm looking into having an import hook that would duplicate the .pyd to lets say a .pydlocked and load that instead, leaving the .pyd free to be replaced. I can't find very clear information on how to hook that in the import system. That sounds feasable as it's kind of what the .py to .pyc does.

Any ideas ?

PS : I know its hacky but this is for a very particular usage and I don't have other real good solutions in mind. The ideal would be to not have a file lock on the original .pyd but it doesn't seem possible.

Thanks !
