Import error

changed the description

It looks like you have two versions of Aidge, one with python 3.8 and 3.10.

I think you should try to remove the file /mnt/d/farges/Documents/aidge/env_aidge/lib/python3.8/site-packages/aidge_backend_cpu/aidge_backend_cpu.cpython-310-x86_64-linux-gnu.so which I suspect generate the error.

Cheers,

Cyril

Thank you @cmoineau but it doesn't solve:

I will try to reinstall aidge_backend_cpu .

The strange thing is that installing again generate again the 310 lib :

I think you should try to remove egg and build files before reinstalling as they may cache some informations.

And the RECORD of the dist-info indicates this file:

Removing build and egg, generates only one lib but doesn't remove the error:

I found one way to bypass the problem: I added a line "from aidge_backend_cpu import *" before "import aidge_backend_cpu". If this is the new way to import the module, the issue can be closed. Otherwise I guess that adding this line in the init().py may solve the issue.

No, this is not the new way to import backends, I am confused about this behavior.

Especially since I cannot reproduce it...

I understood the problem. The mistake is mine: import should not be done from inside the package folder. See:
