## Required prerequisites - [x] Make sure you've read the documentation. Your issue may be addressed there. - [x] Search the issue tracker and discussions to verify that this hasn't already been reported. +1 or comment there if it has. ## What commit version of aidge do you use - ``aidge_core``: dev - ``aidge_backend_cpu``: dev - ``aidge_learning``: dev ## Problem description ``` ./setup.sh -m core -m backend_cpu && ./setup.sh -m learning -t ``` results in ``` 86% tests passed, 1 tests failed out of 7 Total Test time (real) = 0.54 sec The following tests FAILED: 4 - [loss/regression] MSE (Failed) Errors while running CTest ``` instead of tests succeeding. Also, all of the tests for snns (that are in branch leaky-backward in `aidge_learning`, since we need core,cpu and learning) are failing with an error in `getImpl()`. _Is this a regression ?_ Yes it is. It seems like the responsible is https://gitlab.eclipse.org/eclipse/aidge/aidge_core/-/commit/772300d6334014a716281e366ae02ec49aaaa634, since using `setDataType` fixes everything.
