Problem description

When forwarding a GraphView containing a Split Operator with its 'split' attribute as input (and not attribute), I get the following error:

Split_Op: ignoring non-empty Split attribute because input#1 takes precedence
Assertion failed: it != C::registry().cend() in /aidge/aidge/aidge_core/include/aidge/utils/Registrar.hpp:80
missing or invalid registrar key: ("cpu", "UInt64") for registrable object N5Aidge6TensorE
Did you include/import the corresponding module?
If so, it is possible that the object is not yet supported.
