LGTM, thanks @nikita-savelyevv !

Not related to this PR but I'm seeing a new error for export in fp16 (for sam and gpt2 models) with openvino-nightly which previously wasn't present, any chances you have an idea on what could be the cause ?

RuntimeError: Check 'node->constant_fold(outputs, node->input_values())' failed at src/core/src/xml_util/xml_serialize_util.cpp:59

Thanks @echarlaix! I don't have this understanding yet, we will investigate this internally.
