Several arguments in vLLMExporter.export and vLLMExporter.forward use None as a default but were annotated as non-optional str/int. This causes type-checker warnings and violates the documented signatures. Annotate them as Optional. Adds a static regression test that asserts every parameter with a None default in these methods is Optional. Signed-off-by: Andrew White <andrewh@cdw.com>

Bug
vLLMExporter.exportandvLLMExporter.forwarddeclare several parameters with a default ofNonebut annotate them as non-optionalstrorint(e.g.,tokenizer: str = None). This misrepresents the API and triggers type-checker warnings.Fix
Annotate all
None-default parameters asOptional[...].Test
Added a static regression test in
tests/unit_tests/export/test_vllm_exporter.pythat asserts every parameter defaulting toNonein these two methods is atyping.Union(i.e.,Optional).Verification
python -m py_compile nemo_export/vllm_exporter.py tests/unit_tests/export/test_vllm_exporter.pypasses.
