During import, package collects basic information about the system, performs deep fingerprinting, and reports the data to the remote target. The package description attempts to build a false impression that it's an official package. The name refers to either ONNYX runtime, or the Pytorch package never released to the PyPI: https://github.com/pytorch/ort/blob/89466e524b0abe3a134418a50beeb405e287cedc/ort_moe/setup.py#L11
