There's an ONNX runtime, but to use the runtime you do need to convert your model into ONNX format first. You can't just run a TF of PyTorch model using the ONNX runtime directly. (At least last time I checked.) Unfortunately this conversion process can be a pain and there needs to be an equivalent operator in ONNX for each op in your TF/Torch execution graph.
