 - `model`: The ONNX model to convert.
+- `feed_dict`: Test data used to measure the accuracy of the model during conversion. Format is similar to InferenceSession.run (map of input names to values)
 - `validate_fn`: A function accepting two lists of numpy arrays (the outputs of the float32 model and the mixed-precision model, respectively) that returns `True` if the results are sufficiently close and `False` otherwise. Can be used instead of or in addition to `rtol` and `atol`.
 - `rtol`, `atol`: Absolute and relative tolerances used for validation. See [numpy.allclose](https://numpy.org/doc/stable/reference/generated/numpy.allclose.html) for more information.
 - `keep_io_types`: Whether model inputs/outputs should be left as float32.
