 ONNX Runtime
 enables high-performance evaluation of trained machine learning (ML)
-models while keeping resource usage low.
-Building on Microsoft's dedication to the
-`Open Neural Network Exchange (ONNX) <https://onnx.ai/>`_
-community, it supports traditional ML models as well
-as Deep Learning algorithms in the
-`ONNX-ML format <https://github.com/onnx/onnx/blob/master/docs/IR.md>`_.
-Documentation is available at
-`Python Bindings for ONNX Runtime <https://aka.ms/onnxruntime-python>`_.
-
-Example
--------
-
-The following example demonstrates an end-to-end example
-in a very common scenario. A model is trained with *scikit-learn*
-but it has to run very fast in a optimized environment.
-The model is then converted into ONNX format and ONNX Runtime
-replaces *scikit-learn* to compute the predictions.
-
-::
-
-    # Train a model.
-    from sklearn.datasets import load_iris
-    from sklearn.model_selection import train_test_split
-    from sklearn.ensemble import RandomForestClassifier
-    iris = load_iris()
-    X, y = iris.data, iris.target
-    X_train, X_test, y_train, y_test = train_test_split(X, y)
-    clr = RandomForestClassifier()
-    clr.fit(X_train, y_train)
-
-    # Convert into ONNX format with onnxmltools
-    from skl2onnx import convert_sklearn
-    from skl2onnx.common.data_types import FloatTensorType
-    initial_type = [('float_input', FloatTensorType([1, 4]))]
-    onx = convert_sklearn(clr, initial_types=initial_type)
-    with open("rf_iris.onnx", "wb") as f:
-        f.write(onx.SerializeToString())
-
-    # Compute the prediction with ONNX Runtime
-    import onnxruntime as rt
-    import numpy
-    sess = rt.InferenceSession("rf_iris.onnx")
-    input_name = sess.get_inputs()[0].name
-    label_name = sess.get_outputs()[0].name
-    pred_onx = sess.run([label_name], {input_name: X_test.astype(numpy.float32)})[0]
