ONNX and Standard Machine Learning Tutorial¶

The tutorial goes from a simple example which converts a pipeline to a more complex example involving operator not actually implemented in ONNX operators or ONNX ML Operators.

The tutorial was tested with following version:

<<<

import sys
import numpy
import scipy
import onnx
import onnxruntime
import lightgbm
import xgboost
import sklearn
import onnxconverter_common
import onnxmltools
import skl2onnx
import pyquickhelper
import mlprodict
import onnxcustom

print("python {}".format(sys.version_info))
mods = [numpy, scipy, sklearn, lightgbm, xgboost,
        onnx, onnxmltools, onnxruntime, onnxcustom,
        onnxconverter_common,
        skl2onnx, mlprodict, pyquickhelper]
mods = [(m.__name__, m.__version__) for m in mods]
mx = max(len(_[0]) for _ in mods) + 1
for name, vers in sorted(mods):
    print("{}{}{}".format(name, " " * (mx - len(name)), vers))
