脚本
data = np.array([["a", "10.0, 100"],\
["b", "-2.5, 9"],\
["c", "100.2, 1"],\
["d", "-99.9, 100"],\
["a", "1.4, 1"],\
["b", "-2.2, 9"],\
["c", "100.9, 1"]])
df = pd.DataFrame({"col" : data[:,0], "vec" : data[:,1]})
data = dataframeToOperator(df, schemaStr="col string, vec string",op_type="batch")
trainOp = VectorMinMaxScalerTrainBatchOp()\
.setSelectedCol("vec")
model = trainOp.linkFrom(data)
batchPredictOp = VectorMinMaxScalerPredictBatchOp()
batchPredictOp.linkFrom(model, data).collectToDataframe()
