脚本示例

脚本

  1. data = np.array([["a", "10.0, 100"],\
  2. ["b", "-2.5, 9"],\
  3. ["c", "100.2, 1"],\
  4. ["d", "-99.9, 100"],\
  5. ["a", "1.4, 1"],\
  6. ["b", "-2.2, 9"],\
  7. ["c", "100.9, 1"]])
  8. df = pd.DataFrame({"col" : data[:,0], "vec" : data[:,1]})
  9. data = dataframeToOperator(df, schemaStr="col string, vec string",op_type="batch")
  10. trainOp = VectorMinMaxScalerTrainBatchOp()\
  11. .setSelectedCol("vec")
  12. model = trainOp.linkFrom(data)
  13. batchPredictOp = VectorMinMaxScalerPredictBatchOp()
  14. batchPredictOp.linkFrom(model, data).collectToDataframe()
