Grid search 會產生多少個模型？

當下方的 cross-validator 對資料進行擬合時，會建立多少個模型？

params = ParamGridBuilder().addGrid(hasher.numFeatures, [1024, 4096, 16384]) \
                           .addGrid(hasher.binary, [True, False]) \
                           .addGrid(logistic.regParam, [0.01, 0.1, 1.0, 10.0]) \
                           .addGrid(logistic.elasticNetParam, [0.0, 0.5, 1.0]) \
                           .build()

cv = CrossValidator(..., estimatorParamMaps=params, numFolds=5)
