“为什么在删除列文本后不删除？在Dl4j转换中”

Question

“我正在尝试训练NN，但是在csv中使用文本时遇到了问题，所以我决定从中删除所有文本。”

“我正在尝试从csv文件中删除文本，但文本没有删除”

TransformProcess tp = new TransformProcess.Builder(schema)
  .removeColumns("MSZoning","Street","Alley","LotConfig","LotShape","LandContour","RoofMatl","LotConfig",
                               "BsmtCond",
                               "Utilities","LandSlope", "Neighborhood", "Condition1", "Condition2", "BldgType",
                               "HouseStyle", "RoofStyle",  "Exterior1st", "Exterior2nd", "MasVnrType", "ExterQual",
                               "ExterCond", "Foundation", "BsmtQual", "BsmtExposure",
                               "BsmtFinType1", "BsmtFinType2", "Heating", "HeatingQC", "CentralAir",  "KitchenQual",
                               "Functional", "FireplaceQu", "GarageType",
                               "GarageFinish", "GarageQual", "GarageCond", "PavedDrive", "PoolQC", "Fence",

看这个例子：https://github.com/eclipse/deeplearning4j-examples/blob/master/datavec-examples/src/main/java/org/datavec/transform/basic/BasicDataVecExample.java

您需要在TransformProcess上调用tp.build()，然后获取生成的模式：

Schema outputSchema = tp.getFinalSchema();
