签名
def read_class_train_data(file_name: str) -> HHandle
描述
read_class_train_dataread_class_train_dataReadClassTrainDataReadClassTrainDataReadClassTrainDataread_class_train_data reads the saved training data for classifiers
from the file FileNameFileNameFileNameFileNamefileNamefile_name (see write_class_train_datawrite_class_train_dataWriteClassTrainDataWriteClassTrainDataWriteClassTrainDatawrite_class_train_data).
The default HALCON file extension for training data for a
classifier is 'ctd'.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。
参数
FileNameFileNameFileNameFileNamefileNamefile_name (输入控制) filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)
File name of the training data.
