名称
read_ocr_class_knnT_read_ocr_class_knnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn — Read an OCR classifier from a file.
参数签名
def read_ocr_class_knn(file_name: str) -> HHandle
描述
read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn reads an OCR classifier that has been
stored with write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
