使用方式

更多样例sample详情见/test目录

1. (已默认/可配置)需要配置好预训练模型目录, 即变量 pretrained_model_dir、pretrained_model_name_or_path、idx等;
1. (已默认/可配置, 即训练, 验证集<非必要>)需要配置好自己的语料地址, 即字典 model_config["path_train"]、model_config["path_dev"]
1. (命令行/编辑工具直接run)cd到该脚本目录下运行普通的命令行即可, 例如: python3 slRun.py , python3 tcRun.py , python3 tet_tc_base_multi_label.py, python3 tet_sl_base_crf.py
1. (注意)如果训练时候出现指标为零或者很低的情况, 大概率是学习率、损失函数配错了
