1.问题描述：

在使用Transformer或者SentenceTransformer时有时会遇到如下警告，甚是恼火！！！

2.错误：

WARNING:transformers.tokenization_utils_base:Truncation was not explicitely activated but max_length is provided a specific value, please use truncation=True to explicitely truncate examples to max length. Defaulting to ‘longest_first’ truncation strategy. If you encode pairs of sequences (GLUE-style) with the tokenizer you can select this strategy more precisely by providing a specific strategy to truncation.

3.解决方法：

import logging
logging.basicConfig(level=logging.ERROR)

4.特殊情况

当使用的是jupter notebook，添加完代码需要重启服务才可以哦！
