slow_tokenizer处理速度 我们本文使用的模型是uer/roberta-base-finetuned-dianping-chinese 这个模型可以里面的tokenizer的实现分为了rust实现和python实现,rust实现比较快我们代码中的fast_tokenizer 就是用rust来实现的,并且生成的对象的快慢我们通过use_fast=False这个参数来判断的 当我们使用 fast_tokenizer 时并且把参...

After #114 , the server decodes the running sequences every step. This leads to significant overhead, especially when the slow tokenizer is used (e.g., LLaMA). # opt-13b inference latency (bs 8, input 32, output 128) Avg latency: 3.57 se...
当前行为 | Current Behavior 准备将本地词表合并到Qwen的词表,但是发现Qwen tokenizer无论是fast还是普通的use_fast=False,也就是tokenization_qwen2.py和tokenization_qwen2_fast.py,均不支持“sp_model”,导入报错: 1.AttributeError: 'Qwen2Tokenizer' object has
