问题简述：

在使用3张 RTX 3090 (24GB) 卡的 Ubuntu 20.04 环境下，加载 Qwen1.5-MoE-A2.7B-Chat-GPTQ-Int4 模型时，加载时间近2 小时（约 7096 秒）。即使安装flash-attn和auto_gptq库下，加载速度仍非常慢！

2024-07-17 17:29:02 - This IS NOT expected if you are initializing Qwen2MoeForCausalLM from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).
2024-07-17 17:41:54 Special tokens have been added in the vocabulary, make sure the associated word embeddings are fine-tuned or trained.
2024-07-17 17:41:55 The attention mask is not set and cannot be inferred from input because pad token is same as eos token.As a consequence, you may observe unexpected behavior. Please pass your input's `attention_mask` to obtain reliable results.
