  • 全部weights要用fp32/tf32, 使用fp16微调十几或几十的步数后大概率loss=nan;(即便layer-norm是fp32也不行, LLaMA就没有这个问题, 原因暂时未知)

备注

1. 非常重要: 全部weights要用fp32/tf32, 使用fp16微调十几或几十的步数后大概率loss=nan;(即便layer-norm是fp32也不行, LLaMA就没有这个问题, 原因暂时未知)2. transformers需要4.38及以上;3. gemma词典大小为25w,多语言版本,包含繁/简体;4. gemma网络架构同Llama, gemma-2b为18层网络, gemma-7b为28层网络; 5. prompt:   5.1 标准格式为: bos + input + output + eos   5.2 prompt格式为: <start_of_turn>userinput<end_of_turn><start_of_turn>modeloutput<end_of_turn>6 微调输入输出:    输入:"<start_of_turn>user/n{问题}<end_of_turn>/n"    输出:"<start_of_turn>model/n{答案}<end_of_turn>"7 推理输入输出(assistant/n放置位置不同):    输入:"<start_of_turn>user/n{问题}<end_of_turn>/n<start_of_turn>model/n"    输出:"{答案}<end_of_turn>"8. 网络各层名称('model.embed_tokens.weight', torch.bfloat16, True)......('model.layers.17.self_attn.q_proj.weight', torch.bfloat16, True)('model.layers.17.self_attn.k_proj.weight', torch.bfloat16, True)('model.layers.17.self_attn.v_proj.weight', torch.bfloat16, True)('model.layers.17.self_attn.o_proj.weight', torch.bfloat16, True)('model.layers.17.mlp.gate_proj.weight', torch.bfloat16, True)('model.layers.17.mlp.up_proj.weight', torch.bfloat16, True)('model.layers.17.mlp.down_proj.weight', torch.bfloat16, True)('model.layers.17.input_layernorm.weight', torch.bfloat16, True)('model.layers.17.post_attention_layernorm.weight', torch.bfloat16, True)......('model.norm.weight', torch.bfloat16, True)9. RuntimeError: unscale_() has already been called on this optimizer since the last update().    微调语料太少导致的
