错误描述

使用llm/run_pretrain.py嘗試訓練"GPT3-1.3B"，初始化模型階段會發生錯誤:

    init_class = architectures.pop() if len(architectures) > 0 else None
TypeError: object of type 'NoneType' has no len()

architecture不知為何為None

稳定复现步骤 & 代码

python -u  -m paddle.distributed.launch --gpus "0,1" llm/run_pretrain.py --model_name_or_path gpt3-1.3B-en --output_dir output

[wawltor]

需要使用相应d的配置文件来训练，可以参考llama

[wawltor]

配置文件可以参考 https://github.com/PaddlePaddle/PaddleNLP/blob/develop/llm/config/gpt-3/pretrain_argument.json

[anderson101866]

了解，所以現在 --model_name_or_path gpt3-1.3B-en這種寫法是否不支持了呢? <--Q1

看起來以前可以從 paddlenlp/transformers/gpt/configuration.py:118導入， @wawltor Q2: 主要是想請教, 現在如何將上述預定義的GPT3-1.3B配置帶入run_pretrain.py中呢?

[wawltor]

目前主要是配置化的方式，上面的方式有可能会导致部分参数缺失；建议按照GPT的示例配置文件来适配

[anderson101866]

@wawltor 感謝你的回覆，然而不幸的是，看起來並非root-cause 仍然有問題

我照你的步驟建立 gpt3-1.3B-en.json

{
    "model_name_or_path": "gpt3-1.3B-en",
    "tokenizer_name_or_path": "gpt3-1.3B-en",
    "input_dir": "/workspace/dataset",
    "output_dir": "output/paddlenlp_gpt3/debug/model_output",
    "bf16": true,
    "sequence_parallel": true,
    "tensor_parallel_degree": 8,
    "sharding_parallel_degree": 1,
    "sharding": "stage2",
    "pipeline_parallel_degree": 1,
    "virtual_pp_degree": 1,
    "pipeline_parallel_config": "disable_partial_send_recv",
    "per_device_train_batch_size": 72,
    "per_device_eval_batch_size": 72,
    "gradient_accumulation_steps": 32,
    "split": "949,50,1",
    "max_seq_length": 2048,
    "fuse_attention_qkv": true,
    "use_flash_attention": true,
    "fp16_opt_level": "O2",
    "learning_rate": 0.00001,
    "min_learning_rate": 0.000005,
    "save_steps": 100000,
    "weight_decay": 0.01,
    "warmup_ratio": 0.01,
    "max_grad_norm": 1.0,
    "logging_steps": 1,
    "dataloader_num_workers": 1,
    "hidden_dropout_prob": 0.1,
    "attention_probs_dropout_prob": 0.1,
    "max_steps": 32,
    "eval_steps": 100000,
    "report_to": "visualdl",
    "disable_tqdm": true,
    "do_train": true,
    "continue_training": 0,
    "device": "gpu"
}

然後運行 python3 -u -m paddle.distributed.launch --gpus 0,1,2,3,4,5,6,7 --ips 127.0.0.1 --log_dir output/paddle_gpt3/debug llm/run_pretrain.py ./gpt3-1.3B-en.json

    init_class = architectures.pop() if len(architectures) > 0 else None

GP3-1.3B是公開的模型，要不要直接在你那邊覆現看看?
