读取数据问题

[MonkeyTB]

https://github.com/shibing624/textgen/blob/0339b3ed20004a677eb1250ac53ff132fe64e9a0/examples/chatglm/training_chatglm_adgen_demo.py#L47 你好，麻烦请问一下，这里这样读取数据后，在 chatglm_model.py第243-245显示读取的数据为空，这里应该怎么理解？

[MonkeyTB]

补充一下：训练会报错数据为空

[shibing624]

没下载ADGEN 数据集吗？

我用了今天新更新的代码，数据就没问题了，一脸懵逼，看代码就是少了个filter 有个很奇怪的问题 2023-04-13 11:51:18.354 | INFO | chatglm.chatglm_model:train_model:283 - Training/evaluation parameters TrainingArguments( _n_gpu=3, adafactor=False, adam_beta1=0.9, adam_beta2=0.999, adam_epsilon=1e-08, auto_find_batch_size=True, bf16=False, bf16_full_eval=False, data_seed=None, dataloader_drop_last=False, dataloader_num_workers=0, dataloader_pin_memory=True, ddp_bucket_cap_mb=None, ddp_find_unused_parameters=None, ddp_timeout=1800, debug=[], deepspeed=None, disable_tqdm=False, do_eval=False, do_predict=False, do_train=False, eval_accumulation_steps=None, eval_delay=0, eval_steps=None, evaluation_strategy=no, fp16=True, fp16_backend=auto, fp16_full_eval=False, fp16_opt_level=O1, fsdp=[], fsdp_config={'fsdp_min_num_params': 0, 'xla': False, 'xla_fsdp_grad_ckpt': False}, fsdp_min_num_params=0, fsdp_transformer_layer_cls_to_wrap=None, full_determinism=False, gradient_accumulation_steps=1, gradient_checkpointing=False, greater_is_better=None, group_by_length=False, half_precision_backend=auto, hub_model_id=None, hub_private_repo=False, hub_strategy=every_save, hub_token=<HUB_TOKEN>, ignore_data_skip=False, include_inputs_for_metrics=False, jit_mode_eval=False, label_names=None, label_smoothing_factor=0.0, learning_rate=0.0002, length_column_name=length, load_best_model_at_end=False, local_rank=-1, log_level=passive, log_level_replica=warning, log_on_each_node=True, logging_dir=./result//logs, logging_first_step=False, logging_nan_inf_filter=True, logging_steps=50, logging_strategy=steps, lr_scheduler_type=linear, max_grad_norm=1.0, max_steps=-1, metric_for_best_model=None, mp_parameters=, no_cuda=False, num_train_epochs=1, optim=adamw_torch, optim_args=None, output_dir=./result/, overwrite_output_dir=True, past_index=-1, per_device_eval_batch_size=1, per_device_train_batch_size=1, prediction_loss_only=False, push_to_hub=False, push_to_hub_model_id=None, push_to_hub_organization=None, push_to_hub_token=<PUSH_TO_HUB_TOKEN>, ray_scope=last, remove_unused_columns=False, report_to=['tensorboard', 'wandb'], resume_from_checkpoint=None, run_name=./result/, save_on_each_node=False, save_steps=400, save_strategy=steps, save_total_limit=3, seed=42, sharded_ddp=[], skip_memory_metrics=True, tf32=None, torch_compile=False, torch_compile_backend=None, torch_compile_mode=None, torchdynamo=None, tpu_metrics_debug=False, tpu_num_cores=None, use_ipex=False, use_legacy_prediction_loop=False, use_mps_device=False, warmup_ratio=0.0, warmup_steps=0, weight_decay=0.0, xpu_backend=None, ) 2023-04-13 11:51:18.501 | INFO | chatglm.chatglm_model:train_model:297 - *** Train *** wandb: (1) Create a W&B account wandb: (2) Use an existing W&B account wandb: (3) Don't visualize my results wandb: Enter your choice: 0 wandb: WARNING Invalid choice wandb: Enter your choice:

1. 是n_gpu=3?但是我找了所有配置和赋值，没有发现在哪里赋值的3，配置文件我看是1
2. wandb 这是什么？让我手动输入 enter you choice，多次输入之后（瞎输入）就或出现下面的连接 wandb: You chose 'Create a W&B account' wandb: Create an account here: https://wandb.ai/authorize?signup=true wandb: Paste an API key from your profile and hit enter, or press ctrl+c to quit:

[shibing624]

那就用最新代码，wandb是训练日志记录，不用管。

大佬，这个不管不进行训练，我去屏蔽了import wandb也还是会弹出来这个，强制性要我输入

我注册了一个账号，输入了40位的 key ，还是不行😓

大佬，这里感觉有点问题，
`input_ids = prompt_ids + target_ids` 
应该改为
`input_ids = prompt_ids + [tokenizer.bos_token_id] + target_ids`
在chatglm_model.py中这里找的是prompt的bos_token_id对prompt部分进行ignore
`    def data_collator(self, batch):
        len_ids = [len(example) for example in batch]

不知道我这里理解的对不对

感谢，我实在没办法，卸载了wandb就可以了，我装上再试试这个😓

没错，因为prompt_ids 默认是有 add_special_tokens=True，里面会带有bos + gmask

我在排查排查吧，我设置为True，会补两个0，也就是两个gmask，不会补bos的token_id。感谢开源

这里的： 130001 130004

130001就是bos, 130004就是gmask

add special tokens True: [5, 66219, 1389, 64812, 69171, 0, 0]
add special tokens False [5, 66219, 1389, 64812, 69171]

更改ice_text.model之后就正常了
add special tokens True: [5, 66219, 1389, 64812, 69171, 130001, 130004]
add special tokens False [5, 66219, 1389, 64812, 69171]
之前更新的和没跟新的好像没有完全替代，导致出现了混乱。没更新之前打印 tokenizer.gmask_token_id = 0，目前更新后没有问题了，正常运行了
