你好，当我试图把训练数据集改为DoubanBook和DoubanMoive的时候报了以下错误：（我按照https://github.com/RUCAIBox/RecBole-CDR/blob/main/results/Douban.md的内容修改properties文件）

<module 'recbole_cdr.data.dataset' from '/data/guzeng/RecBole-CDR/recbole_cdr/data/dataset.py'> Traceback (most recent call last): File "run_recbole_cdr.py", line 22, in run_recbole_cdr(model=args.model, config_file_list=config_file_list) File "/data/guzeng/RecBole-CDR/recbole_cdr/quick_start/quick_start.py", line 41, in run_recbole_cdr dataset = create_dataset(config) File "/data/guzeng/RecBole-CDR/recbole_cdr/data/utils.py", line 72, in create_dataset dataset = dataset_class(config) File "/data/guzeng/RecBole-CDR/recbole_cdr/data/dataset.py", line 312, in init self.source_domain_dataset = CrossDomainSingleDataset(source_config, domain='source') File "/data/guzeng/RecBole-CDR/recbole_cdr/data/dataset.py", line 31, in init super().init(config) File "/data/guzeng/anaconda3/envs/py37/lib/python3.7/site-packages/recbole/data/dataset/dataset.py", line 96, in init self._from_scratch() File "/data/guzeng/anaconda3/envs/py37/lib/python3.7/site-packages/recbole/data/dataset/dataset.py", line 106, in _from_scratch self._load_data(self.dataset_name, self.dataset_path) File "/data/guzeng/anaconda3/envs/py37/lib/python3.7/site-packages/recbole/data/dataset/dataset.py", line 246, in _load_data self._download() File "/data/guzeng/anaconda3/envs/py37/lib/python3.7/site-packages/recbole/data/dataset/dataset.py", line 218, in _download url = self._get_download_url('url') File "/data/guzeng/anaconda3/envs/py37/lib/python3.7/site-packages/recbole/data/dataset/dataset.py", line 213, in _get_download_url f'Neither [{self.dataset_path}] exists in the device' ValueError: Neither [dataset/DoubanBook] exists in the devicenor [DoubanBook] a known dataset name.

请问RecBole-CDR有相关的使用文档吗？谢谢

您好！ @bachml 推测这里您没有指定数据所在的路径，因此RecBole-CDR无法找到对应的数据。 您可以通过设置'data_path'参数来制定数据路径，修改我们的标准配置如下：

source_domain:
  dataset: DoubanBook
  data_path: dataset/Douban/
  USER_ID_FIELD: user_id
  ITEM_ID_FIELD: item_id
  RATING_FIELD: rating
  TIME_FIELD: timestamp
  NEG_PREFIX: neg_
  LABEL_FIELD: label
  load_col:
    inter: [user_id, item_id, rating]
  user_inter_num_interval: "[5,inf)"
  item_inter_num_interval: "[5,inf)"
  val_interval:
    rating: "[3,inf)"
  drop_filter_field: True

target_domain:
  dataset: DoubanMovie
  data_path: dataset/Douban/
  USER_ID_FIELD: user_id
  ITEM_ID_FIELD: item_id
  RATING_FIELD: rating
  TIME_FIELD: timestamp
  NEG_PREFIX: neg_
  LABEL_FIELD: label
  load_col:
    inter: [user_id, item_id, rating]
  user_inter_num_interval: "[5,inf)"
  item_inter_num_interval: "[5,inf)"
  val_interval:
    rating: "[3,inf)"
  drop_filter_field: True

epochs: 500
train_batch_size: 4096
eval_batch_size: 409600
valid_metric: NDCG@10

另外关于使用文档，我们继承自主工具包RecBole，绝大多数使用细节是相通的，您可以参考RecBole的使用文档来进行对照。

@bachml [Solved] Solution: change the local "overall.yaml" file I had faced similar error: you can edit in this file --RecBole/recbole/properties/overall.yaml --line number 8: "data_path: 'dataset/" to >> data_path: '/content/RecBole/dataset/' (i was using Google colab)
