Hi ! `load_dataset` accepts as input either a local dataset directory or a dataset name from the Hugging Face Hub.

So here you are getting this error the second time because it tries to load the local `wiki_dpr` directory, instead of `wiki_dpr` from the Hub. It doesn't work since it's a **cache** directory, not a **dataset** directory in itself.

To fix that you can use another cache directory like `cache_dir="/data2/whr/lzy/open_domain_data/retrieval/cache"` thx a lot
when I rerun my program, it occurs this error
" Unable to resolve any data file that matches '['**train*']' at /data2/whr/lzy/open_domain_data/retrieval/wiki_dpr with any supported extension ['csv', 'tsv', 'json', 'jsonl', 'parquet', 'txt', 'zip']", so how could i deal with this problem?
thx.
And below is my code .
