ok. Thanks a lot !
That is to say, under the datasets/datasets/xcopa/xcopa.py in the datasets  repository. I must to download the xcopa zip files remotely and get the cached files. Then i can load the cached datasets locally.
If i want to manully download the xcopa zip files and load it, i must to write another ‘xcopa.py’ (like you provided) to load the zip files locally. right?
