We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Use main instead of master to load the datasets
The main branch in https://github.com/huggingface/datasets is now `main`, not `master` anymore. Note that it's backward compatible, so no need to hurry

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
