What this does
Simplifies the use of the dataset by looking for files locally first, then pulling from the hub if needed. By setting the argument
force_cache_sync=True, this behavior can be overridden and force syncing local files from the hub first.Also eliminate the hub branch convention we used so far to determine the version of a dataset. The value from
codebase_versionin theinfo.jsonis now the single source of truth to determine with what version of LeRobot a dataset was created.We will only use the
mainbranch by default, but one can specify a branch or commit by using the newrevisionarg. If thisrevisionis not available on the hub, the latest available version will be downloaded.How it was tested
v2.0dataset on this branch (e.g. lerobot/pusht) correctly displays a warning:v2.1dataset on the main branch still works with no issue (e.g. aliberts/koch_tutorial)
