Hello,
A subset of the jsonl files from the RedPajama-Data-1T github have inconsistent schema and is causing problems when using

ds = load_dataset('json', data_files='/path_to/filtered_10f129bfd0af45caa9cd72aa9d863ec5.sampled.jsonl')

For that particular file we can see there are two entries with an additional "symlink_target" field. There are multiple jsonl files affected but not all.
To find the affected lines we can run:

awk '/symlink_target/ {print FNR}' filtered_10f129bfd0af45caa9cd72aa9d863ec5.sampled.jsonl

cat filtered_10f129bfd0af45caa9cd72aa9d863ec5.sampled.jsonl | grep "symlink_target"

This loading error is circumvented when using this loading method:

ds = load_dataset('togethercomputer/RedPajama-Data-1T', 'github',cache_dir="/path_to_folder_with_jsonl",streaming=True)['train']

but for our particular use case we need to use the load_dataset('json',..) approach.

Would it be possible to clean the dataset to make all entries with consistent schema?
