Gpt2 vocab data is exact as the r50k_base vocab data, but with a different name.
1819
In the CompressFile task above we modify the file's content to elimenate the ranks, thus reducing the file size,
1920
since the rank corresponds to the line number in the file. For the file p50k_base.tiktoken,
2021
we introduce empty lines to replace any missing ranks, ensuring that the rank consistently aligns with the line number.
