Tokenized (Llama 3) verison of NousResearch/dolma-v1_7-305B as a Nanotron dataset split into 10 GB chunks.

To download:

huggingface-cli download --repo-type dataset --local-dir dolma-v1_7-305B-tokenized-llama3-nanoset --local-dir-use-symlinks False NousResearch/dolma-v1_7-305B-tokenized-llama3-nanoset

To recombine:

cat dolma-v1_7-305B-tokenized-llama3-nanoset/dolma-v1_7-305B-tokenized-llama3-nanoset.npy.* > dolma-v1_7-305B-tokenized-llama3-nanoset.npy
rm -rf dolma-v1_7-305B-tokenized-llama3-nanoset

Can also be used directly with numpy, for example

import numpy as np

dataset_buffer_mmap = np.memmap("dolma-v1_7-305B-tokenized-llama3-nanoset.npy",
  mode="r", order="C", dtype=np.int32)
dataset_buffer = memoryview(dataset_buffer_mmap)
dataset_number_of_tokens = int(len(dataset_buffer))
