Dolma

Dolma's official logo. It's dolma written in yellow, round lowercase letters over a blue background.

Dolma is a dataset of 3 trillion tokens from a diverse mix of web content, academic publications, code, books, and encyclopedic materials. It is openly released under AI2’s ImpACT license as a medium risk artifact.

More information:

Download

The fastest way to download Dolma is to directly download the individual files across multiple threads. This can be achieved using wget or aria2 Linux/Mac/Windows package (sudo apt-get install aria2 on Ubuntu).

For downloading individual files, simply use wget as follows:

wget --header 'Authorization: Bearer YOUR_HF_HUB_ACCESS_TOKEN' https://huggingface.co/datasets/allenai/dolma/resolve/main/data/peS2o/s2_v3-0000.json.gz

For downloading many files across multiple threads, first prepare a .txt file with the urls you would like such as via the script below:

OUT_DIRECTORY = "/scratch/dolma/data"

# URLs for cc_en_head
cc_en_head_base_url = "https://huggingface.co/datasets/allenai/dolma/resolve/main/data/common-crawl/cc_en_head/cc_en_head-"
cc_en_head_url_list = [f"{cc_en_head_base_url}{str(i).zfill(4)}.json.gz\n  dir={OUT_DIRECTORY}/cc_en_head\n  out=cc_en_head-{str(i).zfill(4)}.json.gz" for i in range(612)]

# URLs for cc_en_middle
cc_en_middle_base_url = "https://huggingface.co/datasets/allenai/dolma/resolve/main/data/common-crawl/cc_en_middle/cc_en_middle-"
cc_en_middle_url_list = [f"{cc_en_middle_base_url}{str(i).zfill(4)}.json.gz\n  dir={OUT_DIRECTORY}/cc_en_middle\n  out=cc_en_middle-{str(i).zfill(4)}.json.gz" for i in range(777)]

# URLs for cc_en_tail
cc_en_tail_base_url = "https://huggingface.co/datasets/allenai/dolma/resolve/main/data/common-crawl/cc_en_tail/cc_en_tail-"
cc_en_tail_url_list = [f"{cc_en_tail_base_url}{str(i).zfill(4)}.json.gz\n  dir={OUT_DIRECTORY}/cc_en_tail\n  out=cc_en_tail-{str(i).zfill(4)}.json.gz" for i in range(1493)]

# URLs for s2_v3
s2_v3_base_url = "https://huggingface.co/datasets/allenai/dolma/resolve/main/data/peS2o/s2_v3-"
s2_v3_url_list = [f"{s2_v3_base_url}{str(i).zfill(4)}.json.gz\n  dir={OUT_DIRECTORY}/peS2o\n  out=s2_v3-{str(i).zfill(4)}.json.gz" for i in range(42)]

# Print the combined list of URLs

    out.write(url + "\n")

Then you can download them all in parallel using:

aria2c --input-file files.txt --header 'Authorization: Bearer YOUR_HF_HUB_ACCESS_TOKEN'

You can also add -s to increase the number of connections, e.g. -s 10 (defaults to 5).

To get the exact file counts that are used for The Stack in the above script (LANG_TO_FILES), you can follow the below:

Fetch all files (does not download them, so should be fast): GIT_LFS_SKIP_SMUDGE=1 git clone git@hf.co:datasets/allenai/dolma.git Then run:

import os

directory = "dolma/data/stack-code"
folder_dict = {}

for folder in os.listdir(directory):
    folder_path = os.path.join(directory, folder)
    if os.path.isdir(folder_path):
        file_count = len([f for f in os.listdir(folder_path) if os.path.isfile(os.path.join(folder_path, f))])
        folder_dict[folder] = file_count

print(folder_dict)
