Usage:
hfd <repo_id> [--include include_pattern] [--exclude exclude_pattern] [--hf_username username] [--hf_token token] [--tool aria2c|wget] [-x threads] [--dataset] [--local-dir path]
Description:
Downloads a model or dataset from Hugging Face using the provided repo ID.
Parameters:
repo_id The Hugging Face repo ID in the format 'org/repo_name'.
--include (Optional) Flag to specify a string pattern to include files for downloading.
--exclude (Optional) Flag to specify a string pattern to exclude files from downloading.
include/exclude_pattern The pattern to match against filenames, supports wildcard characters. e.g., '--exclude *.safetensor', '--include vae/*'.
--hf_username (Optional) Hugging Face username for authentication. **NOT EMAIL**.
--hf_token (Optional) Hugging Face token for authentication.
--tool (Optional) Download tool to use. Can be aria2c (default) or wget.
-x (Optional) Number of download threads for aria2c. Defaults to 4.
--dataset (Optional) Flag to indicate downloading a dataset.
--local-dir (Optional) Local directory path where the model or dataset will be stored.
Example:
hfd bigscience/bloom-560m --exclude *.safetensors
hfd meta-llama/Llama-2-7b --hf_username myuser --hf_token mytoken -x 4
hfd lavita/medical-qa-shared-task-v1-toy --dataset
