upload_to_hf.sh

#!/usr/bin/env bash
# 用临时 Hugging Face token 分目录并行上传，不修改系统已登录账号。
#
# 用法:
#   HF_TOKEN="hf_xxxx" REPO_ID="username/repo-name" ./upload_to_hf.sh
#
# 可选环境变量:
#   REPO_TYPE    model | dataset | space     (默认 dataset)
#   PRIVATE      1=私有  0=公开              (默认 1)
#   SRC_DIR      本地源目录                    (默认脚本所在目录)
#   PARALLEL     同时上传的顶层项数量          (默认 3)
#   NUM_WORKERS  每个大目录内部的 worker 数    (默认 4)
#   LOG_DIR      日志与暂存目录                (默认 $SRC_DIR/.hf_upload_logs)
#   RETRY        失败重试次数                  (默认 5)
