Hugging Face Hub、XET 调试

调试、排查下载卡住、停止或下载缓慢的问题

下载卡在 90% 到 99%

如果您看到通过 hf download unsloth/* 下载在进度的 90% 或 99% 卡了很长时间，请取消当前运行，并尝试使用下面的命令添加：

pip install -U huggingface_hub

HF_HOME=".cache_new/huggingface" \
HF_XET_CACHE=".cache_new/huggingface/xet" \
HF_HUB_CACHE=".cache_new/huggingface/hub" \
HF_XET_HIGH_PERFORMANCE=1 \
HF_XET_CHUNK_CACHE_SIZE_BYTES=0 \
HF_XET_RECONSTRUCT_WRITE_SEQUENTIALLY=0 \
HF_XET_NUM_CONCURRENT_RANGE_GETS=64 \
hf download unsloth/Qwen3-Coder-Next-GGUF \
    --local-dir unsloth/Qwen3-Coder-Next-GGUF \
    --include "*UD-Q6_K_XL*"

受速率限制或 429 请求过多？

尝试使用 snapshot_download 代替，然后导入 Unsloth，Unsloth 会为您设置正确的 Hugging Face 变量：

import unsloth
import os

os.environ["HF_HOME"] = ".cache_new/huggingface"
os.environ["HF_XET_CACHE"] = ".cache_new/huggingface/xet"
os.environ["HF_HUB_CACHE"] = ".cache_new/huggingface/hub"
from huggingface_hub import snapshot_download
snapshot_download(
    repo_id = "unsloth/Qwen3-Coder-Next-GGUF",
    local_dir = "unsloth/Qwen3-Coder-Next-GGUF",
    allow_patterns = ["*UD-Q6_K_XL*"],
)

或者也可以先通过以下方式获取 Hugging Face 令牌 https://huggingface.co/settings/tokens

pip install -U huggingface_hub

HF_HOME=".cache_new/huggingface" \
HF_XET_CACHE=".cache_new/huggingface/xet" \
HF_HUB_CACHE=".cache_new/huggingface/hub" \
HF_XET_HIGH_PERFORMANCE=1 \
HF_XET_CHUNK_CACHE_SIZE_BYTES=0 \
HF_XET_RECONSTRUCT_WRITE_SEQUENTIALLY=0 \
HF_XET_NUM_CONCURRENT_RANGE_GETS=64 \
    hf download unsloth/Qwen3-Coder-Next-GGUF \
    --local-dir unsloth/Qwen3-Coder-Next-GGUF \
    --include "*UD-Q6_K_XL*" \
    --token "hf_ADD_YOUR_HUGGING_FACE_TOKEN_HERE"
