在QCS9075上部署Stable diffusion 2.1时遇到如下问题

weixin_38498942 2026-03-05 17:39:45

无法从Hugingface获取某些内容，例如：

'(MaxRetryError("HTTPSConnectionPool(host='huggingface.co', port=443): Max retries exceeded with url: /stabilityai/stable-diffusion-2-1-base/resolve/main/unet/config.json (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7f63e93610>: Failed to establish a new connection: [Errno 101] Network is unreachable'))"), '(Request ID: 4e87f358-0d0a-41dc-87a5-ba4cf79d15ce)')' thrown while requesting HEAD https://huggingface.co/stabilityai/stable-diffusion-2-1-base/resolve/main/unet/config.json
Retrying in 1s [Retry 1/5].

使用aarch64-ubuntu-gcc9.4的AP侧库运行：

解决方案与变通方法

有多种可能导致此问题。

该资源已从Huggingface移除。在这种情况下，我们需要使用社区版d2-community/stable-diffusion-2-1-base，而不是官方的stabilityai/stable-diffusion-2-1-base进行时间嵌入（更新Python模块[diffusers transformers]可能会有帮助，但我们尚未尝试）
中国大陆无法访问Huggingface。它需要一个VPN或执行中国大陆的生成。另一种推荐的方法是通过导出HF_ENDPOINT=https://hf-mirror.com/
分词器JSON文件clip-vit-large-patch14-tokenizer.json将从openai/clip-vit-large-patch14下载。不同的Python分词器版本可能会下载不同的JSON文件，且它们可能相互不兼容。

对于此SDK，V73 dsp没有适用于Ubuntu的对应存根。作为变通方法，即使平台是ubuntu-24.04-QCS9075，我们也使用aarch64-oe-linux-gcc9.4库/二进制文件
这是一个内核问题：
通过journalctl -k | grep dsp -i ，我们发现内核错误日志：
没有为FASTRPC保留DMA内存

关键冲突点：
在设备树中，“adsp - rpc - remote - heap”已被定义。
驱动程序报告错误：“没有为FASTRPC预留DMA内存”。
这强烈表明FastRPC驱动程序未能找到其应使用的预留内存区域。换句话说，FastRPC驱动程序的设备树节点没有正确引用这个预留内存节点。

QCS9075 部署 SD 2.1 — 速查

HuggingFace 网络不可达
板子无外网。在主机下载模型后 scp 推送到板子，或配置 https_proxy。
"Unsupported SoC 0" + 缺 libQnnHtp
用了错误的库路径。QCS9075 对应 HTP v79，设置：
export LD_LIBRARY_PATH=$QNN_SDK_ROOT/lib/aarch64-ubuntu-gcc9.4:$LD_LIBRARY_PATHexport ADSP_LIBRARY_PATH=$QNN_SDK_ROOT/lib/hexagon-v79/unsigned:$ADSP_LIBRARY_PATH
确认 QAIRT SDK >=2.28 且含 libQnnHtp.so、libQnnHtpV79Stub.so、libQnnHtpV79Skel.so。
错误码 1002 — DSP Transport 失败
RPC 会话建立不了。检查：
sudo chmod 666 /dev/adsprpc-smd # DSP 设备节点权限sudo systemctl start adsprpcd # FastRPC 守护进程dmesg | grep -i "cdsp|hexagon" # cDSP firmware 是否正常加载
ADSP_LIBRARY_PATH 必须指向 hexagon-v79/unsigned。
