In the cavernous, dimly lit bridge of a starship, sleek metallic consoles with glowing amber displays flank a massive, curved observation window. A female captain, in her late 40s with an athletic build and short silver-streaked black hair, stands in the center midground. She wears a structured, high-collared dark navy military tunic with silver chest insignias. Her back is to the camera, silhouetted against the cool, ambient starlight pouring through the thick glass. She stands perfectly still with her hands clasped tightly behind her back. Outside the window, a massive armada of jagged, dark grey dreadnoughts hovers in tight formation against a deep purple space nebula. The fleets massive rear thrusters begin to glow with an intense, escalating bright blue light. [Shot 2] At 00:04.500, the camera cuts to a close-up of the captains face and shakes strongly. The brilliant blue-white light from the fleets gathering energy reflects vividly in her dark eyes. Suddenly, a blinding white flash floods through the window, completely washing out the background as the fleet jumps to hyperspace. The sheer spatial force violently jolts the bridge, causing the captain from Shot 1 to stagger slightly forward, her shoulders tensing as she visibly braces herself against the physical tremors. As the intense white light fades abruptly, leaving only the dim, empty expanse of the purple nebula reflected on her starkly lit skin, her jaw clenches, and she slowly closes her eyes in the newly emptied space. overall_soundscape: A low, resonant hum of the ships ambient life support systems serves as the baseline, soon drowned out by an audible, escalating, high-pitched electronic whine as the fleet outside charges its hyperdrives. A massive, deafening, bass-heavy boom and sharp crackle erupts during the blinding flash, accompanied by the loud metallic creaking, rattling, and deep thuds of the bridges bulkheads vibrating under immense physical stress. The intense roaring impact then cuts abruptly back to a hollow, echoing room tone, leaving only the faint, steady hum of the isolated bridge. non_diegetic_music: Cinematic space-opera orchestral score, slow tempo, featuring a solitary, mournful French horn melody over deep, sustained string dissonances that build rapidly in volume and intensity, swelling to a massive orchestral peak before snapping immediately into silence right after the jump.8. 常见问题与避坑8.1 外部访问 8188 超时SSH 通但 HTTP 不通根因UFW 防火墙未放行端口。修复sudo ufw allow 8188/tcp排查curl --noproxy * -m 5 http://SERVER_IP:8188/system_stats超时则查防火墙。8.2 生成视频 OOM根因torch 2.8 / 无 --lowvram / 分辨率过高。修复见 第 5 节。降分辨率到 640×360确认 --lowvram 已加。8.3 pip 安装大文件卡死根因清华源 100MB 文件易断流。修复用aria2c -c -x 16 -s 16 -k 1M多线程下载再pip install --no-deps本地 wheel。8.4 torch 显示未安装但进程在跑根因pip 中断安装残留~orch临时目录进程靠内存活着重启必崩。修复rm -rf venv/lib/python3.12/site-packages/~orch重新pip install --no-deps本地 wheel。8.5 vLLM 无法加载 INT8 权重事实vLLM 无法加载 ComfyUI 的 INT8 单文件权重只能用官方 diffusers 完整仓库FL2VA ~144GB BF16。磁盘不够时只能用 ComfyUI INT8。8.6 SSH 后台进程被杀根因SSH 通道关闭时 nohup 进程可能被杀。修复长任务用前台run_in_background保持连接或上传 shell 脚本后bash xxx.sh执行。8.7 conda create 卡 repodata根因国内 conda repodata 下载慢/卡。修复用venv miniforge python代替conda create。8.8 comfyui-workflow-templates 版本滞后根因清华镜像源滞后。修复从官方 PyPI 安装pip install comfyui-workflow-templates不加 -i 清华源。9. 快速命令速查从本机Windows通过 SSH 执行# 变量WBC:\Users\YOUR_USER\WorkBuddy\2026-08-21-11-15-25\.workbuddyNODEC:\Users\YOUR_USER\.workbuddy\binaries\node\versions\22.22.2\node.exeNPM_PATHC:\Users\YOUR_USER\.workbuddy\binaries\node\workspace\node_modules# 启动服务cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsbash /home/YOUR_USER/MiniMax-H3/start_comfyui.sh# 停止服务cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jskill \$(cat/home/YOUR_USER/MiniMax-H3/logs/comfyui.pid)2/dev/null; ps aux | grep main.py --listen | grep -v grep# 查看日志cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jstail -30 /home/YOUR_USER/MiniMax-H3/logs/comfyui.log# 验证服务cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jscurl -s -m 5 http://localhost:8188/system_stats# 检查 GPU 状态cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsnvidia-smi --query-gpuindex,name,memory.used,memory.total --formatcsv# 检查磁盘cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsdf -h / /home/YOUR_USER/synology# 检查进程cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsps aux | grep -E main.py|comfyui | grep -v grep服务器上直接执行# 启动bash/home/YOUR_USER/MiniMax-H3/start_comfyui.sh# 停止kill$(cat/home/YOUR_USER/MiniMax-H3/logs/comfyui.pid)# 日志tail-f/home/YOUR_USER/MiniMax-H3/logs/comfyui.log# 验证curl-shttp://localhost:8188/system_stats# 放行端口sudoufw allow8188/tcp# 检查 torch 版本/home/YOUR_USER/MiniMax-H3/venv/bin/python-cimport torch; print(torch.__version__)附录模型文件清单文件路径大小用途FL2VA INT8models/diffusion_models/minimax_h3_fl2va_pruned_int8_convrot.safetensors19.5GB主扩散模型Qwen3VLmodels/text_encoders/qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors14.6GB文本编码器Video VAEmodels/vae/minimax_h3_video_vae_fp16.safetensors4.85GB视频解码Audio VAEmodels/vae/minimax_h3_audio_vae_fp32.safetensors0.58GB音频解码Turbo LoRAmodels/loras/minimax_h3_fl2v_turbo_8step_v1.0_comfyui_bf16.safetensors1.8GB8步加速Ref2VA可选models/diffusion_models/minimax_h3_ref2va_pruned_int8_convrot.safetensors~20GB参考视频生成总计不含 Ref2VA~42GB

In the cavernous, dimly lit bridge of a starship, sleek metallic consoles with glowing amber displays flank a massive, curved observation window. A female captain, in her late 40s with an athletic build and short silver-streaked black hair, stands in the center midground. She wears a structured, high-collared dark navy military tunic with silver chest insignias. Her back is to the camera, silhouetted against the cool, ambient starlight pouring through the thick glass. She stands perfectly still with her hands clasped tightly behind her back. Outside the window, a massive armada of jagged, dark grey dreadnoughts hovers in tight formation against a deep purple space nebula. The fleets massive rear thrusters begin to glow with an intense, escalating bright blue light. [Shot 2] At 00:04.500, the camera cuts to a close-up of the captains face and shakes strongly. The brilliant blue-white light from the fleets gathering energy reflects vividly in her dark eyes. Suddenly, a blinding white flash floods through the window, completely washing out the background as the fleet jumps to hyperspace. The sheer spatial force violently jolts the bridge, causing the captain from Shot 1 to stagger slightly forward, her shoulders tensing as she visibly braces herself against the physical tremors. As the intense white light fades abruptly, leaving only the dim, empty expanse of the purple nebula reflected on her starkly lit skin, her jaw clenches, and she slowly closes her eyes in the newly emptied space. overall_soundscape: A low, resonant hum of the ships ambient life support systems serves as the baseline, soon drowned out by an audible, escalating, high-pitched electronic whine as the fleet outside charges its hyperdrives. A massive, deafening, bass-heavy boom and sharp crackle erupts during the blinding flash, accompanied by the loud metallic creaking, rattling, and deep thuds of the bridges bulkheads vibrating under immense physical stress. The intense roaring impact then cuts abruptly back to a hollow, echoing room tone, leaving only the faint, steady hum of the isolated bridge. non_diegetic_music: Cinematic space-opera orchestral score, slow tempo, featuring a solitary, mournful French horn melody over deep, sustained string dissonances that build rapidly in volume and intensity, swelling to a massive orchestral peak before snapping immediately into silence right after the jump.8. 常见问题与避坑8.1 外部访问 8188 超时SSH 通但 HTTP 不通根因UFW 防火墙未放行端口。修复sudo ufw allow 8188/tcp排查curl --noproxy * -m 5 http://SERVER_IP:8188/system_stats超时则查防火墙。8.2 生成视频 OOM根因torch 2.8 / 无 --lowvram / 分辨率过高。修复见 第 5 节。降分辨率到 640×360确认 --lowvram 已加。8.3 pip 安装大文件卡死根因清华源 100MB 文件易断流。修复用aria2c -c -x 16 -s 16 -k 1M多线程下载再pip install --no-deps本地 wheel。8.4 torch 显示未安装但进程在跑根因pip 中断安装残留~orch临时目录进程靠内存活着重启必崩。修复rm -rf venv/lib/python3.12/site-packages/~orch重新pip install --no-deps本地 wheel。8.5 vLLM 无法加载 INT8 权重事实vLLM 无法加载 ComfyUI 的 INT8 单文件权重只能用官方 diffusers 完整仓库FL2VA ~144GB BF16。磁盘不够时只能用 ComfyUI INT8。8.6 SSH 后台进程被杀根因SSH 通道关闭时 nohup 进程可能被杀。修复长任务用前台run_in_background保持连接或上传 shell 脚本后bash xxx.sh执行。8.7 conda create 卡 repodata根因国内 conda repodata 下载慢/卡。修复用venv miniforge python代替conda create。8.8 comfyui-workflow-templates 版本滞后根因清华镜像源滞后。修复从官方 PyPI 安装pip install comfyui-workflow-templates不加 -i 清华源。9. 快速命令速查从本机Windows通过 SSH 执行# 变量WBC:\Users\YOUR_USER\WorkBuddy\2026-08-21-11-15-25\.workbuddyNODEC:\Users\YOUR_USER\.workbuddy\binaries\node\versions\22.22.2\node.exeNPM_PATHC:\Users\YOUR_USER\.workbuddy\binaries\node\workspace\node_modules# 启动服务cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsbash /home/YOUR_USER/MiniMax-H3/start_comfyui.sh# 停止服务cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jskill \$(cat/home/YOUR_USER/MiniMax-H3/logs/comfyui.pid)2/dev/null; ps aux | grep main.py --listen | grep -v grep# 查看日志cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jstail -30 /home/YOUR_USER/MiniMax-H3/logs/comfyui.log# 验证服务cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jscurl -s -m 5 http://localhost:8188/system_stats# 检查 GPU 状态cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsnvidia-smi --query-gpuindex,name,memory.used,memory.total --formatcsv# 检查磁盘cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsdf -h / /home/YOUR_USER/synology# 检查进程cd$WBNODE_PATH$NPM_PATH$NODEssh-run.jsps aux | grep -E main.py|comfyui | grep -v grep服务器上直接执行# 启动bash/home/YOUR_USER/MiniMax-H3/start_comfyui.sh# 停止kill$(cat/home/YOUR_USER/MiniMax-H3/logs/comfyui.pid)# 日志tail-f/home/YOUR_USER/MiniMax-H3/logs/comfyui.log# 验证curl-shttp://localhost:8188/system_stats# 放行端口sudoufw allow8188/tcp# 检查 torch 版本/home/YOUR_USER/MiniMax-H3/venv/bin/python-cimport torch; print(torch.__version__)附录模型文件清单文件路径大小用途FL2VA INT8models/diffusion_models/minimax_h3_fl2va_pruned_int8_convrot.safetensors19.5GB主扩散模型Qwen3VLmodels/text_encoders/qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors14.6GB文本编码器Video VAEmodels/vae/minimax_h3_video_vae_fp16.safetensors4.85GB视频解码Audio VAEmodels/vae/minimax_h3_audio_vae_fp32.safetensors0.58GB音频解码Turbo LoRAmodels/loras/minimax_h3_fl2v_turbo_8step_v1.0_comfyui_bf16.safetensors1.8GB8步加速Ref2VA可选models/diffusion_models/minimax_h3_ref2va_pruned_int8_convrot.safetensors~20GB参考视频生成总计不含 Ref2VA~42GB
