H20服务器多卡运行有错误gpu_partition ，tmux错误
怎么修复
改 vcuda 配置 + 在一个tmux中启动本地 shim 服务：
cp -f /usr/local/lib/inais/.vcuda_config /usr/local/lib/inais/.vcuda_config.bak_$(date +%Y%m%d_%H%M%S) printf '22586\n127.0.0.1\n' > /usr/local/lib/inais/.vcuda_config cat /usr/local/lib/inais/.vcuda_config tmux set-environment -gu LOCAL_HOST_IP tmux set-environment -gu VCUDA_PORT tmux set-environment -gu INAIS_GPU_MEM_CONTAINER tmux set-environment -gu INAIS_GPU_MEM_DEV tmux set-environment -gu INAIS_GPU_MEM_POD unset LOCAL_HOST_IP VCUDA_PORT INAIS_GPU_MEM_CONTAINER INAIS_GPU_MEM_DEV INAIS_GPU_MEM_POD source /opt/conda/etc/profile.d/conda.sh && conda activate janusdna python /chenhaowen/hnu/mps/lora_deepseek_ocr_vision_DNA/script/rice_phenotype_benchmark/vcuda_pidmap_shim.py \ --host 127.0.0.1 \ --port 22586然后就可以运行自己的命令了
验证是否是对的：
看 shim 进程是否存在
pgrep -af vcuda_pidmap_shim.py
做最小 CUDA 验证：
source /opt/conda/etc/profile.d/conda.sh && conda activate janusdna && python -u - <<'PY'
import torch
print('cuda_available', torch.cuda.is_available())
torch.cuda.set_device(0)
x = torch.zeros(1, device='cuda:0')
print('alloc_ok', x.device)
