2024/10/02: 工具准备OK，但qemu运行时被killed
工具版本
Qemu：
Gcc版本：
Github Release
llama.cpp：
llama.cpp Github 10月2号pull
llama-7b模型版本：
Huggingface gguf文件
编译
llama.cpp编译
cd llama.cpp
make RISCV_CROSS_COMPILE=1
运行命令
qemu-riscv64 -L /home/kevin/data/projects/tools/riscv64_linux_gcc/sysroot -cpu rv64,v=true,vlen=256,elen=64,vext_spec=v1.0 ./llama-server -m /home/kevin/data/projects/kg_proj/rvv_transformer/codellama-7b.Q4_K_M.gguf -p “Anything” -n 9
问题
命令运行现象
可能原因
运行内存可能太小
2024/10/03: 使用10xE团队的最新版，解决tokenizer的问题，但还是被killed
最新版Github链接：
Tameem-10xE/llama.cpp Github
问题：运行7B模型被killed
运行现象
可能原因
有可能跟qemu运行的swapfile有关
可以团队成员提的一个issue：
Github Issue： qemu-riscv64 unexpectedly reached EOF error
解决办法
先尝试换一个更小的模型试试，不行就解决swapfile的问题
运行3B规模的model的现象：failed to allocate buffer of size
