RuntimeError: Failed to load shared library ‘.../python3.11/site-packages/llama_cpp/lib/libllama.so‘_failed to load python shared library-优快云博客

安装xinference报错

 ERROR: Failed building wheel for llama-cpp-python
Failed to build llama-cpp-python
ERROR: Could not build wheels for llama-cpp-python, which is required to install pyproject.toml-based projects

后找到一个加速器

wget https://git.886.be/https://github.com/abetlen/llama-cpp-python/releases/download/v0.2.88-cu122/llama_cpp_python-0.2.88-cp311-cp311-linux_x86_64.whl

 pip install llama_cpp_python-0.2.88-cp311-cp311-linux_x86_64.whl

然后继续全量安装 xinference

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple "xinference[all]"

安装是成功的，

但是执行下面命令时

xinference --version

报错如下：

RuntimeError: Failed to load shared library '/root/anaconda3/envs/xin_env/lib/python3.11/site-packages/llama_cpp/lib/libllama.so': libcudart.so.12: cannot open shared object file: No such file or directory

这个错误信息表明在尝试加载 llama_cpp 库的共享对象 libllama.so 时，系统找不到 libcudart.so.12 这个文件。libcudart.so 是 NVIDIA CUDA 工具包中的一个关键运行时库，它提供了 CUDA 运行时 API。

检查 libcudart.so.12 文件是否存在：使用 find 命令来搜索这个文件。

sudo find / -name libcudart.so.12 2>/dev/null

结果


(xin_env) root@dell-Precision-5860-Tower:~# sudo find / -name libcudart.so.12 2>/dev/null
/root/anaconda3/envs/xin_env/lib/python3.11/site-packages/nvidia/cuda_runtime/lib/libcudart.so.12

设置 LD_LIBRARY_PATH 环境变量：如果 libcudart.so.12 文件存在，但系统找不到它，可能是因为它不在系统的库路径中。你可以通过设置 LD_LIBRARY_PATH 环境变量来解决这个问题。


export LD_LIBRARY_PATH=/root/anaconda3/envs/xin_env/lib/python3.11/site-packages/nvidia/cuda_runtime/lib:$LD_LIBRARY_PATH

同样，又爆出一个问题：

RuntimeError: Failed to load shared library '.../lib/python3.11/site-packages/llama_cpp/lib/libllama.so': libcublas.so.12: cannot open shared object file: No such file or directory

解决方法同样操作。


(xin_env) root@dell-Precision-5860-Tower:~# sudo find / -name libcublas.so.12 2>/dev/null
/root/anaconda3/envs/xin_env/lib/python3.11/site-packages/nvidia/cublas/lib/libcublas.so.12


export LD_LIBRARY_PATH=/root/anaconda3/envs/xin_env/lib/python3.11/site-packages/nvidia/cublas/lib:$LD_LIBRARY_PATH

再次执行

xinference --version
