K2 sherpa编译使用

编译安装

1. pip卸载cmake、torch、k2
2. 安装 cmake 3.22.3版本、k2、kaldi_feat【官方提供|install_dir】、torch==2.0.1【】
3. 缺cuda

export LD_LIBRARY_PATH=/usr/local/cuda11.7/lib64:$LD_LIBRARY_PATH
export PATH=/usr/local/cuda11.7/include:/usr/local/cuda11.7/bin:$PATH
# libcupti.so.11.7
export LD_LIBRARY_PATH=/usr/local/cuda11.7/extras/CUPTI/lib64:/ceph/***/software/cuda-11.7.1/lib:$LD_LIBRARY_PATH

4. 缺 libcupti.so.11.7
   export LD_LIBRARY_PATH=/usr/local/cuda11.7/extras/CUPTI/lib64:/ceph/***/software/cuda-11.7.1/lib:$LD_LIBRARY_PATH
5. 缺libnccl.so.2
   /ceph/***/install_dir/nccl_2.13.4-1+cuda11.7_x86_64/lib

常见错误

1. libcuda.so.1: wrong ELF class: ELFCLASS32

将32位依赖库改成64位依赖库
