Thanks for your response. 0.3.0b3 is ok.
There is still minor path problem. Solved by adding path manually:

(inference) root@test:/mine# mooncake_master --version
/root/miniconda3/envs/inference/lib/python3.12/site-packages/mooncake/mooncake_master: error while loading shared libraries: libetcd_wrapper.so: cannot open shared object file: No such file or directory

(inference) root@test:/mine# find /root/miniconda3/envs/inference/ -name "libetcd_wrapper.so"
/root/miniconda3/envs/inference/lib/python3.12/site-packages/mooncake/libetcd_wrapper.so

(inference) root@test:/mine# export LD_LIBRARY_PATH=/root/miniconda3/envs/inference/lib/python3.12/site-packages/mooncake:$LD_LIBRARY_PATH
(inference) root@test:/mine# mooncake_master --version
mooncake_master

@xiaguan I think this could be caused by the conda env lib not in the LD_LIBRARY_PATH , correct?

Could you share your installation method so I can try to reproduce the issue?
auditwheel has already adjusted the relevant dynamic library search paths for us; it seems this issue shouldn't be occurring.
