@ysu let me answer these questions for you
Q1: /lib64/libc.so.6: version `GLIBC_2.25’ not found (required by /tmp/ray/1682382173023/libcore_worker_library_java.so)
A1: Maybe you take a look for version of GLIBC, compile ‘‘libcore_worker_library_java.so’’ without specifying GLIBC version. I guess it’s caused by the compilation environment where GLIBC is 2.25, and you can take a look for version of GLIBC by “ldd --version”.
Building “libcore_worker_library_java.so” without specifying the version of GLiBC, I guess that the GLIBC version of the machine used to compile Ray is 2.25. Maybe you can take a look at version of GLIBC by command “ldd --version”. As you see, you can rebuild ray to solve the question.
@XiaodongLv Thanks a lot for this info. So just to confirm: if I update “ray-api” and “ray-runtime” to any released version >= 2.1.0, the libcore_worker_library_java.so would be compatible with our machine, right?
@XiaodongLv I tried to use the publicly released ray-api and ray-runtime 2.4.0, but unfortunately, the GLIBC issue occurs again. So the libcore_worker_library_java.so in the new version of ray-runtime is still not compatible with CentOS 3.9. Wondering if you could help take a look at the compiling way of that so file? Thanks.
I agree with @GuyangSong , because the glibc version of the machine where ray is released is 2.25, so you build ray on your computer will be successful.
@GuyangSong@XiaodongLv Thank you both for your response. So when can we expect the new version based on the compiling in the manylinux2014 image to be released?
@GuyangSong Thanks a lot! This is really helpful to us as we do not need to build the libs on our own and track the version. Please do keep us updated once the date is confirmed
Hi @GuyangSong , as we are waiting for the new libs that are compatible with CentOS 7.9, wondering if there is any update about when they will be released? Thanks.
@GuyangSong Thanks for the good news. W.r.t. the jar, wondering if you have a 2.4.0 version that I can try? Because we had some other issues with 2.0.0, we have updated the Python Ray to 2.4.0. So wondering if you could provide a snapshot version of ray-runtime-2.4.0 jar? Thanks again.
@jjyao Thanks for your response, but I assume this 2.4.0 is still the version that was built in the CI environment, right? That has caused the GLIBC issue (as described in the main post) for us, since it is not compatible with CentOS 7.9. That is why @GuyangSong proposed to build the jars on the manylinux2014 image (see here).
@ysu Actually, the jar which I pasted above is 2.4.0. The version name is “2.0.0-SNAPSHOT” now because it is built in ray OSS master CI and we didn’t use a real version. You can check it in your environment first and use the next release version when we release.
