version `GLIBC_2.27' not found

[langzeng]

Hi, I'm trying to install torch in R on a server through install_torch(). It comes with the error:

Error in cpp_lantern_init(file.path(install_path(), "lib")) :
.../R/lib/liblantern.so - /lib64/libm.so.6: version `GLIBC_2.27' not found (required by .../R/lib/./libtorch_cpu.so)

The GLIBC version on the server is 2.17 and I can not update the version. Do you have any idea how to solve the problem? I was thinking to install a previous version of torch by install_torch(version="previous version") but it seems don't work.

I'm able to use Python (3.8) and PyTorch (1.13.1) on that server. Is that possible to force R Torch installation to use the existing python like:
library(reticulate)
use_python("...python3.8/bin/python")

did you find a solution to this issue?

Hi, setting Sys.setenv(PRECXX11ABI=1) and then install_torch() should fix, as this will install LibTorch with pre C++ 11 that doesn't require a newer Glibc.

I'll close for now, please reopen if you still have problems.

thanks! that solved the problem, sorry, your first answer got lost in my inbox.

This fix does not work for the new torch version which requires glibc 2.29. Is there any other way to get torch working without glibc 2.29?

@ykaeber , what's your OS version ? I can try taking a look, but would need more info.

I am getting the same issue as @ykaeber, same error message when installing torch 0.14.2.
This is the OS version:

lsb_release -a
LSB Version:	:core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID:	RedHatEnterprise
Description:	Red Hat Enterprise Linux release 8.10 (Ootpa)
Release:	8.10
Codename:	Ootpa

I am working on an HPC system, so I have no control over what GLIBC is installed. The version installed currently is 2.28:

ldd --version
ldd (GNU libc) 2.28

For now I have downgraded to torch 0.13.0, which works fine for now, but eventually would like to get access to the new version of LibTorch in 0.14.0. I will also be asking about upgrading GLIBC on the HPC system, but this is not likely to happen anytime soon of course. Would appreciate it if anyone had any possible workarounds!

Thank for repoting @rdinnager! just to confirm. Did you set Sys.setenv(PRECXX11ABI=1) so it installs a version that requires a lower glibc version?
