version `GLIBC_2.28' not found

Question

I'm trying to install PyTorch on ARMv7(32-bit) architecture but PyTorch doesn’t have official ARMv7 builds so i tried this unofficial build.

It installed successfully but when I import torch I get the following error

>>import torch
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.7/site-packages/torch/__init__.py", line 81, in <module>
    from torch._C import *
ImportError: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.28' not found (required by /usr/local/lib/python3.7/site-packages/torch/lib/libtorch_python.so)

I tried the following

sudo apt-get update
sudo apt-get install libc6

but it seams like that i have the newest version of libc6

libc6 is already the newest version (2.23-0ubuntu11).
The following packages were automatically installed and are no longer required:
  busybox-initramfs cpio initramfs-tools initramfs-tools-bin initramfs-tools-core klibc-utils libdbusmenu-gtk4 libklibc
  libllvm3.8 libmircommon5 linux-base
Use 'sudo apt autoremove' to remove them.

Here is my GLIBCXX and GLIBC versions that i have:

So is it possible to install GLIBC_2.28 on my machine?

Answer 1

So is it possible to install GLIBC_2.28 on my machine?

It is possible, but the chances of you making a mistake and rendering your system un-bootable are quite high. It is also very likely that doing so will break something else on your system (this is the reason distributions do not usually update the version of GLIBC from the one they originally shipped with).

A much better solution is to built PyTorch targeting your system (i.e. using your "normal" toolchain).

P.S. GLIBCXX has nothing to do with your problem, and just adds noise to your question.

Answer 2

I saw the same problem trying to run Node.js 18 on Ubuntu 18 LTS. I read a lot about the nasty risks of trying to upgrade GLIBC, so in the end I opted for the safe (albeit overkill) option of upgrading to Ubuntu 20 LTS. Problem solved.
