Libtorch nightly versions

C++
1

Hello,
on https://pytorch.org/get-started/locally/ it says that one should use the download link https://download.pytorch.org/libtorch/nightly/cu128/libtorch-cxx11-abi-shared-with-deps-latest.zip for the latest nightly release of libtorch.
However, the last CXX11 ABI version is from March 20. All newer versions for Linux are published under a file name like libtorch-shared-with-deps-2.8.0.dev20250507%2Bcu128.zip.
Does someone know if the CXX11 ABI variant is discontinued and why it is still recommended on the PyTorch website?

Thanks in advance!

We stopped building binaries with pre-CXX11 ABI so you should be able to download the latest one without the cxx11-abi tag.
We should revisit the install command and fix it. CC @malfet for visibility

Perfect, thanks for the quick reply! The latest version without the cxx-abi tag also works flawlessly for me and has the latest commit from GitHub.

I just wanted to follow up on that. Currently, the URL suggested at https://pytorch.org/get-started/locally/ for installing the latest nightly version of libtorch not only leads to an old version, but is also broken:

https://download.pytorch.org/libtorch/nightly/cu129/libtorch-cxx11-abi-shared-with-deps-latest.zip

It should be changed to the version without “cxx11-abi”:

https://download.pytorch.org/libtorch/nightly/cu129/libtorch-shared-with-deps-latest.zip

Thank you for reporting, let me create an issue and we should fix the links before 2.8.0 release, see Nightly libtorch links on website are incorrect · Issue #159880 · pytorch/pytorch · GitHub
