Hello (sighs), I’m unable to find proper versions for cuda enabled pytorch and its matching torchvision. I have tried multiple links, forum guides etc but all of them leads to some version mismatch errors in the end. Can someone pls help me biuld correct and latest working versions? (If u had trie…

Oh my goodness… I wasted 20+ hours trying to resolve all these dependencies in spare time over weeks starting before this thread was born. The @johnny_nv and the one post after for making sure to setup the cudss in that order worked. I may actually be able to run the training code from the Deep L…

I got the same issue on Jetson Orin AGX with Jetpack 6.2. Any solutions? I noticed that torch 2.8.0 in jp6/cu126 index now has different SHA than what I installed like 1-2 months ago. Whay can’t we get consistent setup for Jetson devices. It has been frustrating experience.

As far as I know, there are no solns. There was a solution 1w ago but the files were removed from pypi jetson-ai website. Even I’m waiting for help from many days! :) HELPPPPP!!!

Hi, Please get the libnccl pacakge from (JP6.2: cuda 12.6) https://developer.nvidia.com/nccl/nccl-legacy-download If you encounter the undefined symbol error, please reinstall the torch whl Thanks

I was previously able to successfully install and import Torch using the wheels from https://pypi.jetson-ai-lab.io/jp6/cu126 . However, at some point, after installing Torch, import torch started failing. Could there be a problem with the torch-2.8.0-cp310-cp310-linux_aarch64.whl build?

Hi, We will spend some time to check whether we could reproduce in our side. When download the nccl, we use below commands as download center show sudo apt install libnccl2=2.22.3-1+cuda12.6 libnccl-dev=2.22.3-1+cuda12.6 Thanks

Hmm, with the latest .deb file I downloaded , it had this command: nvidia@nvidia-desktop:~/Downloads$ sudo apt install libnccl2=2.24.3-1+cuda12.6 libnccl-dev=2.24.3-1+cuda12.6 Reading package lists… Done Building dependency tree… Done Reading state information… Done libnccl-dev is already the n…

Hi! I have the same error “undefined symbol: ncclCommWindowDeregister” , and I fix it by re-install the whl, like DavidDDD said. pip3 install torch-2.8.0-cp310-cp310-linux_aarch64.whl --force-reinstall pip3 install torchvision-0.23.0-cp310-cp310-linux_aarch64.whl --force-reinstall Now the error…

I tried this. Still got an error Python 3.10.18 | packaged by conda-forge | (main, Jun 4 2025, 14:39:45) [GCC 13.3.0] on linux Type “help”, “copyright”, “credits” or “license” for more information. import torch Traceback (most recent call last): File “”, line 1, in File “/data/anaconda3/en…

David, I’ve reinstalled the same torch wheel but again ran into same error!? :(

Edit: I had downloaded this: nccl-local-repo-ubuntu2204-2.24.3-cuda12.6_1.0-1_arm64.deb
