Bug#1014491: python3-torch: import fails: undefined symbol
Hi,
Thanks for the bug report. I'm aware of the break, and other users have reported
this issue some time before:
https://lists.debian.org/debian-ai/2022/06/msg00060.html
The break is due to onnx 1.12 upgrade.
The pytorch version in the new queue works fine with onnx 1.12,
as mentioned in the above mailing list post.
If you would like to continue using pytorch 1.8 for a while,
you may need to pin onnx to the previous version, or rollback
using our snapshot archive.
When dealing with the pytorch 1.12 upgrade, I lost
(to be honest I would like to stick to 1.8 but we have to
go through python 3.10 transition)
access to build machines due to complicated reasons, and
the access will not be recovered.
So in order to continue the pytorch upgrade, I have to
upload reverse dependencies to unstable early, so that
I can build pytorch and upload to the NEW queue.
Theoretically this bug can only be resolved when pytorch 1.12
passes the new queue.
