Problem when running on Archlinux tensorflow-opt-cuda #2

Closed p-h closed 1 year ago

p-h commented 6 years ago

I tried running it on libtensorflow.so from this package (version: 1.8.0-5) and it froze my entire computer. The sha224sum of the file is 8f665acf0f455d5056014dfa2d48c22ab6cf83eb073842e8304878d0

I think this is due to #90. As the lib has an insane size around 1GB, OOM simply caused the computer to freeze.

With the fix from #173 applied, it reads totally fine for me:

$ elfx86exts libtensorflow.so.2.13.0
