google tensorflow DOWNGRADE

Affected: 2.18.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.18.0

1. Check installed version

apt-cache policy tensorflow || rpm -q tensorflow || tensorflow --version

2. No fixed release: DOWNGRADE to a release before 2.18.0 (Debian / Ubuntu)

apt-cache madison tensorflow sudo apt install tensorflow=<VERSION_BEFORE_2.18.0> sudo apt-mark hold tensorflow

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list tensorflow sudo dnf downgrade tensorflow-<VERSION_BEFORE_2.18.0> sudo dnf versionlock add tensorflow

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
