What's the maximum lifetime of a colab VM if it is left running with the browser window open (and tensorflow running)?
Ignore this redundant sentence I created because stackoverflow thinks my question is too short!
回答1:
The maximum lifetime of a VM is 12 hours.
Idle VMs time out after 90m. (As you point out, leaving a window open and running a code cell is considered active.)
