Я испытываю что-то странное.Когда я запускаю tensorflow program, он выводит эту информацию перед запуском:

Как вы видите, он говорит:
totalMemory: 10.91GiB freeMemory: 10.19GiB
Однако, когда я проверяю, сколько у меня памятикоманда с помощью этой команды:
free -g
Я вижу этот вывод:
total used free shared buff/cache available
Mem: 31 5 24 0 1 25
Swap: 0 0 0
Почему тензор потока не имеет доступа ко всей памяти?Возможно, я что-то пропустил, пожалуйста, дайте мне знать.
