爲什麼需要swap?
在我使用TENSORFLOW期間，我發現我16GB內存不夠用，交換 內存可以將存儲空間的一部分用於內存使用。該方法在jetson xavier上實測有效。
在ubuntu上安全快速的創建永久的交換分區（SWAP）方法
開始
-
-$ df -h
This will show your file system and how much space you have left.
-
-$ sudo fallocate -l 8.0G /swapfile
Create a 8 GB of swap
-
-$ sudo chmod 600 /swapfile
Change file permissions
-
-$ sudo mkswap /swapfile
-
-$ sudo swapon /swapfile
-
-$ free -m
This will show you the swap file is on. You can also pull up the System Monitor
However this is only temporary. If you reboot, swap file is gone.
-
-$ sudo nano /etc/fstab
-
Within this file add the line “/swapfile none swap 0 0”. Do not include the quotes.
Exit and save file
-
Now you can reboot and your Swap will be activated.
-
Then you can successfully train the CIFAR-10 dataset.
Ideally you would want to create a swap partition on an attached SSD or M.2 SSD and not use any of the internal memory.
