为什么需要swap?

在我使用TENSORFLOW期间，我发现我16GB内存不够用，交换 内存可以将存储空间的一部分用于内存使用。该方法在jetson xavier上实测有效。

在ubuntu上安全快速的创建永久的交换分区（SWAP）方法

开始

1. -$ df -h

   This will show your file system and how much space you have left.

2. -$ sudo fallocate -l 8.0G /swapfile

   Create a 8 GB of swap

3. -$ sudo chmod 600 /swapfile

   Change file permissions

4. -$ sudo mkswap /swapfile

5. -$ sudo swapon /swapfile

6. -$ 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.

7. -$ sudo nano /etc/fstab

8. Within this file add the line “/swapfile none swap 0 0”. Do not include the quotes.

   Exit and save file

9. Now you can reboot and your Swap will be activated.

10. 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.
