                    <h2>为什么需要swap?</h2> 
<p>在我使用TENSORFLOW期间&#xff0c;我发现我16GB内存不够用&#xff0c;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。</p> 
<p>在ubuntu上安全快速的创建永久的交换分区&#xff08;SWAP&#xff09;方法</p> 
<h3>开始</h3> 
<ol><li> <p>-$ df -h</p> <p>This will show your file system and how much space you have left.</p> </li><li> <p>-$ sudo fallocate -l 8.0G /swapfile</p> <p>Create a 8 GB of swap</p> </li><li> <p>-$ sudo chmod 600 /swapfile</p> <p>Change file permissions</p> </li><li> <p>-$ sudo mkswap /swapfile</p> </li><li> <p>-$ sudo swapon /swapfile</p> </li><li> <p>-$ free -m</p> <p>This will show you the swap file is on. You can also pull up the System Monitor</p> <p>However this is only temporary. If you reboot, swap file is gone.</p> </li><li> <p>-$ sudo nano /etc/fstab</p> </li><li> <p>Within this file add the line “/swapfile none swap 0 0”. Do not include the quotes.</p> <p>Exit and save file</p> </li><li> <p>Now you can reboot and your Swap will be activated.</p> </li><li> <p>Then you can successfully train the CIFAR-10 dataset.</p> </li></ol> 
<p>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.</p></div></article></div><div class="fzithome-com info"><div><span>本文发布于:2025-03-22，感谢您对本站的认可！</span></div><div><span>本文链接:</span><a href="https://www.fzithome.com/biancheng/1742619089a1768535.html" title="GPU内存不够用怎么办？（5分钟扩充显存到32GB）">https://www.fzithome.com/biancheng/1742619089a1768535.html</a></div><div><span>版权声明:本站内容均来自互联网，仅供演示用，请勿用于商业和其他非法用途。如果侵犯了您的权益请与我们联系，我们将在24小时内删除。</span></div></div><span class="tag"><i class="iconfont icon-discount" style="font-size:12px;font-weight:bold;opacity:.7;">本文标签：</i><a href="/tag/667.html" target="_blank">显存</a><a href="/tag/71418.html" target="_blank">不够用</a><a href="/tag/433.html" target="_blank">内存</a><a href="/tag/68085.html" target="_blank">GPU</a><a href="/tag/70203.html" target="_blank">GB</a></span></div><div class="fzithome-com post_comments" id="comments"><div id="comt-respond" class="commentpost"><h4>发布评论
