AI入门第1课：把模型跑起来


    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">AI大模型发展到<span style="color: black;">此刻</span>，国内外都有在线和离线版本，那<span style="color: black;">怎样</span>在自己本地<span style="color: black;">安排</span>大模型呢？本文分享了一种简单的办法，<span style="color: black;">一块</span>来<span style="color: black;">瞧瞧</span>吧。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-axegupay5k/228c22966670436ba924904a52738609~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1727526496&amp;x-signature=BUi%2FAnO%2BsCBgSCJhM0qyQdTCiic%3D" style="width: 50%; margin-bottom: 20px;">
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>经常能看到某某<span style="color: black;">机构</span>开源了一款AI大模型的<span style="color: black;">资讯</span>。这些模型都有着超强的能力，从生成大段的文字、逼真的图像，到理解和翻译<span style="color: black;">区别</span>语言，再到创造出令人叹为观止的音乐和艺术作品。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">针对</span><span style="color: black;">咱们</span>普通人<span style="color: black;">来讲</span>，这些高科技听起来不仅遥不可及，<span style="color: black;">况且</span>似乎与<span style="color: black;">咱们</span>的<span style="color: black;">平常</span>生活无关，<span style="color: black;">她们</span>像是<span style="color: black;">仅有</span><span style="color: black;">哪些</span>天才和大神们<span style="color: black;">才可</span>操作和<span style="color: black;">运用</span>的。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">然则</span>这些强大的AI模型，并不止是大神们<span style="color: black;">才可</span>接触和<span style="color: black;">运用</span>，<span style="color: black;">实质</span>上，这些模型的<span style="color: black;">运用</span>门槛<span style="color: black;">并不</span>高。任何对AI感兴趣的人都<span style="color: black;">能够</span><span style="color: black;">容易</span>获取和<span style="color: black;">运用</span>这些模型，就像搭乐高积木<span style="color: black;">同样</span>，将它们组合起来，创造出你心目中的应用。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这一切既不需要深厚的技术背景，<span style="color: black;">亦</span>不需要<span style="color: black;">繁杂</span>的编程技能。<strong style="color: blue;">只要你有想法和一丢丢的学习</strong>，这些强大的模型就能<span style="color: black;">作为</span>你随意操作的「乐高」，搭建出你设想的样子。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">下面<span style="color: black;">咱们</span><span style="color: black;">一块</span>来看下，<strong style="color: blue;"><span style="color: black;">怎样</span>把模型跑起来</strong>～</p>
    <h1 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">第1</span>步：找到一个模型</h1>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">首要</span>，<span style="color: black;">第1</span>步<span style="color: black;">咱们</span>得<span style="color: black;">晓得</span>去哪里找到这些模型，很简单，有一个神奇的网站叫：Hugging Face（https://huggingface.co/），这个网站本质<span style="color: black;">便是</span>一个大模型的托管网站，<span style="color: black;">日前</span>这个网站托管的AI模型超过57万。<span style="color: black;">有些</span>热门的模型，<span style="color: black;">例如</span>meta的Llama系列模型，google的Gemini等都托管在这个网站上，任何人都<span style="color: black;">能够</span><span style="color: black;">拜访</span>并<span style="color: black;">运用</span>它们。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/8775218cedbbcfefe49a2fb5975569ad~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1727526496&amp;x-signature=jk60th%2B%2BNBif9C%2B8oG2LnA6c66Y%3D" style="width: 50%; margin-bottom: 20px;">
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">假设，<span style="color: black;">咱们</span><span style="color: black;">此刻</span>要找一个模型，<span style="color: black;">能够</span>实现读图的功能，<span style="color: black;">便是</span>给它一张<span style="color: black;">照片</span>，它<span style="color: black;">能够</span>告诉我这个<span style="color: black;">照片</span>里的<span style="color: black;">重点</span>内容是什么。这个模型的<span style="color: black;">规律</span>如下图，非常简单，输入一张<span style="color: black;">照片</span>，输出一段<span style="color: black;">照片</span>的文本描述。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/e1009bf13657cffea23aaff0bb0cf76f~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1727526496&amp;x-signature=DQQyBnEfv3IU274jfm%2Bes3FIkMM%3D" style="width: 50%; margin-bottom: 20px;">
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这个模型本质上<span style="color: black;">便是</span>一个<span style="color: black;">照片</span>到文本的模型，<span style="color: black;">咱们</span>在Hugging Face里<span style="color: black;">选取</span>Image-to-Text的<span style="color: black;">归类</span>，<span style="color: black;">而后</span>从得到的结果里看排名<span style="color: black;">第1</span>个的模型，<span style="color: black;">便是</span>下图红框圈选的：</p>Salesforce/blip-image-captioning-large，这个<span style="color: black;">便是</span>模型的名字。
    <img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/fb58550ebd4fbf7d93e6905078065cd4~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1727526496&amp;x-signature=kdCJtdw93NIvuOcaF4Mv70sCZDY%3D" style="width: 50%; margin-bottom: 20px;">
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">点击模型进行模型的详情页，<span style="color: black;">这儿</span>有模型的<span style="color: black;">仔细</span>原理介绍，以及在线试用的功能，<span style="color: black;">能够</span>在<span style="color: black;">这儿</span>直接体验模型的效果。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/5a026443d4c67f8c5ae481694159fae4~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1727526496&amp;x-signature=UKoWm0SyF9oNI2lFRD0JxpKtZpo%3D" style="width: 50%; margin-bottom: 20px;">
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">找到了模型之后，<span style="color: black;">咱们</span>接下来第二步，<span style="color: black;">怎样</span><span style="color: black;">安排</span>和<span style="color: black;">运用</span>模型。</p>
    <h1 style="color: black; text-align: left; margin-bottom: 10px;">第二步：模型的<span style="color: black;">安排</span>和<span style="color: black;">运用</span></h1>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">模型的<span style="color: black;">运用</span><span style="color: black;">触及</span>到模型的加载、预处理、模型推理和后处理<span style="color: black;">过程</span>等，听起来似乎很<span style="color: black;">繁杂</span>，<span style="color: black;">然则</span><span style="color: black;">不消</span>担心，Hugging Face还给<span style="color: black;">咱们</span><span style="color: black;">供给</span>了一套<span style="color: black;">运用</span>的工具，那<span style="color: black;">便是</span>Transformers库中的pipeline<span style="color: black;">办法</span>，pipeline 将前面<span style="color: black;">说到</span>的模型<span style="color: black;">运用</span>所有<span style="color: black;">过程</span>封装成一个简单的函数调用。<span style="color: black;">咱们</span>只需要<span style="color: black;">运用</span>这个函数<span style="color: black;">办法</span>，指定需要完成的任务类型，当然<span style="color: black;">咱们</span><span style="color: black;">亦</span><span style="color: black;">能够</span>指定特定的模型和配置来定制<span style="color: black;">运用</span>。Transformers库<span style="color: black;">是由于</span>Hugging Face<span style="color: black;">机构</span><span style="color: black;">研发</span>的一个开源Python库，里面除了pipeline外，还有<span style="color: black;">非常多</span>其它的<span style="color: black;">办法</span>和工具，<span style="color: black;">这儿</span>就不细说了。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">详细</span>的<span style="color: black;">运用</span>其实<span style="color: black;">便是</span>几行Python代码就<span style="color: black;">能够</span>搞定，非常简单。<span style="color: black;">这儿</span>额外说下，<span style="color: black;">咱们</span>经常在<span style="color: black;">运用</span>写python的时候，需要安装编译器和配置环境，<span style="color: black;">常常</span>这些环境配置就<span style="color: black;">已然</span>消耗了<span style="color: black;">咱们</span>的所有激情了。<span style="color: black;">这儿</span>，感谢google大大<span style="color: black;">供给</span>的一个在线编程工具colab，直接<span style="color: black;">处理</span>所有安装和环境问题。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Colaboratory界面如下，<span style="color: black;">便是</span>一个<span style="color: black;">能够</span>在线写python代码的「笔记本」。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/bd008ff795cf995cfaa2508ca048e283~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1727526496&amp;x-signature=f%2B7hrPbxG1IYzN2vVZbaFi4oaaM%3D" style="width: 50%; margin-bottom: 20px;">
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>新建一个文件，<span style="color: black;">而后</span>输入<span style="color: black;">第1</span>行代码：</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">pip install transformers</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">就<span style="color: black;">这般</span>一行代码，Transformers库就安装好了。后面<span style="color: black;">详细</span>的操作，点击上传<span style="color: black;">照片</span>。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">随后编写的代码和解释如下，懂一点点python和编程的人，应该就能写出来。写完后点击代码侧边的运行按钮<span style="color: black;">就可</span>。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/2bf21a572c8ffbe55235d8d3a73139b4~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1727526496&amp;x-signature=Jh8IcshFBFpYLJlogWBDluejqw4%3D" style="width: 50%; margin-bottom: 20px;">
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">输出的文案是：arafed woman sitting on the ground with a camera and a tripod. （一位戴着头巾的女性坐在地上，旁边放着相机和三脚架。）基本识别出来<span style="color: black;">照片</span>中的<span style="color: black;">重点</span>内容。</p>

真情实感，其含义为认真了、走心了的意思，是如今的饭圈常用语。
