Префикс <code>out_</code> был добавлен автоматически, так как вход и выход имеют одинаковое имя (<code>prompt</code>), что позволяет избежать конфликтов имён в конфигурации.

Компоненты модели отсутствуют, а выходные данные включают <code>out_prompt</code>, <code>old_prompt</code> и <code>doc</code>.</p> <p>Теперь рассмотрим словарь <code>params</code>:</p> <ul><li><p><strong><code>prompt</code></strong>: входной параметр с <code>display: "textarea"</code> (отображается как текстовое поле), <code>label: "Prompt"</code> (показывается в интерфейсе) и <code>default: ""</code> (начинается пустым). Поле <code>type: "string"</code> важно в Mellon, поскольку оно определяет, какие узлы можно соединять между собой — связывать «нудлами» можно только узлы с совпадающими типами.</p></li> <li><p><strong><code>out_prompt</code></strong>: Развёрнутый вывод промпта. Префикс <code>out_</code> был добавлен автоматически, так как вход и выход имеют одинаковое имя (<code>prompt</code>), что позволяет избежать конфликтов имён в конфигурации. У него указано <code>display: "output"</code>, что отображается как выходной сокет.</p></li> <li><p><strong><code>old_prompt</code></strong>: имеет <code>type: "custom"</code>, так как мы не указали метаданные. В интерфейсе это отображается как простая точка. Поскольку мы не хотим выставлять это в интерфейсе, мы можем удалить его.</p></li> <li><p><strong><code>doc</code></strong>: Вывод документации, автоматически добавляемый во все пользовательские блоки.</p></li></ul> <!--[2--><h3 class="relative group"><a id="making-adjustments" class="header-link block pr-1.5 text-lg no-hover:hidden with-hover:absolute with-hover:p-1.5 with-hover:opacity-0 with-hover:group-hover:opacity-100 with-hover:right-full" href="#making-adjustments"><span><svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" aria-hidden="true" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 256 256"><path d="M167.594 88.393a8.001 8.001 0 0 1 0 11.314l-67.882 67.882a8 8 0 1 1-11.314-11.315l67.882-67.881a8.003 8.003 0 0 1 11.314 0zm-28.287 84.86l-28.284 28.284a40 40 0 0 1-56.567-56.567l28.284-28.284a8 8 0 0 0-11.315-11.315l-28.284 28.284a56 56 0 0 0 79.196 79.197l28.285-28.285a8 8 0 1 0-11.315-11.314zM212.852 43.14a56.002 56.002 0 0 0-79.196 0l-28.284 28.284a8 8 0 1 0 11.314 11.314l28.284-28.284a40 40 0 0 1 56.568 56.567l-28.285 28.285a8 8 0 0 0 11.315 11.314l28.284-28.284a56.065 56.065 0 0 0 0-79.196z" fill="currentColor"></path></svg><!----></span></a> <span><!---->Внесение изменений<!----></span></h3><!--]--><!----> <p>Уберите <code>old_prompt</code> из <code>params</code> и <code>output_names</code>, так как он больше не понадобится.</p> <div class="code-block relative "><div class="absolute top-2.5 right-4"><button class="inline-flex items-center relative text-sm focus:text-green-500 cursor-pointer focus:outline-none transition duration-200 ease-in-out opacity-0 mx-0.5 text-gray-600 " title="code excerpt" type="button"><svg xmlns="http://www.w3.org/2000/svg" aria-hidden="true" fill="currentColor" focusable="false" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 32 32"><path d="M28,10V28H10V10H28m0-2H10a2,2,0,0,0-2,2V28a2,2,0,0,0,2,2H28a2,2,0,0,0,2-2V10a2,2,0,0,0-2-2Z" transform="translate(0)"></path><path d="M4,18H2V4A2,2,0,0,1,4,2H18V4H4Z" transform="translate(0)"></path><rect fill="none" width="32" height="32"></rect></svg><!----> <div class=" absolute pointer-events-none transition-opacity bg-black text-white py-1 px-2 leading-tight rounded font-normal shadow left-1/2 top-full transform -translate-x-1/2 translate-y-2 opacity-0 "><div class="absolute bottom-full left-1/2 transform -translate-x-1/2 w-0 h-0 border-black border-4 border-t-0" style="border-left-color: transparent; border-right-color: transparent;"></div> Скопировано</div><!----></button><!----></div> <pre class="language-json "><!----><span class="hljs-punctuation">{</span>
