Elas estão listadas aqui para que você as tenha em mente antes de seguir o <a href="./quickstart">quickstart</a>.</p> <ul><li><strong>O carregamento é preguiçoso e flexível.</strong> <a href="/docs/diffusers/main/pt/api/modular_diffusers/pipeline#diffusers.ModularPipeline.from_pretrained">from_pretrained()</a> monta o pipeline a partir do <code>modular_model_index.json</code> do repositório sem carregar nenhum peso. <a href="/docs/diffusers/main/pt/api/modular_diffusers/pipeline#diffusers.ModularPipeline.load_components">load_components()</a> então os carrega, e não precisa ser tudo de uma vez: por padrão, carrega tudo, mas você pode carregar apenas os componentes que nomear com <code>names</code>, ou o conjunto que um workflow precisa com <code>workflow</code>. <a href="/docs/diffusers/main/pt/api/modular_diffusers/pipeline#diffusers.ModularPipeline.update_components">update_components()</a> permite reutilizar um componente que você já possui, ou um que difere da especificação do repositório. Veja <a href="./modular_pipeline#loading-components">Carregando componentes</a> e <a href="./modular_pipeline#updating-components">Atualizando componentes</a>.</li> <li><strong><a href="/docs/diffusers/main/pt/api/modular_diffusers/pipeline#diffusers.ModularPipeline">ModularPipeline</a> lê um índice diferente, <code>modular_model_index.json</code></strong>, mas também funciona com um repositório que possui apenas um <code>model_index.json</code>, desde que o modelo tenha um pipeline modular. O inverso não é verdadeiro: <a href="/docs/diffusers/main/pt/api/pipelines/overview#diffusers.DiffusionPipeline">DiffusionPipeline</a> e as classes <code>AutoPipeline</code> não funcionam com um repositório que possui apenas um <code>modular_model_index.json</code>.</li> <li><strong>Uma chamada retorna o estado do pipeline</strong>, que também armazena os valores intermediários (<code>prompt_embeds</code>, <code>latents</code>, …). Solicite o que você precisa com o argumento <code>output</code>, <code>output="images"</code> ou <code>output=["images", "latents"]</code>, ou leia um atributo do estado, como no <a href="./quickstart#run-a-pipeline">quickstart</a>. Veja <a href="./modular_diffusers_states">States</a>.</li> <li><strong>O Classifier-free guidance é suportado no componente <code>guider</code></strong>, e não como argumento de chamada de <code>guidance_scale</code>: <code>pipe.update_components(guider=ClassifierFreeGuidance(guidance_scale=5.0))</code>. Consulte o <a href="../using-diffusers/guiders">guia de guiders</a>.</li> <li><strong>Não existe <code>callback_on_step_end</code></strong>; no entanto, você pode inserir um bloco no loop de desruidamento para usar suas funções de callback existentes. Consulte <a href="../using-diffusers/callback#modular-pipelines">Pipelines modulares</a> no guia de callbacks.</li> <li><strong>O pipeline é um grafo de blocos</strong> que você pode modificar (remover, inserir, substituir) antes de construí-lo com <a href="/docs/diffusers/main/pt/api/modular_diffusers/pipeline_blocks#diffusers.ModularPipelineBlocks.init_pipeline">init_pipeline()</a>; <code>pipe.blocks</code> retorna uma cópia, então edite os blocos primeiro. Consulte <a href="./quickstart#compose-new-workflows">Compor novos fluxos de trabalho</a>.</li> <li><strong>O offloading é tratado por um <a href="/docs/diffusers/main/pt/api/modular_diffusers/pipeline_components#diffusers.ComponentsManager">ComponentsManager</a></strong>, que pode atender a vários pipelines que compartilham componentes. Consulte o <a href="./components_manager#offloading">guia do ComponentsManager</a>.</li></ul> <a class="!text-gray-400 !no-underline text-sm flex items-center not-prose mt-4" href="https://github.com/huggingface/diffusers/blob/main/docs/source/en/modular_diffusers/coming_from_diffusion_pipeline.md" target="_blank"><svg class="mr-1" 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="M31,16l-7,7l-1.41-1.41L28.17,16l-5.58-5.59L24,9l7,7z"></path><path d="M1,16l7-7l1.41,1.41L3.83,16l5.58,5.59L8,23l-7-7z"></path><path d="M12.419,25.484L17.639,6.552l1.932,0.518L14.351,26.002z"></path></svg><!----> <span><span class="underline">Update</span> on GitHub</span></a><!----> <p></p><!--]--><!----><!--]--><!--]--><!--]--> <!--[-1--><!--]--><!--]-->
