Seperti Textual Inversion, DreamBooth, dan LoRA, Custom Diffusion hanya membutuhkan beberapa (~4-5) gambar contoh. Teknik ini bekerja dengan hanya melatih bobot pada lapisan cross-attention, dan menggunakan kata khusus untuk merepresentasikan konsep yang baru dipelajari. Custom Diffusion unik karena juga dapat mempelajari beberapa konsep secara bersamaan.</p> <p>Jika Anda melatih pada GPU dengan vRAM terbatas, Anda sebaiknya mencoba mengaktifkan xFormers dengan <code>--enable_xformers_memory_efficient_attention</code> untuk pelatihan yang lebih cepat dengan kebutuhan vRAM yang lebih rendah (16GB). Untuk menghemat lebih banyak memori, tambahkan <code>--set_grads_to_none</code> pada argumen pelatihan untuk mengatur gradien menjadi <code>None</code> alih-alih nol (opsi ini dapat menyebabkan beberapa masalah, jadi jika Anda mengalaminya, coba hapus parameter ini).</p> <p>Panduan ini akan membahas skrip <a href="https://github.com/huggingface/diffusers/blob/main/examples/custom_diffusion/train_custom_diffusion.py" rel="nofollow">train_custom_diffusion.py</a> untuk membantu Anda lebih mengenalnya, serta bagaimana Anda dapat menyesuaikannya untuk kebutuhan Anda sendiri.</p> <p>Sebelum menjalankan skrip, pastikan Anda menginstal pustaka dari sumber:</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> Disalin</div><!----></button><!----></div> <pre class="language-bash "><!---->git <span class="hljs-built_in">clone</span> https://github.com/huggingface/diffusers
