<span>النموذج</span></h2> <p data-svelte-h="svelte-f32xk1">الخطوة التالية هي إنشاء <a href="main_classes/models">نموذج</a>. النموذج - ويُشار إليه أحيانًا باسم البنية - يُحدد وظيفة كل طبقة والعمليات الحسابية المُنفذة. تُستخدم خصائص مثل <code>num_hidden_layers</code> من التكوين لتحديد هذه البنية. تشترك جميع النماذج في فئة أساسية واحدة هي <code>PreTrainedModel</code> وبعض الوظائف المُشتركة مثل غيير حجم مُدخلات الكلمات وتقليص رؤوس آلية الانتباه الذاتي. بالإضافة إلى ذلك، فإن جميع النماذج هي فئات فرعية إما من <a href="https://pytorch.org/docs/stable/generated/torch.nn.Module.html" rel="nofollow"><code>torch.nn.Module</code></a>، <a href="https://www.tensorflow.org/api_docs/python/tf/keras/Model" rel="nofollow"><code>tf.keras.Model</code></a> أو <a
