Web13 mrt. 2024 · However, based on common usage in deep learning frameworks such as PyTorch, TensorFlow, and Keras, I can offer some general explanations: In these frameworks, a `net` object usually refers to a neural network model, which consists of multiple layers or modules that transform input data into output predictions. gather keras.backend.gather(reference, indices) 在张量 reference 中检索索引 indices 的元素。参数. reference: 一个张量。 indices: 索引的整数张量。返回. 与 reference 类型相同的张量。 Numpy 实现. def gather(reference, indices): return reference[indices] Meer weergeven 设置变量手动初始化的标志。这个布尔标志决定了变量是否应该在实例化时初始化（默认），或者用户是否应该自己处理初始化（例如通过 tf.initialize_all_variables()）。参数 1. value: Python … Meer weergeven 创建一个常数张量。参数 1. value: 一个常数值（或列表） 2. dtype: 结果张量的元素类型。 3. shape: 可选的结果张量的尺寸。 4. name: 可选 … Meer weergeven 返回学习阶段的标志。学习阶段标志是一个布尔张量（0 = test，1 = train），它作为输入传递给任何的 Keras 函数，以在训练和测试时执行不同的行为操作。返回学习阶段 (标量整数张量或 python 整数)。 Meer weergeven 实例化一个变量并返回它。参数 1. value: Numpy 数组，张量的初始值。 2. dtype: 张量类型。 3. name: 张量的可选名称字符串。 4. constraint: 在优化器更新后应用于变量的可选投影 … Meer weergeven Web6 aug. 2024 · Keras is a model-level library, providing high-level building blocks for developing deep learning models. It does not handle itself low-level operations such as tensor products, convolutions and so on. Instead, it relies on a specialized, well-optimized tensor manipulation library to do so, serving as the “backend engine” of Keras. nicole and orlando
