example, if you are deploying a model on devices where inference is constrained (such as mobile and embedded devices), or expensive (cloud servers), it might be worth paying attention to inference efficiency Having such a toolbox to make our models pareto-optimal has the following benefits: Sustainable Server-Side Scaling Training and deploying large deep learning models is costly. While training is a one-time inference can be run completely on the user’s device without the need to send the input data to the server-side. New Applications Efficiency would also enable applications that couldn’t have otherwise been

represented on the y-axis. Refer to Figure 4-1 for the plot. Figure 4-1: A plot of animals being embedded in a two-dimensional space, using ‘cute’ and ‘dangerous’ as the features, based on Table 4-1. The int_sequences_input = tf.keras.Input(shape=(None,), dtype='int64') embedded_sequences = embedding_layer(int_sequences_input) x = tf.reduce_mean(embedded_sequences, axis=1) x = tf.keras.layers.Dense(512, activation='relu')(x) get_cnn_model(embedding_layer): int_sequences_input = tf.keras.Input(shape=(None,), dtype="int64") embedded_sequences = embedding_layer(int_sequences_input) # Run a convolutional layer on top of the sequences

RFECV(estimator, scoring=“r2”) 封装式（Wrap- per），结合交叉验证的递归特征消除法，自动选择最优特征个数 fs.SelectFromModel(estimator) 嵌入式（Embedded），从 模型中自动选择特征，任何具有coef_或者 feature_importances_的 基模型都可以作为estimator参数传入 14 2.Scikit-learn主要用法 监督学习算法-回归

channels. Libraries like XNNPACK3,4 can help accelerate networks on a variety of web, mobile, and embedded devices, provided the user can design networks that match their constraints. One might wonder what

the words “embeddings” and “vectors” interchangeably in the text. Embeddings is a term for vectors embedded in the vocabulary space such that related words lie close to each other. # Initialize a representation

Input(shape=(100,), dtype='int32') embedded_question = Embedding(input_dim=10000, output_dim=256, input_length=100)(question_input) encoded_question = LSTM(256)(embedded_question) 快速开始 25 # 连接问题向量和图像向量：

install vllm 运行以下代码以构建 vllm 服务。此处我们以 Qwen1.5-7B-Chat 为例： python -m vllm.entrypoints.openai.api_server --model Qwen/Qwen1.5-7B-Chat 然后，您可以使用 create chat interface 来与 Qwen 进行交流： curl http://localhos 包中的 Python 客户端： from openai import OpenAI # Set OpenAI's API key and API base to use vLLM's API server. openai_api_key = "EMPTY" openai_api_base = "http://localhost:8000/v1" client = OpenAI( (续下页) safetensor.index.json │ │ ├── merges.txt │ │ ├── tokenizer_config.json │ │ └── vocab.json 随后你需要运行 python server.py 来启动你的网页服务。请点击进入 `http://localhost:7860/?__theme=dark` 然后享受使用 Qwen 的 Web UI 吧！ 1.6.2 下一步 TGW
