Знакомство с библиотекой NumPy в Python Что такое NumPy? NumPy (Numerical Python) - это популярная библиотека для вычислительных операций с многомерными массивами и матрицами, а также для выполнения высокоуровневых математических функций. Она предоставляет эффективные инструменты для работы с большими объемами данных и позволяет выполнять различные операции, такие как суммирование, умножение, индексацию и многое другое, без необходимости явно создавать циклы. Преимущества NumPy: - Производительность: NumPy выполняет операции над массивами быстрее, чем стандартные структуры данных Python. - Удобство: NumPy предоставляет удобные методы для работы с данными, такие как срезы, индексация и броадкастинг. - Интеграция: Библиотека интегрируется легко с другими библиотеками, такими как SciPy, pandas и Matplotlib, что делает ее мощным инструментом для научных вычислений. Пример использования NumPy: import numpy as np # Создаем одномерный массив arr = np.array([1, 2, 3, 4, 5]) # Выполняем операции над массивом arr_squared = arr ** 2 arr_sum = np.sum(arr) print("Исходный массив:", arr) print("Квадраты элементов:", arr_squared) print("Сумма элементов:", arr_sum) NumPy также предоставляет функции для работы с многомерными массивами, линейной алгеброй, случайными числами и многое другое. #python#NumPy#научныевычисления#анализданных

#python#evaluation_framework#evaluation_metrics#llm_evaluation#llm_evaluation_framework#llm_evaluation_metrics DeepEval is an open-source tool that makes it easy to test and improve large language model (LLM) applications, much like how Pytest works for regular software, but focused on LLM outputs. It offers over 30 ready-to-use metrics—such as answer relevancy, faithfulness, and hallucination—to check if your LLM is accurate, safe, and reliable. You can test your whole application or just parts of it, and even generate synthetic data for better testing. DeepEval works locally or in the cloud, letting you compare results, share reports, and keep improving your models. This helps you build better, safer, and more trustworthy LLM apps with less effort[1][2][3]. https://github.com/confident-ai/deepeval
