NumPy是一个广泛适用的Python数据处理库,pandas, OpenCV等库都基于numpy。同时,在PyTorch、TensorFlow、Keras等深度许欸小框架中,了解numpy将显著提高数据共享和处理能力,甚至无需过多更改就可以在GPU运行计算。 n维数组是NumPy的核心概念,这样的好处,尽管一维和而为数组的处理方式有些差异,但多数不同维数组的操作是一...
In fact, this library is the basis of a large amount of mathematical and scientific Python packages, and among them, as you will see later in the book, the pandas library. This library, specialized for data analysis, is fully developed using the concepts introduced by NumPy. In fact, the...
我们首先来了解下如何安装和搭建 Python 语言环境 Python 版本的选择 当前流行的 Python 版本有两个,2.X 和 3.X,由于 2.X 即将不再维护,所以我建议直接使用 3.X 版本作为你的主要版本。 IDE的选择 目前市面上流行着很多的 Python 编辑器,比如 Sublime,Notebook++ 等,不过我还是推荐如下两个 ...
