再者,在科学领域,特别是在机器学习、数据科学领域,
Python
也被
大量使用。
Python
除了高性能之外,凭借着
NumPy
SciPy
等优秀的数
值计算、统计分析库,在数据科学领域占有不可动摇的地位。深度学习的
框架中也有很多使用
Python
的场景,比如
Caffe
TensorFlow
Chainer
Theano
等著名的深度学习框架都提供了
Python
接口。因此,学习
Python
对使用深度学习框架大有益处。
综上,
Python
是最适合数据科学领域的编程语言。而且,
Python
具有
受众广的优秀品质,从初学者到专业人士都在使用。因此,为了完成本书的
从零开始实现深度学习的目标,
Python
可以说是最合适的工具。

Python
时,需要慎重选择安装
Python
的哪个版
