数据神器NumPy 我们知道，不管是机器学习(MachineLearning,ML)，还是深度学习(DeepLearning,DL)，模型(Model)、算法(algorithm)、网络结构(structure)都可以用现成的，但数据是要自己负责I/O并传递给算法的。而各种算法，实际上处理的都是矩阵和向量。 NumPy由数据科学家TravisOliphant创作，支持维度数组与矩阵运算。结合...

The Python interpreter uses whitespace indentation to determine which pieces of code are grouped together in a special way — for example, as part of a function, loop, or class. How much space is used is not typically important, as long as it is consistent. If two spaces are used to ...
