return numpy_arrayI omitted type information and other details from these samples, but the difference should be clear. The actual iteration over the NumPy array should be done entirely in Cython, not through repeated calls to Cython for each element in the array.Pass properly typed NumPy arrays ...

循环神经网络,然后hui用Theano(一个可以在GPU上进行运算的库)对实现进行优化。我会跳过一些对理解循环神经网络不是很重要的代码片段,但完整的代码可以在这里找到。 语言模型 这里的目标是用RNN构建一个语言模型,下面会解释一下什么是语言模型。假设有一个包含 ...
一、从已有的序列创建 创建数组最简单的办法是array函数。它接收一切序列型的对象(包括其他数组),然后产生一个新的ndarray对象。【例1】 如果没有说明,array()会尝试为新建的这个数组推断出一个较为合适的数据类型。 np.array(["a", "b", "c"])&nb... ...
