If your step is positive, then you move through a series of increasing numbers and are incrementing. If your step is negative, then you move through a series of decreasing numbers and are decrementing. This allows you to go through the numbers backwards. 如果您的step是肯定的,那么您将经历一...
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 ...
In this code, you are creating a 3x3 array arr_1 storing the values from 1 through 9. Then, you create a 2x2 slice of the original array storing from the second value to the end in both dimensions, arr_2. Notice that the Python indexing is 0-based, so the second element has the...
This is for backwards compatibility: the logging package pre-dates newer formatting options such as str.format() and string.Template. if logger.isEnabledFor(logging.DEBUG): logger.debug('Message with %s, %s', expensive_func1(), expensive...

Usually, the frame contents will be held in a contiguous array, and this method will yield n_planes of data chunks each holding the entire plane. Don’t, however, take this for granted, as it can’t be the case, and you will iterate over lines of plane data instead, which are assure...
You can implement nested loops using a while loop inside the for loop. Like for loop, while loop also iterates over the iterable objects such as alist,tuple,set,dictionary,string, andarrayuntil a certain condition is met. Below example, we will iterate the given list using an outer loop....
