It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Bytearray Operations. The optional source parameter can be used to initialize the array in a few different ways: If it is a string,...
Return a new array of bytes. The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Bytearray Operat...

方法/步骤 1 让我们来到一个场景中：我们有一个名为Saliency的灰度图像数组，用来表示一张图片中受关注程度的不同。为了增强可视化效果，我们需要过滤掉数组中数值过小的元素，让其等于0，于是我们可以这么做 2 简单写，可以写作saliency[saliency < 0.0001] = 0# other operations ...3 我们来看看saliency < 0...

autoray is a lightweight python AUTOmatic-arRAY library for abstracting your tensor operations. Primarily it provides an automatic dispatch mechanism that means you can write backend agnostic code that works for: numpy pytorch jax cupy dask autograd tensorflow sparse paddle mars ... and indeed any ...
