torch.flatten()

先看函数参数：torch.flatten(input, start_dim=0, end_dim=-1)input: 一个 tensor，即要被“推平”的 tensor。 示例代码：x = torch.flatten(t, start_dim=1)print(x, x.shape)y = torch.flatten(t, start_dim=0, end_dim=1)print pytorch中的 torch.nn.Flatten 类和 torch.Tensor.flatten 方法其实都是基于上面的 torch.flatten 函数实现的。

Flatten 实现类型 Flatten: type flatten = Flatten<[1, 2, [3, 4], [[[5]]]]> // [1, 2, 3, 4, 5] 此题一看就需要递归： // 本题答案 type Flatten<T extends any[], Result extends any[] = []> = T extends [infer Start, ...infer Rest Flatten<Rest, [...Result, ...Flatten<Start>]> : Flatten<Rest, [...Result, Start]> ) : Result 这道题看似答案复杂 则直接存进去继续递归，此时 T 自然是剩余的 Rest；如果第一个值是数组，则将其打平，此时有个精彩的地方，即 ...Start 打平后依然可能是数组，比如 [[5]] 就套了两层，能不能想到 ...Flatten 讨论地址是：精读《Permutation, Flatten, Absolute...》· Issue #426 · dt-fe/weekly 如果你想参与讨论，请 点击这里，每周都有新的主题，周末或周一发布

Python——数组重组（flatten

一、numpy.flatten一、numpy.flatten一、numpy.flatten ndarray.flatten(order='C') 将数组变为一维 Parameters: order : {‘C’, ‘F’, ‘A’, ‘K’}, optional ‘C’ means to flatten in row-major (C-style ‘F’ means to flatten in column-major (Fortran- style) order. ‘A’ means to flatten in column-major order if a is Fortran contiguous in memory ‘K’ means to flatten a in the order the elements occur in memory.

numpy: np.ndarray.flatten

Syntax ndarray.flatten(order=’C’) 将numpy数组的返回成 一个维度 。 Args： 顺序：{‘C’，’F’，’A’，’K’}，可选。 Returns： y：ndarray 实验代码 # coding: utf-8 import numpy as np # flatten 只对 np.ndarray 型 矩阵 有效，所以要先转换为 np.ndarray 型 a = np.array([[1, 2], [3, 4]]) # flatten 返回值 也是 np.ndarray 型的 assert isinstance(a.flatten (), np.ndarray) # 通过 list 函数转换 结果 为 列表 assert list(a.flatten()) == [1, 2, 3, 4] # 参数默认值为 order='C' assert list(a.flatten()) == list(a.flatten('C')) assert list(a.flatten('F')) == [1, 3, 2, 4] ---- ---

2019-1-2-使用flatten展开AggregateException

AggregateException的内部也嵌套了AggregateException那么就很尴尬了 我们必须使用while循环进行处理 不过AggregateException提供了一个简单的解决方案，就是Flatten 方法 Flatten方法可以将AggregateException以迭代的方式展开，所有的InnerException,以列表的形式进行单独处理哦(如微软的例子所示) public class Example task1.Wait(); } catch (AggregateException ae) { foreach (var e in ae.Flatten else { throw; } } } } } 参考链接： AggregateException.Flatten Method (System) - Microsoft Docs ---- 本文会经常更新，请阅读原文： https://xinyuehtx.github.io/post/%E4%BD%BF%E7%94%A8flatten

CNN的Flatten操作 | Pytorch系列（七）

在这篇文章中，我们将可视化一个单一灰度图像的张量flatten 操作，我们将展示如何flatten 特定的张量轴，这是CNNs经常需要的，因为我们处理的是批量输入而不是单个输入。 ? 张量的flatten 张量flatten操作是卷积神经网络中的一种常见操作。这是因为传递给全连接层的卷积层的输出必须在全连接层接受输入之前进行flatten。 These axes need to be flattened: (C,H,W) 这可以通过PyTorch的内置flatten() 方法来完成。 三、扁平化张量的特定轴 运行下面的代码： > t.flatten(start_dim=1).shape torch.Size([3, 16]) > t.flatten(start_dim=1) tensor 请注意，这里的start_dim参数告诉flatten() 方法从何处开始展平。在这种情况下，我们将使整个图像变平。

对两个flatten函数的探究

1 问题 对torch.nn.flatten()和torch.flatten()两个函数的理解。 2 方法 对于torch.nn.Flatten()：其默认参数为start_dim = 1 , end_dim = -1，即从第1维（第0维不变）开始到最后一维结束将每个batch拉伸成一维：当仅设置一个参数时 ，该参数表示 start_dim 的值，即从该维度开始到最后一个维度结束，将每个batch拉伸成一维，其余维度不变：当设置两个参数时，两个参数分别表示开始维度和结束维度：Torch.nn.flatten ()函数官方文档：对于torch.flatten()：torch.flatten()函数默认start_dim = 0 , 其余与torch.nn.flatten()相同。 torch.flatten()函数官方文档： 3 结语 通过对照实验，对两个函数的参数进行比照分析，得出结论。
