对n维logit张量的第n维执行softmax。对于二维logits,这可以归结为tf.n .softmax。第n个维度需要具有指定数量的元素(类的数量)。
本文介绍了在使用TensorFlow时,使用tfrecords文件时的注意事项。包括确保字符串输入生成器中的文件名正确,在解码tfrecords时确保类型一致,以及如何处理非浮点数类型等问题。如果遇到问题,应该检查是否正确使用了float32类型,以及是否有文件名错误等。
fetches from the region of linear memory bound to the one-dimensional texture reference texRef using integer texture coordinate x. tex1Dfetch() only works with non-normalized coordinates, so only the border and clamp addressing modes are supported. It does not perform any texture filtering. For integer types, it may optionally promote the integer to single-precision floating point.

3.2.11.1.3. 16-Bit Floating-Point Textures The 16-bit floating-point or half format supported by CUDA arrays is the same as the IEEE 754-2008 binary2 format. CUDA C does not support a matching data type, but provides intrinsic functions【内联函数】 to convert

Overflow usually makes your numeric algorithm meaningless. Incrementing a value beyond a maximum value can lead to memory corruption and undefined behavior.
我们正带领大家开始阅读英文的《CUDA C Programming Guide》,今天是第15天,我们用几天时间来学习CUDA 的编程接口,其中最重要的部分就是CUDA C runtime.希望在接下来的85天里,您可以学习到原汁原味的CUDA,同时能养成英文阅读的习惯。 本文共计976字,阅读时间20分钟 今天开始要花几天时间讲解Texture and Surface Memory 3.2.11. Texture and Surface Memory CUDA supports a subset o
如果说 C++11 和 C++20 是两个改动大、影响比较深远的"大版本",那么我感觉 C++17 算是一个小版本。(推荐 vs2019,gcc8,clang10,支持 C++17)
TypeScript 是一种由微软开发的自由和开源的编程语言。它是 JavaScript 的一个超集,而且本质上向这个语言添加了可选的静态类型和基于类的面向对象编程。TypeScript 提供最新的和不断发展的 JavaScript 特性,包括那些来自 2015 年的 ECMAScript 和未来的提案中的特性,比如异步功能和 Decorators,以帮助建立健壮的组件。
内置函数 max 返回固定数量的 [cmp.Ordered] 类型参数中的最大值。该接口要求至少提供有一个参数。如果 T 是浮点类型,或有任意一个参数是 NaN,那max 将返回 NaN。
The torch package contains data structures for multi-dimensional tensors and mathematical operations over these are defined. Additionally, it provides many utilities for efficient serializing of Tensors and arbitrary types, and other useful utilities.It has a CUDA counterpart, that enables you to run your tensor computations on an NVIDIA GPU with compute capability >= 3.0.
本系列文章将从一些著名开源项目中找一些 TypeScript 代码,讲解如何应用 TypeScript。
It’s rare when a highly structured language with fairly strict syntax sparks emotions of joy and delight. But Kotlin, which is statically typed and compiled like other less friendly languages, delivers a developer experience that thousands of mobile and web programmers are falling in love with. The designers of Kotlin, who have years of experience with developer tooling (IntelliJ and other IDEs), created a language with very specific developer-oriented requirements. They wanted a modern syntax, fast compile times, and advanced concurrency constructs while taking advantage of the robust performance and reliability of the JVM. The result, Kotlin 1.0, was released in February 2016 and its trajectory since then has been remarkable. Google recently announced official support for Kotlin on Android, and many server-side technologies have introduced Kotlin as a feature.
我们首先介绍一下TensorBoard的使用,然后介绍TensorFlow的基本ops,之后介绍张量的数据类型,最后介绍一下如何将自己的输入导入模型。
在安装TensorFlow时,必须要注意与CUDA、cuDNN版本之间的搭配,否则有可能安装失败。下图是windows系统下版本对应关系:
为什么要说ONNX,ONNX又是个什么东西,经常要部署神经网络应用的童鞋们可能会ONNX会比较熟悉,我们可能会在某一任务中将Pytorch或者TensorFlow模型转化为ONNX模型(ONNX模型一般用于中间部署阶段),然后再拿转化后的ONNX模型进而转化为我们使用不同框架部署需要的类型。
1. Distinguish between () and {} when creating objects C++11中,初始化值的指定方式有三种:括号初始化,等号初始化和花括号初始化;其中花括号初始化是为了解决C++98的表达能力而引入的一种统一初始化思想的实例。 等号初始化和花括号初始化可以用于非静态成员变量的初始化 class Widget { ... private: int x {0}; // ok int y = 0; // ok int z(0);
In the last episode we talked about the data representation of integer, a kind of fixed-point numbers. Today we’re going to learn about floating-point numbers.

接下来又认识了免疫组库测序数据,知道了免疫组库测序数据的一些特性,并且使用igblast进行免疫组库分析了,但是那个是初步的比对,虽然找到每一个测序片段的V,D(可选),J,C基因,并且拿到 CDR3序列,中间步骤有点多,常规的测序数据过滤就算了,还需要把PE数据合并,fastq格式转为fasta格式,而且本身igblast软件就很难使用,数据库文件构建也繁琐。其实也有包装好的一站式流程。
如果是运行在在 iOS 5.0 之前或者没有使用 ARC 的情况下, 需要手工调用 release 方法进行回收。
某一天,开发问我,为什么针对一个查询会有两条记录,且其中一条记录并不符合条件select * from tablea where xxno = 170325171202362928;xxno为 170325171202362928 和 170325171202362930的都出现在结果中。

好,言归正传,在GDS中打上自己的logo是一件很cool的事,而且有时候也是很必要的。
A programming language is usually designed with a specific purpose in mind. This purpose can be anything from serving a specific environment (e.g, the web) to a certain paradigm (e.g. functional programming). In the case of Kotlin the goal is to build a productive and pragmatic language, that has all the features that a developer needs and makes easy to use them.
In each case, we save writing a longish, hard-to-remember type that the compiler already knows but a programmer could get wrong.
在 TensorFlow 之中,分布式变量是在多个设备上创建的变量。Mirrored variable 和 SyncOnRead variable 是两个例子。本文就对分布式变量进行分析。我们通过一系列问题来引导分析:

Many language and library facilities rely on default constructors to initialize their elements, e.g. T a[10] and std::vector<T> v(10). A default constructor often simplifies the task of defining a suitable moved-from state for a type that is also copyable.

Computational photography is about enhancing the photographic process with computation. While we normally tend to think that this applies only to post-processing the end result (similar to photo editing), the possibilities are much richer since computation can be enabled at every step of the photographic process—starting with the scene illumination, continuing with the lens, and eventually even at the display of the captured image.
