The previous section introduced the concept of game engines and their role in game development. At the same time, the working methods behind the game engine are also mentioned. At the code level, the game engine is a set of encapsulated implementations of underlying graphics, audio, and operating system interfaces. On this basis, an example […]

3-1 Low-level API demonstration
The following example uses Pytorch’s low-level API to implement a linear regression model and a DNN binary classification model. The low-level API mainly includes tensor operations, calculation graphs and automatic differentiation. The implementation of linear models and simple DNN two-classification models is very simple, but it is the most basic part of constructing data, building […]
spring5.3 9: Low-level analysis of circular dependencies
Underlying analysis of circular dependencies What are circular dependencies? It’s very simple, that is, object A depends on object B, and object B depends on object A. //A depends on B class A{<!– –> public B b; } // B depends on A class B{<!– –> public A a; } In Spring, an object is […]
SCSI series ten: low-level driver
The source directory for the SCSI subsystem in the Linux kernel is a good place to start: /usr/src/linux/drivers/scsi. Some drivers include information in a “readme” file: README.. Others have a ton of information at the top of their “.c” files. This information typically includes version numbers, changelogs, and options for kernel boot time and module […]
Very low-level performance optimization: let the CPU execute your code faster
Article directory The impact of cache on performance Improve data cache (dcache) hit rate 1. The reason for faster speed 2. The reason for the 8 times difference in speed Improve instruction cache (icache) hit rate Improve the cache hit rate under multi-core CPU Summarize The impact of Cache on performance First of all, we […]
TensorFlow high-level API and low-level API
TensorFlow provides many APIs, which can be simply classified into high-level APIs and low-level APIs. Too many APIs are too messy and one of the key points of criticism of TensorFlow is that Google has too many engineers and the community is too active. ~ Of course, Google also realized this problem later, and it […]
[Solved] Remember low-level errors – mmdet-centernet
mmdet trains and tests centernet, often uses the framework, but does not study the details of the parameters inside, and serious low-level errors occur. train and test pipline code train_pipeline = [ dict(type=’LoadImageFromFile’, to_float32=True, color_type=’color’), dict(type=’LoadAnnotations’, with_bbox=True), dict( type=’RandomCenterCropPad’, crop_size=(512, 512), ratios=(0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3), mean=[0, 0, 0], std=[1, 1, 1], […]
[Solved] Use nvm to install multiple nodejs versions on win10 system to solve the problem of running low-level front-end projects
I. Reason analysis The nodejs installed on my computer is 16.14.0 It is not the latest, but when running a vue2 project 2 years ago, the project uses vue-admin-template The template, but it can’t run, and the following error is reported: node sass does not yet support your current environment windows 64-bit with unsupported runtime […]
[Solved] router-view does not render (a very low-level error)
A problem encountered in writing code today, router-view does not render. I checked it carefully, and I couldn’t see the problem. I watched it carefully for a long time. In the end, it turned out that it was a spelling mistake. In addition, I saw other centralized reasons on the Internet, which may lead to […]
