Linear feedback shift register (LFSR)
In practice, the selection of random seeds determines the difference of pseudo-random sequences, which means the selection of random seeds is very important.
The most common way to generate pseudo-random numbers is to use a linear feedback shift register (LFSR).nA D trigger and several XOR gatesThe following pictures are made:
Where GN is the feedback coefficient, the value can only be 0 or 1, take 0 to show that there is no feedback path, take 1 to show that there is a feedback path; where the feedback coefficient determines the different al...
P1502″ stars
Title Description
In the evening, Ka looked out from the balcony and said, “Wow, lots of stars.” But he didn’t have a window for the other rooms. The naive Ka always wanted to see the brightest stars at night, but the window was fixed in size and the sides had to be parallel to the ground. At that time, the card used superpower (perspective).You know the position and brightness of each star behind the wall, but the little card gets tired after superpowering, so please tell him that there are at most a total number of bright stars that can appear in the wi...
Use in C#Stopwatch
Namespace: System.Diagnostics;
System.Diagnostics.Stopwatch stopwatch = new System.Diagnostics.Stopwatch();
stopwatch.Start();
// Here: Computation time consuming process / method
stopwatch.Stop();
stopwatch.Elapsed.TotalSeconds //Here is the total number of seconds to run, accurate to milliseconds.
On iOS 11, 1. First execute the animation group to execute frame animation in the set picture, 2. Set the picture in the set frame animation, execute frame animation without any problem.
On iOS 10 and iOS 9, you must execute method 2 (first set the picture to set the frame animation, execute the frame animation), otherwise you can’t set the picture after the frame animation.
/// imageViewTo achieve frame animation, the last picture transposition with the right number of open box picture has been received.///
/// - Parameters:
/// - imageCount: Number of animations...
Preface: In fact, the installation steps of Docker official website is very detailed, if some people are not good at looking at English slower, you can directly look at me, I am also from the official website, the specific steps are as follows
1. Install dependency packages
$ sudo yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
2. Install the yum Library
$ sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
3.Install the latest version of Docker
$ sudo yum install docker-ce
4. Start Docker
$ sudo sys...

NodeDef attr’dilations’not found in the node definition, indicating that the execution version of NodeDef is not on the node definition, two inconsistent, respectivelyExecute inference codeandGenerate static graphsNodes are inconsistent (of course, because the execution environment is different from the generative environment, that is, the version problem).
The solution: If it’s deployed in the cloud, create a model graph in the cloud, and then combine CKPT and graph in the cloud to generate a static graph. If it is embedded, it is to adjust the local version of the same (th...
