com.android.ddmlib.AdbCommandRejectedException: device offline Error while Installing APK (How to Fix)

com.android.ddmlib.AdbCommandRejectedException:device offline
Error while Installing APK

The problem is that ADB is killed, just restart it
There are three ways:
1. Plattform-tools can be found in the SDK file, and adb can be found in this folder.
Double-click ADB to restart it

Second, you can also perform a two-step command operation in CMD:
1, the adb kill server
2, the adb start – server

Restart the computer

Pytorch RuntimeError CuDNN error CUDNN_STATUS_SUCCESS (How to Fix)

When I used RNN in Pytorch and sent it to the GPU for computation, there was:
RuntimeError: CuDNN error: CUDNN_STATUS_SUCCESS
Before the error appeared, my environment was:
OS: Ubuntu 16.0.4
GPU: NVIDIA GForce RTX 2080 (view GPU and driver information can be used command: nvidia-smi)
CUDA: cuda9.0
cudnn: 7.x for cuda9.0
Look up the solution on the Internet, in fact, encountered this kind of problem is very simple, is
1. Update cuda and cudnn
change your cuda and cudnn to 9.2 or 10.0 or above the lowest version of cuda supported by your GPU;
2. Update pytorch and torchvision versions
remember, after updating cuda and cudnn, be sure to update pytorch to a version suitable for your cuda, such as torch0.4.1 for cuda9.2.
After the above 2 steps, you can basically solve this problem. The reference method is as follows:

LaTeX Error: Can be used only in preamble

LaTeX Error: Can be used only in preamble
translation: Xovee
translation time: June 11, 2020
LaTeX Error: Can be used only in preamble
This error occurs if you introduce a package or class in the body of the text, rather than in the preamble. Before the command \begin{document}, everything is called a prologue. In the prologue, you define the type of document, the language of the document, and many basic Settings. For example, the preface to a general document looks something like this:

\documentclass[12pt, letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}

\title{First document}
\author{Hubert Farnsworth \thanks{funded by the ShareLaTeX team}}
\date{February 2014}

If you introduce the package in the body (after \begin{document}) instead of in the preface, you will get this error:

To resolve this error, you must ensure that all packages introduce the command \usepackage{… }, and \ documentClass []{… }, before the \begin{document} command. If you want to learn more about LaTeX document structure, please refer to this document.

(Solved) pytorch error: RuntimeError: cuDNN error: CUDNN_STATUS_EXECUTION_FAILED (install cuda)

RuntimeError: cuDNN error: CUDNN_STATUS_EXECUTION_FAILED
Reason: Pytorch and CUDA versions are not right
(It is also possible that there is not enough memory space, you can change the virtual space size)
Uninstall Pytorch: Conda Uninstall Pytorch, and if you install CUDA, it will automatically override the CUDA version.
Open CMD and type from the command line

import torch
print(torch.__version__)
print(torch.version.cuda)


Similar errors occur if the cudA version is not installed with the torch version.

Here’s how to install CUDA:
1. Open the NVIDIA control panel to view the CUDA version supported by the current video card driver:


2. Download CUDA address
https://developer.nvidia.com/cuda-toolkit-archive
Or offline installation package download required in https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/linux-64/. Tar..bz2
Background Conda Install XXXX.. tar.bz2
Install after installation is complete

First anaconda Conda switches to the domestic source

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge 
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/

conda config --set show_channel_urls yes

Conda Install Pytorch Torchvision Cudatoolkit =10.0
Install other packages
Pytorch official website: Pytorch official website

Download according to the actual situation:

3. After successful download, double-click the exe file to install.
The verification method for successful installation is to enter nvcc-v under CMD

The installation was successful. You can see in system variables:


Or you can see nvCC.exe under the installation path

Syntax error, insert “VariableDeclarators” to complete LocalVariableDeclaration

When you use a variable named static today:

package com.day7.demo4;

public class Pengue {
    String name;
    String sex;
    int love=0;
    int health=60;

    static final String SEX_MALE = "Q-boy";
    static  final String SEX_FEMALE = "Q-girl";

    public Pengue() {
        super();
    }

    public Pengue(String name, String sex, int love, int health) {
        super();
        this.name = name;
        this.sex = sex;
        this.love = love;
        this.health = health;
    }

    public void print() {
        System.out.println("name:"+name+",sex:"+sex+",intimacy："+love+",Health:"+health);
    }

}

For Penguetest.java, go ahead:

System.out.print("Please select the sex of your Penguin：(1.boy 2.girl)");
            int num = sc.nextInt();
            if (num == 1) {
                 Pengue.SEX_MALE;
            }else if (num ==2) {
                 Pengue.SEX_FEMALE;
            }

The error is as follows:

Syntax error, insert "VariableDeclarators" to complete LocalVariableDeclaration

It is correct after modification as follows:

System.out.print("Please select the sex of your Penguin：(1.boy 2.girl)");
            int num = sc.nextInt();
            if (num == 1) {
                pengue.sex = Pengue.SEX_MALE;
            }else if (num ==2) {
                pengue.sex = Pengue.SEX_FEMALE;
            }

Assign it to a variable, because that’s the same thing as 1; Because SEX_MALE is now constant, avoid this error in the future;

ERROR 1524 (HY000): Plugin ‘auth_socket’ is not loaded How to Fix

Mysql was installed in Ubuntu and this error occurred when I opened it:

ERROR 1524 (HY000): Plugin ‘auth_socket’ is not loaded

A face overwhelmed
baidu to only on stackoverflow. It’s a little weird to find something that says’ unix_socket ‘
https://stackoverflow.com/questions/37879448/mysql-fails-on-mysql-error-1524-hy000-plugin-auth-socket-is-not-loaded
And twice, every time I want to use the database, this problem always comes up.
solution:

sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start

Just restart it and you can use it

Solve the problem: Something’s wrong–perhaps a missing \item. \end{thebibliography}

Sometimes when we compile papers with latex, we encounter problems related to BIB, as follows:
Something’s wrong–perhaps a missing \item. \end{thebibliography}
The same latex documents are fine to compile in Windows but not on MAC.
The underlying problem is the *.bbL file in the directory where *.tex resides. This file is handled differently on Windows and MAC. When there are no references in the article, Windows compiles, but MAC does not.
So here’s the solution:
(1) First close *.tex file, and then delete *.bbL file;
(2) Open *.tex file and add the statement \ {*} anywhere in the article;
(3) Compile again, there is no problem.

Install koa error Cannot find module’internal/fs’

Scenario: Node and NPM are installed locally, but the node version is lower than 8.0.0, so the node version management tool N is used to upgrade the version. After the upgrade, koA is installed and an error is reported

Cause: Changes to the node version on which NPM depends
Solution: 1. Remove NPM NPM Uninstall NPM-g 2. Reinstall Node, because NPM will be installed at the same time that Node is installed
