NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running
The main reason is that the system kernel has been upgraded, which leads to the mismatch between the new version kernel and the original graphics driver. Just execute two commands
sudo apt-get install dkms
sudo dkms install -m nvidia -v 440.44(440.44 indicates the driver version number)
Use the command ll/usr/SRC/to see that there is a nvidia-440.44/folder below

In the XML of the title, the ID of textview is title
<include
android:id="@+id/title"
layout="@layout/titlebar" />
Use include < in the main interface> When introducing a layout, the layout ID set is also the title,
when using viewbinding, there will be confusion, so the ID name should be set to different.

When configuring webpack.config.js to automatically package, an Error: Cannot find module’@babel/core’ error occurred. I
initially thought that babel-core was not installed. After reinstalling babel-core several times, it still doesn’t work. Compared with the previous project, it is found that the version of babel-loader is different. The previous one was @7.1.5 version, but now it is @8.0.0 version.
Install back to the @7.1.5 version with a dubious mood
npm uninstall babel-loader
npm install babel-loader@7.1.5
And then npm run buildfound success!
I’m a little puzzled, it’s only a few days since the last installation, so I updated it to [email protected]. And it doesn’t support the original configuration anymore. No solution was found on the Internet, and the principle is still unclear. Mark it first, and after solving the problem of @8.0.0, I will come back to add.
Attach webpack.config.js code:
var webpack = require('webpack');
var path = require('path');
var HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
entry: __dirname + '/client/root/index',
output: {
path: path.join(__dirname + '/dist'),
filename: 'bundle.js',
},
module: {
loaders : [{
test :/(\.jsx|\.js)$/,
exclude : /node_modules/,
loader :'babel-loader',
options:{
presets:[
"env", "react",
]
}
},
{
test: /\.css$/,
loader: 'style-loader!css-loader'
},
{
test: /\.less$/,
loader: 'style-loader!css-loader!less-loader'
},
{
test: /\.(jpg|.png)$/,
loader: 'url-loader'
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: __dirname + '/client/views/template.html'
}),
]
}
Regarding the [email protected]cause of the error has been found, thank you @Sky__zt for your answer.
(Forgot to read the official document)
The official default babel-loader | babel corresponding version needs to be the same: that is, the babel-loaderlatest version is requiredbabel
For details, please refer to: “npm_babel-loader”
Two solutions: 1. Roll back the lower version
npm install -D babel-loader@7 babel-core babel-preset-env
npm install -D babel-loader @babel/core @babel/preset-env webpack
phenomenon:
When I started the project today, this project used the Elasticsearch service and found that the background reported this error:
Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: /127.0.0.1:9300
The error message is shown as below:
the reason:
This project uses the Elasticsearch search service, and the error message also prompts key information such as elasticsearch.transport. In fact, this error is caused by the failure of the Elasticsearch service to start successfully.
solution:
Restart the Elasticsearch service (if it doesn’t work once, try shutting it down and then restarting it).
I restarted several times before it succeeded.
When I created a new Vue project today, I made a mistake like the title, which was disgusting at that time
Try the method of online God
Find the content to be modified by C:: (users/owner). Vuerc “ Usetaobaoregistry “: false, if the value is true or false, it is not easy to use
Then a whim called CMD as administrator to recreate the project successfully
For reference only, by the way, ask if there is a big God how to solve this problem: how to make the CMD run smoothly under the permission of non administrator?
Today, we use C + + to encapsulate a function of OpenSSL. When a parameter forgets to assign a value, (the last one) prompts this (as shown in the figure below, I intentionally set it to a null value). But it’s hard.
Springboot project running error:
If you check the directory, the problem lies in the URL in the controller
(1) if: @ requestmapping (“/”)
the URL should be written:
(2) if the URL is like this:
Then @ requestmapping (“/ users”)
is a very simple question… As a result, I took a long walk to look at the XML file and properties for half a day… To record this little problem
