From the error message, we can see that it is related to the third-party package external/onnx tensorrt of oonnxruntime, and then we can see that
Onnx runtime – rel-1.7.2 is the third-party package onnx tensorrt. This package depends on tensorrt version 7.2.2, but I installed 7.0.0, which is too low.
The reason why I installed 7.0.0 is that I installed CUDA 10.0 before, and CUDA 10.0 supports tensorrt 7.0.0 at most.
terms of settlement:
(1) Download the appropriate version of onnxruntime again. The download is too slow and the time cost is too high.
(2) Update CUDA 11.0, CUDA 11.0 can support the latest tensorrt 7.2.3, re install CUDA and tensorrt reference tutorial.
GitHub upload failed: git push error: failed to push some refs to exception handling
reason
When GitHub created the project, the code was uploaded and the readme.md file was manually added to GitHub, but the local warehouse did not update the readme.md file.
resolvent
First, pull the files from the remote code base to the local code base, and then push the new code to the GitHub code base
Use the command to pull: git pull -- rebase origin master
and then upload: git push - U origin master

Successfully solved runtimeerror: CUDA runtime error (30)
RuntimeError: cuda runtime error (30)
I have been puzzled by this inexplicable error before. When I was ready to re install the driver and CUDA, I suddenly realized the root cause of this problem
the thing is, every time I want to run a program and go back to have a rest, I come back the next day to check. I’m disappointed that the program reported this error after running for a short time. Moreover, running the program after this error does not work. Only a simple and rude computer restart can solve the problem temporarily. But later found that if I have been using the computer during the day, the program will naturally run to the end, will not report such errors
so! It’s really CUDA, GPU’s problem, but it’s not because they have bugs, but because they are not playing a role in the rest, resulting in program errors! The fundamental reason is that my computer set a fixed time after the lock screen and automatically hang, so it is not CUDA. So there are such errors
If I set “don’t hang up” later, no such error will occur
write down your experience for the first time. I hope it can help you!
ERROR: KeeperErrorCode = NoNode for /hbase/master
Error: keepererrorcode = nonode for/HBase/master error occurred when inputting command in HBase shell
Error screenshot:
solution:
solution 1: close zookeeper, delete the version-2 folder under your own dataDir path, and then restart (used)
solution 2: add a paragraph in hbase-site.xml

The method can be used for the purpose of applying a tube, and for the purpose of this problem, I would like to say that there are three things: Core site HDFS site HBase site HBase. Rootdir . Plan 5: we have a large amount of disambiguation ( *) cause: namede on namespaceid and datanode It was found that the number of nodes under the nodal de nodal de nodal de paceme was not significant.

[Solved] IO exception: NL exception was generated
Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Io Exceptions: NL Exception was generated)
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Io Exceptions: NL Exception was generated)
Because the program has been running normally for a long time, so the basic rule out code logic problems, check the configuration found that the JDBC connection string problem;
The original URL was written as:
jdbc:oracle:thin:@(DESCRIPTION =(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))(LOAD_BALANCE = yes))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)(FAILOVER_MODE =(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))Where, DESCRIPTION appears twice, which is incorrect, and the correct connection string should be:
jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))(LOAD_BALANCE = yes))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)(FAILOVER_MODE =(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))Conclusion:
A JDBC connection string syntax error may result in Io exceptions: NL Exception was generated.

Node.js operation mysql error Cannot enqueue Handshake after invoking quit
Error Background:
When the database operation is performed for the first time, it is successful. The second time a database operation is performed, an error is reported as shown in the title.
The reason:
This is because after we close the connection with the.end() method, we need to re-call createConnection to recreate a connection.
Solutions:
For example, the following encapsulates a method that operates on database queries and additions. Each time a new connection is created using mysql.createconnection () before the database operation is performed, instead of putting it directly to the outermost layer.
var mysql = require('mysql');
exports.find=function(findSql,callback){
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '123456',
port: '3306',
database: 'namesharing',
});
connection.connect();
connection.query(findSql,function (err, result) {
if(err){
console.log('[SELECT ERROR] - ',err.message);
return;
}
connection.end();
callback(result)
});
}
exports.insert=function(addSql,addSqlParams,callback){
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '123456',
port: '3306',
database: 'namesharing',
});
connection.connect();
connection.query(addSql,addSqlParams,function (err, result) {

How to open X Display on the server side (locally operable remote interface)
The problem is this:
processes some photos on the server, and sometimes you want to look directly at the images on the server. But the server is Ubuntu Server, with no graphical interface. If we use feH, or cv2.imshow(), the error will be reported as follows:
Feh ERROR: Can’t open X display. It is running, yeah?
Solutions:
It should be in the server side ~/.bashrc file
export DISPLAY=localhost=10.0
On the server side the /etc/ssh/ssh_config file should be set to :
Host *
ForwardX11 yes
Use the following parameters when sshing to the server.
ssh -CAXY your-server-name@your-server-ip
