2. Solution:

(1) Use the browser to run jupyter to check the errors (it is recommended to skip)

It is recommended to skip this step! The explanation here is only to record the complete error resolution steps.

Use the command to install jupyter,

pip install jupyter

Open the .ipynb file in the browser and run it again. The error is different from that in Visual Studio Code:

Could not locate zlibwapi.dll

(2) Install Zlib

Install Zlib as this tutorial. the error will be solved!

[Solved] Cause: java.sql.SQLException: TDengine ERROR (8000000b): Unable to establish connection

FQDN is not configured during installation and configuration. There is no error when starting spingboot. The following error is reported when inserting data

Solution:

vi /etc/taos/taos.cfg

/var/lib/taos/dnode/dnodeEps.json

The local windows system must install the client tdengine-client

Hosts to be set, as shown in the following figure

[Solved] CCS cannot connect to emulator error: Error initializing emulator

Error display:

Error initializing emulator:
(Error -2083 @ 0x0)
Unable to communicate with the emulator. Confirm emulator configuration and connections, reset the emulator, and retry the operation.
(Emulation package 5.1.232.0)

Cause:
the driver is wrong. The card used is Feiteng, but the driver in CCS is ti. It can be replaced.

Solution:
Open ccs/ccs_base/emulation/drivers, and then replace the Feiteng driver

[Solved] appium Original error: Could not proxy command to the remote server. Original error: socket hang up

When the appium inspector records the app of oppo real machine, an error occurs in the third or fourth step of operation:

Call to 'tap' failed
[performTouchAction([{"action":"tap","options":{"x":782,"y":1358}}])] Error response status: 13, , UnknownError - An unknown server-side error occurred while processing the command. Selenium error: An unknown server-side error occurred while processing the command. Original error: Could not proxy command to the remote server. Original error: socket hang up

Appium error log:

After investigation, the solution is as follows:

1. When appium desktop starts, it is necessary to use advanced mode, –session-override is set to true;

2. Enter the OPPO mobile phone, go to Settings->Apps->Special application permissions, and set appium settings, io.uiautomator2.server, io.uiautomator2.server.test in the permission list to allow;

After this setting, restart appium inspector, record, and no longer report that error.

I guess that appium suddenly failed to record before, or it was related to appium’s application permissions on OPPO mobile phones. The system services in the mobile phone may suddenly force stop Force stopping io.appium.uiautomator2.server.test

 

[Solved] Error in Summary.factor ‘sum’ not meaningful for factors

 

Question:

The root cause is the wrong data type.

The factor type has no sum method

#create a vector of class vector
factor_vector <- as.factor(c(1, 7, 12, 14, 15))

#attempt to find min value in the vector
sum(factor_vector)

Error in Summary.factor(1:5, na.rm = FALSE) : 
  ‘sum’ not meaningful for factors

Solution:
Convert to numeric values and use the as.numeric function.
mydata$value<-as.numeric(mydata$value)
is.numeric(mydata$value)

#convert factor vector to numeric vector and find the min value
new_vector <- as.numeric(as.character(factor_vector))
sum(new_vector)

#[1] 49

Complete error:

#create a vector of class vector
factor_vector <- as.factor(c(1, 7, 12, 14, 15))

#attempt to find min value in the vector
sum(factor_vector)

Error in Summary.factor(1:5, na.rm = FALSE) : 
  ‘sum’ not meaningful for factors

Other (the minimum value can be obtained for numeric value, string and date type)

Numeric value, string and date type can all be maximized. Similarly, the maximum value can be obtained.

numeric_vector <- c(1, 2, 12, 14)
max(numeric_vector)

#[1] 14

character_vector <- c("a", "b", "f")
max(character_vector)

#[1] "f"

date_vector <- as.Date(c("2019-01-01", "2019-03-05", "2019-03-04"))
max(date_vector)

#[1] "2019-03-05"

The R language is called R partly because of the names of the two R authors (Robert gentleman and Ross ihaka) and partly because of the influence of Bell Labs s language (called the dialect of s language).

R language is a mathematical programming language designed for mathematical researchers. It is mainly used for statistical analysis, drawing and data mining.

If you are a beginner of computer programs and are eager to understand the general programming of computers, R language is not an ideal choice. You can choose python, C or Java.

Both R language and C language are the research achievements of Bell Laboratories, but they have different emphasis areas. R language is an explanatory language for mathematical theory researchers, while C language is designed for computer software engineers.

R language is a language for interpretation and operation (different from the compilation and operation of C language). Its execution speed is much slower than that of C language, which is not conducive to optimization. However, it provides more abundant data structure operation at the syntax level and can easily output text and graphic information, so it is widely used in mathematics, especially in statistics

[Solved] vcpkg Error: Error: Could not detect vcpkg-root.

Phenomenon

When transferring vcpkg from CentOS 8 to CentOS virtual machine through SCP, the above error is always reported when running vcpkg

Root cause

The Linux environment needs to add the system variable $VCPKG_ROOT

Solution:

vim ~/. bash_profile

Add a line:

export VCPKG_ROOT=”/home/devuser1/vcpkg”

Change the directory to your directory

Close the shell, reconnect, and everything is OK

[Solved] WebPack Error: Watchpack Error (watcher): Error: ENOSPC: System limit for number of file watchers reache

The following error occurs when the Vue project runs the NPM run serve command in the deepin20 system environment: (webpack error: watchpack error (watcher): error: enospc: system limit for number of file watchers reach)

Cause analysis: the limitation of Linux system causes this error!

Solution:

The problem can be solved by executing the following commands on the terminal:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
sudo sysctl --system

[Solved] Error in Summary.factor ‘max’ not meaningful for factors

Question:

The root cause is the wrong data type.

The factor type has no max method

#create a vector of class vector
factor_vector <- as.factor(c(1, 7, 12, 14, 15))

#attempt to find max value in the vector
max(factor_vector)

#Error in Summary.factor(1:5, na.rm = FALSE) : 
#  'max' not meaningful for factors

Solution:

Convert to numeric value or string, here convert to numeric value.

mydata$value<-as.numeric(mydata$value)
is.numeric(mydata$value)

#convert factor vector to numeric vector and find the max value
new_vector <- as.numeric(as.character(factor_vector))
max(new_vector)

#[1] 15

Full error:

#create a vector of class vector
factor_vector <- as.factor(c(1, 7, 12, 14, 15))

#attempt to find max value in the vector
max(factor_vector)

#Error in Summary.factor(1:5, na.rm = FALSE) : 
#  'max' not meaningful for factors

 

Other (numeric value, string, date type can be the maximum value)

Numeric value, string and date type can all be the maximum value, and similarly, the minimum value can be obtained.

numeric_vector <- c(1, 2, 12, 14)
max(numeric_vector)

#[1] 14

character_vector <- c("a", "b", "f")
max(character_vector)

#[1] "f"

date_vector <- as.Date(c("2019-01-01", "2019-03-05", "2019-03-04"))

[Solved] unhandled error during execution of watcher callback

report errors

unhandled error during execution of watcher callback

analysis

When drawing data with the Echorts icon, an error is reported: unhandled error during execution of watcher callback. The reason for the prompt is that the Echorts chart is rendered before the data is obtained in the current year, which results in the chart cannot being displayed and an error being reported

Solution:

Before data rendering, make a non-empty judgment
for example:

if(value){
	Start rendering data
}

or

if(value !== undefined){
	Start rendering data
}

[Solved] qt phonon Play wav file Error:“symbol lookup error: /usr/lib/kde4/plugins/phonon_backend/phonon_gstreamer.so: undefined symbol: _ZNK6Phonon11MediaSource3mrlEv”

Leave a reply

Linux:
there is no problem with using it before. After reinstalling the system, it will prompt qt to use phonon to play the wav file, and it will prompt “symbol lookup error: /usr/lib/kde4/plugins/phonon_backend/phonon_gstreamer.so: undefined symbol: _ZNK6Phonon11MediaSource3mrlEv ” this error, and then the program crashes, as if to say the reason for this library version.

My Solution:
find the libphonon_gstreamer.so library in the qt installation directory, then copy it to the directory indicated by the error (rename libphonon_gstreamer.so to phonon_gstreamer.so), replace the phonon_gstreamer.so inside, and return to normal.

Cause Analysis 1 The Tomcat used by the server, the compilation and packaging method is not set to war [the default packaging method is jar]
Scenes Unable to start when starting projectimage

1. Set the packaging method to war in pom.xml
image-20220727191657448

Cause Analysis 2 Port is occupied
Scenes Unable to start when starting projectimage

1. First check the startup status of the port

​ Win+R Enter cmd to open the DOS command box, enter netstat -ano | findstr 8060 [where 8060 is the port number of the running project] If this is image
displayed, it means that the background port 8060 is still running, and the PID is 10316, so kill the port process, Just restart the project

2. Kill the process, choose one of the two methods

​ 2.1, Ctrl + alt + delete, start the task manager, find the corresponding program according to the PID, right-click to end the taskimage

​ 2.2. According to tasklist | findstr 10316, query what program is occupying port 8060, of which 10316 is the PID queried above.image

​ Just continue to execute taskkill /f /t /im java.exe
​ (or) directly execute taskkill /pid 10316 -t -f to force kill the process
