Kettle Flash Back Error:The graphical interface cannot be opened. There is an ETI installation problem

1. Install JDK (version 1.6 or above)

2. JDK environment variable configuration is shown in the figure (the following values are their own installation directory):

3. For the first error, directly flash back, find the spoon.bat in the data integration directory, right-click Notepad to edit, and find the following code to modify

if "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=java.exe
if not "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=javaw.exe

change to 

 if "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=java.exe
if not "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=java.exe

4. If you change the first error and then flash back (modify the memory configuration in spoon.bat)


 if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms1024m" "-Xmx2048m" "-XX:MaxPermSize=256m"

change to

 if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms512m" "-Xmx1024m" "-XX:MaxPermSize=256m"

5. If the above errors are corrected, the following occurs:

You need to modify the variable value in spoon.bat

pushd "%JAVA_HOME%\jre\bin"
if exist java.exe goto USEJAVAFROMPATH
goto USEJAVAFROMPATH
:USEJAVAFROMPENTAHOJAVAHOME
FOR /F %%a IN ('.\java.exe -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:USEJAVAFROMPATH
FOR /F %%a IN ('java -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:CHECK32VS64BITJAVA
IF %IS64BITJAVA% == 1 GOTO :USE64

add a line:（set IS64BITJAVA=1，make them all TRUE）

pushd "%JAVA_HOME%\jre\bin"
if exist java.exe goto USEJAVAFROMPATH
goto USEJAVAFROMPATH
:USEJAVAFROMPENTAHOJAVAHOME
FOR /F %%a IN ('.\java.exe -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:USEJAVAFROMPATH
FOR /F %%a IN ('java -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:CHECK32VS64BITJAVA
set IS64BITJAVA=1

IF %IS64BITJAVA% == 1 GOTO :USE64

7. After the modification is successful, the graphical interface can be opened after saving

[Solved] Django Models Error: Manager isn‘t accessible via UserInfo instances

Error content: manager isn’t accessible via userinfo instances

Error reason: it is because the variable name is used instead of the object name (model class) when calling the model object, for example:

user = UserInfo()
user_Li = User. Objects. Filter (uname = username), this error will be reported in this call

Solution: call the objects method with the object name

user = UserInfo()
user_li = UserInfo.objects.filter(uname=username)

this.$el.querySelectorAll is not a function [How to Solve]

Problem description
when using El tree, the error this. $el.queryselectorall is not a function is reported, which makes the tree unable to render

Problem resolution
refer to the following code snippet

	<el-tree
        :data="treeData"
        show-checkbox
        node-key="id"
        ref="functionTree"
    ></el-tree>

Most of the errors reported are incorrect data bound by El tree. Data errors can be divided into the following two types:

Case 1:

Cause: wrong format of treeData data.
Solution: check the treeData data format, the data bound by :data must be an array.

Case 2:

Cause: The treeData array contains dirty data such as null
Solution: Delete the null and other dirty data in the data

[Solved] Git Push Error: &fatal: the remote end hung up unexpectedly

First of all, this is my error report

Total 123 (delta 0), reused 0 (delta 0), pack-reused 0
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
send-pack: unexpected disconnect while reading sideband packet
fatal: the remote end hung up unexpectedly

Reason: the project is too large and the network is not working, resulting in an error that the download is too slow and exceeds the time trigger

Method 1: modify the cache size

git config --global http.postBuffer 524288000

Change the warehouse configuration to the following

[core]
	
   repositoryformatversion = 0
	
   filemode = false
	
   bare = false
	
   logallrefupdates = true
	
   symlinks = false
	
   ignorecase = true


[remote "origin"]
	
   url = https://github.com/dhsb-4/SSM.git
	
   fetch = +refs/heads/*:refs/remotes/origin/*


[branch "master"]
   remote = origin
   merge = refs/hefs/master

[http]
  postBuffer = 1048576000

Configuration path (open with Notepad)
push again after modification

Method 2: configure the minimum speed and minimum speed time of GIT

git config --global http.lowSpeedLimit 0
git config --global http.lowSpeedTime 999999

– Global: for the current user – system: for all users

Method 3: use SSH path

I use this method to solve this problem

[Solved] Tsingsee green rhinoceros video pedestrian intelligence detection test error panic: runtime error

In the previous article, we introduced the test of tsingsee green rhinoceros video pedestrian intelligent detection function in the scenic spot project. In the scenic spot project system, an error occurred when replacing the local file with the error message: “panic: runtime error: index out of range [1] with length 1”. This error means that the program runs beyond the index range, which will cause the program to crash.

First look at the code:

var allFile = ""
for _, dirfile := range dirfiles {
   fname := dirfile.Name()
   n := strings.Split(fname, "_")[1]
   allFile += fmt.Sprintf("%s/%s;", dir, n)
}
allFile = allFile[:len(allFile) -1]

nameSplit := strings.Split(arr[index].Filename, ";")
   log.Println("There are multiple files that need to be replaced:" + arr[index].Filename)

   DoLocalFile(0, nameSplit,  func() {
      index+=1
      DoValueToReplaceSource(arr, index, cb)
   })

   return

The above code is to splice the video files in all folders and use semicolons (“;”) as separators. However, an error will appear in the code: reference a slice with nil, that is, an element with subscript 0. This error will cause an index out of range error in the code, which will trigger panic and make the program unable to run normally.

The semicolon (“;”) segmentation is used here, so as long as a judgment is made, the character segmented from the semicolon needs to be greater than 1. If it is less than or equal to 1, an error will occur. The code is modified as follows:

nameSplit := strings.Split(arr[index].Filename, ";")
if len(nameSplit) > 1 {
   log.Println("There are multiple files that need to be replaced:" + arr[index].Filename)

   DoLocalFile(0, nameSplit,  func() {
      index+=1
      DoValueToReplaceSource(arr, index, cb)
   })

   return
} else {
   if IsExists(arr[index].Filename) {
      ChangeFile(arr[index].Filename)
   } else {
      log.Println("No path to this file")
   }
}

After modification, the error can be solved. Tsingsee Qingxi video will continue to expand the functions and advantages of the live video broadcasting system. On the one hand, it realizes intelligent judgment through AI intelligent analysis. On the other hand, it obtains the most vivid data information and carries out accurate calculation through Internet of things, big data and other technologies. You are welcome to understand or test.
