Installation Guide for Machine Learning and Script Integration Services

Overview 

The setup will install Klera Python connector (Python Script Integration Services) and Machine Learning
services

 Prerequisites 

• Anaconda Python 3.7.3 
  • - Compatible versions:
    A) 3.6.1 or Greater
    B) 3.7.0 or Greater
    C) 3.8.0 or Greater
• Klera SDLC Version >= 4.1.39
• The following windows updates must be installed on the system:
  
  Windows8.1-KB2919442-x64.msu 
  Windows8.1-KB2919355-x64.msu  

Note: For hardware and software requirements, please refer to the Klera Script Integration and Machine Learning reference documents.  

Pre-Installation Checks  

Before running the setup, kindly verify that Python is installed properly, and the system environment variable PATH is updated. 

• Open command prompt in Administrator mode. 
• Go to folder where Anaconda Python is installed. 
  • Let’s say Python is installed in folder,
    'C:\Users\demouser\AppData\Local\Programs\Python\Python38’, then
  •  Open command prompt 
  • Run C:\Users\demouser\AppData\Local\Programs\Python\Python38\Python.exe
  • You will see ‘Python console’. Enter the below command:
                       > import ssl 
  • If Python is installed correctly and system environment variable PATH is updated, then it will not return any error. 
  • If there is an error, (Import.dll not found), then add the below path at the start of the PATH in system environment variables. 
                  C:\Users\demouser\AppData\Local\Programs\Python\Python38\Library\bin  
                  (Assuming Python is installed in C:\Users\demouser\AppData\Local\Programs\Python\Python38)        
    • Say, existing system environment “PATH” Variable is C:\Program Files (x86)\Common Files\Oracle\Java\javapath;        
    • Then, final Environment PATH Variable after updating is C:\Users\
      demouser\AppData\Local\Programs\Python\Python38\Library\bin;C:\Progra
      m Files (x86)\Common Files\Oracle\Java\javapath;             
• Now, open a new command prompt and retry the Python command  
                         > import ssl 

In case if you still experience any difficulty, please contact System Administrator. Anaconda Python reinstallation may be required.

Post-Installation Steps 

 After the installation is complete, configure “KleraScriptIntegrationService" and "KleraScriptPythonCoreService" to run as Administrator. 

1.  Go to windows services. (Run services.msc from windows Run or command prompt)
   
   
2. Select the service "KleraScriptIntegrationService".
3.  Right-click and select "Properties”. 
   
4. Select the "Log On" tab, then check ’This account’. Provide ID and Password (of Administrator). Click OK.
