In today's fast changing technology landscape, speed is everything. For quick adaptation and usage RAiV has a web based graphical user interface. Users can login to RAiV's web interface by using a browser. After the login, users can upload their python codes and AI model. With this web based approach and our Python SDK, you can develop your custom applications in short time and decrease your time to market.

How it Works?

As we have explained in our previous posts, RAiV has a sandboxed Python environment to run user's Python codes. After the python files are uploaded by using the web interface, RAiV checks the codes for semantic correctness and executability. If all of the codes pass the checks, then RAiV runs them.

Preliminary

Before running your first code, please check that:

  • Your browser is up to date.
  • Power cable is connected to RAiV.
  • Ethernet cable is connected from PC to RAiV, directly.
  • Your computer's wired network interface has the following configuration:
    • IP 192.168.10.2
    Netmask 255.255.255.0
    Gateway 192.168.10.1
  • RAiV is powered on.

How to run your code

In order to run your Python code, you must have a file with the name user_main.py. The entry point for your Python code is the main() function in the user_main.py file. In other words, RAiV searches for the user_main.py file and calls the main() function.

Prepare & Upload Your Python Code

In this post we are going to demonstrate how to run the simplest Python script, that is the "Hello World" script:

def main():
    # Greet the world
	print("Hello World")

if __name__ == "__main__":
    main()

Copy the code above and save it to the user_main.py file.

Now, use your web browser to open the web based graphical user interface of RAiV. The default IP address of RAiV is:

http://192.168.10.55

When the page loads, the login screen below is shown:

RAiV Web Interface Login Page
RAiV Web Interface Login Page.

Login as user. Default user name and password are:

    Name user
    Password 123456

After successfully login as user, the user web interface is displayed. Click to "Python Deployment" button on the right of the screen to open the Python upload panel:

RAiV User Page with Python Deployment Panel Opened
RAiV User Page with Python Deployment Panel Opened.

Click to the "Upload Python Files" button on the "Python Deployment" panel. The browser will show a file selection dialog box. Select the previously created user_main.py for uploading. After the successful upload, the file displayed on Python Deployment panel:

Python Deployment Panel with user_main.py file
Python Deployment Panel with user_main.py file.

Live Action

Now that the user_main.py file has been uploaded, let's check its execution. Click to "Python Settings" button on the right of the screen to open the Python settings panel:

RAiV User Page with Python Settings Panel Opened
RAiV User Page with Python Settings Panel Opened.

After opening the "Python Settings" panel, hover over the black "Console Output" area. When you hover over the black area, two buttons will appear "Get Output" and "Copy". Press the "Get Output" button to retrieve the console output of the python console.
