4. JupyterLab environment construction and use

The JupyterLab environment requires the computer and Raspberry Pi to be in the same LAN to use it normally. The factory system starts the JupyterLab service by default.

4.1 Get the Raspberry Pi IP address

The first time the factory image is turned on, you need to configure the network connection in the startup program, then enter the remote control interface, press the button in the lower right corner of the Rider-pi screen, and you can query the corresponding IP address.

4.2 Start the JupyterLab environment

Open the browser on the computer and enter the IP address + port number of the Raspberry Pi in the address bar.

192.168.2.112:8888

Then enter the JupyterLab login password (yahboom) to log in.

4.3 HelloWorld

Write and run the HelloWorld program.

• Create a new file and name it HelloWorld

Right-click the file browser menu bar, select "New Notebook File (New Notebook)", select Python3 for the kernel, and then rename it to HelloWorld
