Uploading Models

This walkthrough describes how to upload new ModelPack 2D vision models and radar-vision fusion models to the Raivin.

Getting New Models

You can train models using EdgeFirst Studio, both ModelPack Vision models and Fusion Radar models. Once the models are trained, they can be downloaded from their respective, completed training sessions.

Uploading Models to the Raivin

In the SCP section in the SSH Tutorial, files can be uploaded to the Raivin using the command:

scp input_file torizon@verdin-imx8mp-XXXXXXX:.

Note

The above command assumes you have an SSH client, such as OpenSSH, installed. Please review the SSH documentation to confirm.

For the following examples, we will have the Fusion model of fusion.tflite and the ModelPack model modelpack.rtm that we want to upload to target device verdin-imx8mp-07130049.

First, we need to upload the files to the Raivin target using SCP:

$ scp fusion.tflite torizon@verdin-imx8mp-07130049:.
$ scp modelpack.rtm torizon@verdin-imx8mp-07130049:.

We should be able to confirm the files are there by using commands via SSH.

$ ssh torizon@verdin-imx8mp-07130049 ls fusion.rtm modelpack.rtm
fusion.tflite  modelpack.rtm

These files will be the /home/torizon directory, so their absolute filenames will be /home/torizon/fusion.tflite and /home/torizon/modelpack.rtm. Once the files have been uploaded, we can then configure the device with the files.

Deploying a New Model to the Model Service

There are two ways to deploy a new, 2D model to the Raivin's Model Service: the Web UI Interface or via the command-line.

From the Raivin Web UI

From the Model Service Configuration page, enter the absolute filename /home/torizon/modelpack.rtm in the "MODEL" text-box. Also, confirm the "Draw Boxes" check box is enabled, as the current trainer only supports 2D Box detection. Hit the "Save Configuration" box and continue on.

Model Configuration Page

Remember to save the configurations at the end of the process. The Model Configuration page can be accessed via the following url: https://verdin-imx8mp-xxxxx/config/model

Manual Model Deployment

In case the manual deployment is needed, you need to connect to the device via SSH:

$ ssh torizon@verdin-imx8mp-15141030

and edit the model parameters in /etc/default/model

$ vi /etc/default/model

then restart the model service using the systemctl command

$ sudo systemctl stop model
$ sudo systemctl start model

Note

Rember to use sudo to start and stop model services

Now the model is running, open the Raivin's WebUI, go to the Segmentation Page, and check the camera to see the model detection the object.
Deployment Results

Deploying a New Model to the Fusion Service

As the Fusion Service Configuration page does not currently have a line item for Model, you will need to SSH into the device and edit the /etc/default/fusion file, using the following the command:

$ sudo vi /etc/default/fusion

Change the model line to point to the new Fusion model /home/torizon/fusion.tflite:

## The radar model
MODEL = "/usr/share/fusion/radarexp-ultra-short.tflite"
##MODEL = "/home/torizon/fusion.tflite"

After that, restart the Fusion Service using the following command:

$ systemctl restart fusion

Summary

At this point, the new models should be uploaded to the Raivin and you should be able to the outputs on the Segmentation View page.
