Test on local device

To measure performance of the application, install the application from Actcast after actdk upload.

ActDK does not accelerate deep learning models in applications.

Let’s test your application with the device set up in the previous step.

Register Raspberry Pi for tests

Register Raspberry Pi for tests with the following command:

$ actdk remote add <IDENTIFIER_YOU_LIKE>@<REMOTE>
  • <IDENTIFIER_YOU_LIKE>
    • Identifier for your Raspberry Pi.
  • <REMOTE>
    • Hostname or IP address of the device.

Build an application

Build the Actcast application with the command below. This command build the application on the Raspberry Pi you selected.

$ actdk build <IDENTIFIER_YOU_LIKE>
  • <IDENTIFIER_YOU_LIKE>
    • The identifier used in the above actdk remote add.

See Actdk manual for more detail.

Test application

To check the operation, follow the steps below.

First, create act_settings.json , the application’s runtime settings file, using the following command. Please enter the setting values ​​you want to check for operation.

$ actdk generate act-settings

Next, check the operation of the created application on the Raspberry Pi using the following command. If the application supports display output and its settings are enabled, the image will appear on the display when you connect the Raspberry Pi to the display.

$ actdk run -a <IDENTIFIER_YOU_LIKE>

With the -a option, the command redirects stdout strings into your terminal. Without the -a option, the execution of actdk exits, ignoring any application’s output, but the application continues to run on the Pi.

If you want to try Take Photo on actsim, you can get the image in data URL format by executing the following command.

actdk photo

actdk stop stops the application on the Raspberry Pi.

$ actdk stop <IDENTIFIER_YOU_LIKE>

When you run actdk run and see exec user process caused "exec format error", check the following.

  • When developing using a scripting language, make sure that shebang is inserted correctly. In Python, you need to write #!/usr/bin/python3 at the beginning of the file
  • If you are developing in C-like language, check that your program is correctly compiled for arm32 and you are using an appropriate cross-compiler (like arm-linux-gnueabihf-gcc)

Next: Upload to Actcast

Previous: Setup Actsim
