Bring the examples to your organization

Using the Docker Image

To use the examples, a README.md instruction file will be provided inside the example repositories. Sometimes, a public docker image will also be provided to quickly test so you don't need to import it and clone the entire repository.

If you want to quickly test the transformation blocks, head to your Edge Impulse organizaton, go to Custom blocks->Transformation and click on + Add new transformation block:

Replace the Docker Container by the one provided in the example above, the operation type and the optional parameters (check the examples README.md instruction to set the parameters):

.

Using Edge Impulse CLI

To modify the code and push the blocks to your organization, you will need to use Edge Impulse CLI.

1. Clone this repository:

git clone https://github.com/edgeimpulse/transformation-blocks.git

2. Navigate to the desired example:

cd transformation-blocks/hello-edge

3. Create the transformation block:

edge-impulse-block init

4. Push the transformation block to your organization:

edge-impulse-block push

Contributing to this repository

We welcome contributions to this repository. Both improvements to our own transformation blocks, as well as new and well-tested transformation blocks for other use cases. Make sure to provide a public dataset - or subset of this dataset - so everyone can reproduce your workflow seamlessly.
