This Edge Impulse CLI is used to control local devices, act as a proxy to synchronise data for devices that don't have an internet connection, and to upload and convert local files. The CLI consists of three tools:

• edge-impulse-daemon - configures devices over serial, and acts as a proxy for devices that do not have an IP connection.
• edge-impulse-uploader - allows uploading and signing local files.
• edge-impulse-parquet-converter - converts Parquet files into Edge Impulse Data Acquisition files.

Installation

1. Install Node.js v10 or higher on your host computer.

2. Install the CLI tools via:

    $ npm install -g edge-impulse-cli
   

Afterwards you should have the tools available in your PATH.

Troubleshooting

Tools version "2.0" is unrecognized (Windows)

If you receive the following error: The tools version "2.0" is unrecognized. Available tools versions are "4.0", launch a new command window as administrator and run:

$ npm install --global --production windows-build-tools
$ npm config set msvs_version 2015 --global

EACCES: permission denied, access '/usr/local/lib/node_modules' (macOS)

This is indication that the node_modules is not owned by you, but rather by root. This is probably not what you want. To fix this, run:

$ sudo chown -R $USER /usr/local/lib/node_modules

Error: Can’t find Python executable (Windows)

If you receive an error such as:

gyp ERR! stack Error: Can’t find Python executable “C:\Users\vale.windows-build-tools\python27\python.exe”, you can set the PYTHON env variable.

You need Python 2.7 installed on your machine. We use a binary package to handle serial communications, and this package is built using the node-gyp build system. This build system requires Python 2.7 installed.
