This tool supports many kinds of Renesas’ microcomputers.
The tool can convert from trained model of “PyTorch”, “Keras”, “Tensorflow”, or 8-bit quantized model of “TensorFlow Lite” and import it easily to e2 studio that is Renesas' integrated development environment.
These kind of Renesas products are suitable to be used for relatively small-scale AI for endpoints.
