== About

link:README.ja.adoc[この文書の日本語版]

This Addon is a link:https://github.com/sony/nnabla-c-runtime[NNabla C Runtime] that can be called from GDScript (Godot Engine 4.1).

The available trained models are the same as the original, only in NNB format.

=== Usage

[source,gdscript]

--

# Loading NNB files

var rf = FileAccess.open("res://model.nnb", FileAccess.READ)

var rf_size = rf.get_length()

var nnb = rf.get_buffer(rf_size)

rf.close()

# Creation of NNabla C Runtime

nn_crt = GDNNablaCRuntime.new()

# Initialization of NNabla C Runtime

nn_crt.rt_allocate_context()

# Set NNB file

nn_crt.rt_initialize_context(nnb)

# 1) Set input values

var ary_i = PackedFloat32Array([1.0])

nn_crt.rt_input_buffer(0, ary_i)

# 2) inference

nn_crt.rt_forward()

# 3) Get output values

var ary_o = nn_crt.rt_output_buffer(0)

# End processing

nn_crt.rt_free_context()

--

NOTE: For multiple inferences, 1, 2, and 3 can be repeated in succession.
