fc

ray.rllib.utils.numpy.fc(x: ndarray, weights: ndarray, biases: ndarray | None = None, framework: str | None = None) → ndarray

Calculates FC (dense) layer outputs given weights/biases and input.

Parameters:

• x (ndarray) – The input to the dense layer.

• weights (ndarray) – The weights matrix.

• biases (ndarray | None) – The biases vector. All 0s if None.

• framework (str | None) – An optional framework hint (to figure out, e.g. whether to transpose torch weight matrices).

Returns:

The dense layer’s output.

Return type:

ndarray
