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

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

Parameters:

  • x – The input to the dense layer.

  • weights – The weights matrix.

  • biases – The biases vector. All 0s if None.

  • framework – An optional framework hint (to figure out, e.g. whether to transpose torch weight matrices).

Returns:

The dense layer’s output.
