gradients(of:with:name:)
Calculates a partial derivative of primaryTensor with respect to the tensors.
Declaration
func gradients(of primaryTensor: MPSGraphTensor, with tensors: [MPSGraphTensor], name: String?) -> [MPSGraphTensor : MPSGraphTensor]Parameters
- primaryTensor:
Tensor to be differentiated (numerator).
- tensors:
Tensors to do the differentiation with (denominator).
- name:
Name for the gradient operation.
Return Value
A valid MPSGraphTensor dictionary object containing partial derivative d(primaryTensor)/d(secondaryTensor) for each tensor as key.
