Webtorch.Tensor.backward. Tensor.backward(gradient=None, retain_graph=None, create_graph=False, inputs=None)[source] Computes the gradient of current tensor w.r.t. graph leaves. The graph is differentiated using the chain rule. If the tensor is non-scalar (i.e. its data has more than one element) and requires gradient, the function additionally ... WebThis fails for the same reason as: import numpy as np arr = np.array ( [1.0, 2.0, 3.0], dtype=object) np.sin (arr) # AttributeError: 'float' object has no attribute 'sin'. When np.sin is called on an object array, it tries to call the sin method of each element. If you know the dtype of θr.values, you can fix this with:
