Pred pred.float
WebApr 7, 2024 · I'm looking for a nice way to sequentially combine two itertools operators. As an example, suppose we want to select numbers from a generator sequence less than a threshold, after having gotten past that threshold. For a threshold of 12000, these would correspond to it.takewhile (lambda x: x<12000) and it.takewhile (lambda x: x>=12000): # … WebFeb 19, 2024 · Assertions Reference.

WebReturns the indices of the maximum values of a tensor across a dimension. This is the second value returned by torch.max (). See its documentation for the exact semantics of this method. Parameters: input ( Tensor) – the input tensor. dim ( int) – the dimension to reduce. If None, the argmax of the flattened input is returned.

WebApr 15, 2024 · Hi, I used multi-hot labeling for the multi-label cls problem. Initially I was using BCEWithLogitsLoss but as the dataset set is quite imbalanced, it soon predicts all 0. I have tried focal loss as following but the model just does not converge. Is there any suggestion? def focal_loss(self, pred, gt): ''' Modified focal loss. Exactly the same as CornerNet.
