Did you know?
WebOur solution is that BCELoss clamps its log function outputs to be greater than or equal to -100. This way, we can always have a finite loss value and a linear backward method. Parameters: weight ( Tensor, optional) – a manual rescaling weight given to the loss of each batch element. If given, has to be a Tensor of size nbatch. WebJul 2, 2024 · As pointed out by warren-weckesser this can also happen if you use dtype object (and in fact this is likelier the issue you are facing): >>> s = pd.Series([1.0], dtype='object') >>> s 0 1 dtype: object >>> np.log(s) Traceback (most recent call last): File "", line 1, in AttributeError: 'float' object has no attribute 'log'
