Returns the total number of elements in the input tensor. Parameters input (Tensor)– the input tensor. Example: 代码语言:javascript 复制 >>> a = torch.randn(1, 2, 3, 4, 5) >>> torch.numel(a) 120 >>> a = torch.zeros(4,4) >>> torch.numel(a) 16 ...
{}) RuntimeError: The tensor has a non-zero number of elements, but its data is not allocated yet. Caffe2 uses a lazy allocation, so you will need to call mutable_data() or raw_ mutable_data() to actually allocate memory. The above exception was the direct cause of the following ...
