如何解决RuntimeError: invalid argument 5: k not in range for dimension

Question

RuntimeError: invalid argument 5: k not in range for dimension at C:/w/b/windows/pytorch/aten/src\THC/generic/THCTensorTopK.cu:24

在调用DGCNN函数时
knn出现报错

def knn(x, k):
    inner = -2 * torch.matmul(x.transpose(2, 1).contiguous(), x)
    xx = torch.sum(x ** 2, dim=1, keepdim=True)
    distance = -xx - inner - xx.transpose(2, 1).contiguous()
    idx = distance.topk( k=k, dim=-1)[1]     # 此处出现报错
    return idx

尝试解决但都没有效果，求问解决方法

你是几分类，报错说是参数5无效，分类数达不到5就会报错
