判断Numpy.ndarray/PyTorch张量是否为空

判断Numpy.ndarray是否为空

#bboxes是ndarray类型
if bboxes.size > 0:
    print('ndarray bboxes is not empty')
else:
    print('ndarray bboxes is empty')

判断PyTorch中张量是否为空

import torch 
#data是tensor张量
if data.numel() > 0:
    print('tensor data is not empty')
else:
    print('tensor data is empty')
