RuntimeError: stack expects each tensor to be equal size, but got [4] at entry 0 and [5] at entry 7

你可以检查一下文件夹里的图片,是否都是RGB图片,尺寸是否一致。
如果不一致,你需要手动写一个 collate 函数,对尺寸不一致的图片进行一个补全操作(padding)。
比如先创建一个 (batch_size, height, max_width, 3) 的矩阵,然后将每张图贴进去。

已解决 谢谢大佬

大佬您好,为什么我检查了我图片尺寸都是一样的(3x70x200),还是出现了这种问题呢?以及collate_fn函数具体要怎么操作啊

我是训练效果很差。。。
