When I run the code, it will break down sometimes.

Hi, did you solve that problem?

I think it is because of the data. If you train the model with few images, say the first 100 images, you can run the code without any problems.

Thanks，I have tried to increment the number of training samples and remove the wrong samples, and finally the code can run.

Hi,I met this problem too.I adjusted the dataset, but I still had this problem during training.can you tell me how to deal with the training data in detail?thank you!

你好请问这个问题最后得到解决了吗？我也有这个问题啊

这个问题我这边是解决了，所以发在这里
造成这个bug的主要原因就是数据的问题，real_input那个变量无法读取数据，所以运行时这个变量的值时nan，表示为空
解决办法：寻找数据集的存储路径，imageset_dir后面的路径是否正确注意要使用“/”不要用“\”，使用正确的路径之后就可以real_input就会有值了。

按照您说的方法，代码成功跑起来了，非常感谢。但是在epoch1_40的时候，在这报错又出现了，请问您有遇到吗？

EdwardBao1006 · 2023-03-04T09:14:58Z

如果直接删除破损图像，还是会报错，我是先删除了破损照片，然后对数据集里面的图像重新编号和命名，但是删除的时候一定要成对删除，image+mask，我用的代码如下，记住每次删除图像以后都要重新运行这个程序编号一下。

rename.py

import os
root_path = "./training"
filelist = os.listdir(root_path)

filelist.sort()
total_num = len(filelist)
i = 0
j = 0
for item in filelist:
    if item.endswith("_1.png"):
        src = os.path.join(os.path.abspath(root_path), item)
        s = str(i)
        s = s.zfill(6)  # 保留几位
        dst = os.path.join(os.path.abspath(root_path), s + '_1.png')

        try:
            os.rename(src, dst)
            print ('converting %s to %s ...' % (src, dst))
            i = i + 1
        except:
            continue

    if item.endswith("_2.png"):
        src = os.path.join(os.path.abspath(root_path), item)
        s = str(j)
        s = s.zfill(6)
        dst = os.path.join(os.path.abspath(root_path), s + '_2.png')

        try:
            os.rename(src, dst)
            print ('converting %s to %s ...' % (src, dst))
            j = j + 1
        except:
            continue

希望能帮上忙。
