性能情况

unet并不适合VOC此类数据集，其更适合特征少，需要浅层特征的医药数据集之类的。

训练数据集 权值文件名称 测试数据集 输入图片大小 mIOU
VOC12+SBD unet_voc.pth VOC-Val12 512x512 55.11

所需环境

torch==1.2.0
torchvision==0.4.0

注意事项

unet_voc.pth是基于VOC拓展数据集训练的。
unet_medical.pth是使用示例的细胞分割数据集训练的。
在使用时需要注意区分。

文件下载

训练所需的unet_voc.pth和unet_medical.pth可在百度网盘中下载。

VOC拓展数据集的百度网盘如下：

预测步骤

一、使用预训练权重

a、VOC预训练权重

  1. 下载完库后解压，如果想要利用voc训练好的权重进行预测，在百度网盘或者release下载unet_voc.pth，放入model_data，运行即可预测。

  1. 利用video.py可进行摄像头检测。

b、医药预训练权重

  1. 下载完库后解压，如果想要利用医药数据集训练好的权重进行预测，在百度网盘或者release下载unet_medical.pth，放入model_data，修改unet.py中的model_path和num_classes；
_defaults = {
    "model_path"        : 'model_data/unet_voc.pth',
    "model_image_size"  : (512, 512, 3),
    "num_classes"       : 21,
    "cuda"              : True,
    #--------------------------------#
    #   blend参数用于控制是否
    #   让识别结果和原图混合
    #--------------------------------#
    "blend"             : True
}
  1. 运行即可预测。

二、使用自己训练的权重

  1. 按照训练步骤训练。
  2. 在unet.py文件里面，在如下部分修改model_path、backbone和num_classes使其对应训练好的文件；model_path对应logs文件夹下面的权值文件。
_defaults = {
    "model_path"        : 'model_data/unet_voc.pth',
    "model_image_size"  : (512, 512, 3),
    "num_classes"       : 21,
    "cuda"              : True,
    #--------------------------------#
    #   blend参数用于控制是否
    #   让识别结果和原图混合
    #--------------------------------#
    "blend"             : True
}
  1. 运行predict.py，输入
img/street.jpg
  1. 利用video.py可进行摄像头检测。

训练步骤

一、训练voc数据集

  1. 将我提供的voc数据集放入VOCdevkit中（无需运行voc2unet.py）。
  2. 在train.py中设置对应参数，默认参数已经对应voc数据集所需要的参数了，所以只要修改backbone和model_path即可。
  3. 运行train.py进行训练。

二、训练自己的数据集

  1. 本文使用VOC格式进行训练。
  2. 训练前将标签文件放在VOCdevkit文件夹下的VOC2007文件夹下的SegmentationClass中。
  3. 训练前将图片文件放在VOCdevkit文件夹下的VOC2007文件夹下的JPEGImages中。
  4. 在训练前利用voc2unet.py文件生成对应的txt。
  5. 注意修改train.py的num_classes为分类个数+1。
  6. 运行train.py即可开始训练。

三、训练医药数据集

  1. 下载VGG的预训练权重到model_data下面。
  2. 按照默认参数运行train_medical.py即可开始训练。

    询问一下预训练的问题

    你好，打扰了。我是想问下主干模型是指的是在下采样过程中使用的vgg吗？如果我不改变上采样是不是就不用使用imagenet训练。然后注销掉model_path=‘’ 以及 if model_path !=‘’这段。然后使用自己的数据集去进行训练。 谢谢大佬！！！！！！。实际上大佬你的voc的权重文件是不是为二次预训练的数据。 不好意思，语言表达能力不行。俺不晓得这样说大佬明不明白。

  • 训练一段时间后，CE loss变为NAN

    训练一段时间后，CE loss变为NAN

    您好，看了您的教程我试着自己搭建了一个U-Net模型，并采用Dice + CE loss作为损失函数，但在迭代几十个epoch后，我的CE loss返回了NAN值，反馈的结果是 ‘Function 'LogSoftmaxBackward' returned nan values in its 0th output.’ 同样的数据在您源码上运行没有出现这个问题，请问您是否知道些解决方法？

  • 为啥在dataloader第40行转换的array的shape和cv2不一样呢

    为啥在dataloader第40行转换的array的shape和cv2不一样呢

    我使用json_to_dataset.py转化mask后尝试使用代码查看shape import cv2 import numpy as np from PIL import Image

    file = '/home/fut/Downloads/unet-pytorch-main/mydata/masks/ID_1110_json.png' img = cv2.imread(file, cv2.IMREAD_UNCHANGED) print(img.shape)

    pil = Image.open(file) img2 = np.array(pil) print(img2.shape) 结果会是： (800, 800, 3) (800, 800) 为什么PIL读取后通道就没了，正是因为这个原因你的项目会很好跑起来。
