data3dprepare.py

师兄您好,请问您运行data3dprepare.py共花了多长时间呀?我按您的代码,运行3天了,最后崩在了第154-179个生成文件上面是不是我是不是哪里出了问题呀?暂时没改变您在data3dprepare.py里面写的参数

执行了3、4天的epoch是5吗?

抱歉,又来打扰了,我可能对工程做了点修改,根据现在的情况,感觉单卡训练5个epoch要3、4天;

因为5个epoch确实比着其他工程确实太少了,不太确定是不是我的修改有问题,下图(工程里的loss曲线时间是4天)的时间就是执行了5个epoch的时间吗?

假阳性减少

您好,我之前用luna16数据集已经进行了肺结节的检测,检测结果是假阳性高,想用您的假阳性减少这一模块来去假阳。我看到ResNet3d_train.py这代码里面涉及到nodel_all_train.csv这一文件,但是我没有找到这一文件。请问是不能直接用去假阳这一模块吗?还是有什么解决办法呢?谢谢,祝好!

GPU

Hello !
On what GPU did you run the training?
Thanks !

Ensembling both models for inference

Hello,

Thanks for sharing your work. Are the 2 models meant to ensemble, chain or otherwise combine in some way? I am wondering how you use the Resnet to reduce FP in the Vnet mask output. Thanks!

良恶性分类

您好,我阅读了您的文章并尝试了分类相关的程序,您提到的良恶性分类,然后实际上 0 代表非结节, 1 代表结节, 没有良恶性相关的区分,我有点困惑您提到的良恶性分类是如何做到的

良恶性分类

您好,感谢您的代码!但在运行分类代码的过程中遇到了无法生成分类文件0和1的问题,请问怎么解决?万分感激。

data3prepare.py

您好:
在data3prepare.py中,如果不想切出太多的sub_image,可以把numberxy=10, numberz=6
改成numberxy=3, numberz=20吗?

良恶 trainloss不下降

你好,我按照你的代码执行良恶数据处理后训练后loss一直在0.5-0.6几震荡,增加了epoch和BN层以及去除数据增强都没有作用,请问你在LUNA2022中得到的训练结果图是执行的这个代码吗?

测试结果的计算

很抱歉,再次打扰一下,想问一下工程里有关于测试结果统计的脚本吗?比如工程中的这个

Confusion_Matrix

module 'tensorflow' has no attribute 'placeholder'

When I am using this method:
Vnet3d = Vnet3dModule(128, 128, 16, channels=1, costname=("dice coefficient",), inference=True,
model_path="/content/drive/MyDrive/model/resnet.pd-50000.data-00000-of-00001")

I got this error:

in init(self, image_height, image_width, image_depth, channels, costname, inference, model_path)
195 self.channels = channels
196
--> 197 self.X = tf.placeholder("float", shape=[None, self.image_depth, self.image_height, self.image_width,
198 self.channels])
199 self.Y_gt = tf.placeholder("float", shape=[None, self.image_depth, self.image_height, self.image_width,

AttributeError: module 'tensorflow' has no attribute 'placeholder'

文件缺失

No such file or directory: 'dataprocess\data\nodel_all_train.csv'

运行的几点疑惑

你好,看过工程的readme,有几点疑惑希望能够得到解答;

1、中看过处理的9个步骤,我的理解是1~4重新生成了一次图片的掩膜文件和mhd中的坐标、和尺寸信息,根据luna官方给的数据是不是5~9才是必要的?

2、工程需要的tensorflow是那个版本,仅用GPU可以跑吗?

我想将其转为pytorch来实现,如果你感觉有什么建议或者要注意的,希望可以指教一下,拜谢!

Augmain.py file is not executing

Dear Sir, your work is helped me a lot in that I'm facing following problem,
please suggest how to run Augmain.py in spyder. when I run it showing following error:

File "D:\mywork\LUNA16 Master\Augmain.py", line 1, in
from dataaugmentation.Augmentation.ImageAugmentation import DataAug3D

ModuleNotFoundError: No module named 'dataaugmentation'

So, please provide the solution for above problem.

thank for advance

关于data3dprepare

你好,正在学习相关内容,想问一下data3dprepare是如何获取(96,96,16)的patch的训练数据的
该模型是否可以在原图而不是子图预测出mask

Citation missing!

Hello, it would be helpful if the paper presenting the work in this repo be cited here for reference.

Any elaboration would be much appreciated :) thanks in advance.

Vnet模型训练的问题

你好,我是一个初学者。在复现您的代码的时候,出现了一些问题,在训练Vnet模型时训练时间很短就结束了,Training_loss为-0.07308,请问可以给我一些建议吗。 还有一个疑问为什么要令Training_accuracy=-training_loss

about the dataprcessing

陈老师,你好
我运行数据预处理部分的LUNA_node_extraction.py时,本来应该是生成classification文件夹的,但是我运行后没有结果。调试了一下代码发现line 93处的 if mini_df.shape[0] > 0: 这个判断都没有进去。尝试在此之前添加了一句print(mini_df.shape[0]),发现全部都是零。
多谢老师指教

数据集csv文件生成

您好,感谢您的代码。有几个问题我想请教,希望您不吝赐教!
首先是请问这几个数据子集是在哪段代码生成的,我好像并没有找到
image
其次是这两步都是运行utils.py吗?以及要存储分类数据的话,运行完LUNA_node_extraction.py要紧接着运行utils吗?
image
由于学识尚浅,希望您能帮我解答以便我更好的理解您的代码,谢谢🙏

关于模型检测的问题

我发现,如果我用全黑或者全白的图片放入您的V-net中进行检测,结果却显示有结节,这显然是不科学的,但我并不知道有什么问题,不知道您有尝试过吗?

How to test a complete 3D image?

I want to know how can we test a complete 3D image? If I have a 3D image (512512300), how to generate the nodule? Is there a such test code?
In addition, how to generate the confusion matrix and metrics?

关于dice loss

您好,我复现了您的程序,觉得很有收获,只是有一个疑问就是您的loss = -dice,我觉得这里应该是1-dice。祝好。

Prediction result

I have trained your models. The results are good by your way.
But when I tested on dataset without segmentation techniques. The results for nodule class(label = 1) is very poor.
Do you think about it ? the test set should not be augmented.

I also want to download your trained models, but it is impossible with foreigners.
Why you do not upload on github ??

Thank you very much

How to run Step 4

Hello, when you run your program, you encounter some doubts. When I finished running Parts 1-3, I encountered difficulties in running Part 4. I don't know how to save the generated mask to the CSV file. Do you need to write your own code, or which Python file do you want to run? I hope to get your help.
Thank you.

Mis-matching Total number of candidates

Hello,

after evaluating the predictions file (i.e. METU_VISION_FPRED.csv) using the LUNA16 official script (i.e. noduleCADEvaluationLUNA16.py), I get an output (CADAnalysis.txt) like this :

CADAnalysis.txt

CAD Analysis: METU_VISION_FPRED

Candidate detection results:
True positives: 1128
False positives: 81706
False negatives: 58
True negatives: 0
Total number of candidates: 87794
Total number of nodules: 1186
Ignored candidates on excluded nodules: 4600
Ignored candidates which were double detections on a nodule: 360
Sensitivity: 0.951096121
Average number of candidates per scan: 98.867117117

From what I understand, the the Total number of candidates should be 754,975 according to https://luna16.grand-challenge.org/Evaluation/

Even though METU_VISION_FPRED.csv has 754,975 candidates!! the CADAnalysis.txt still says Total number of candidates: 87794 !!!!!

Looking forward to hearing back from you. Any help is extremely appreciated.

Many thanks.

Any idea why that happens?? Am I missing something?

结节假阳性二分类数据划分

请问在肺结节假阳性二分类的时候,代码结果是采用的了全部的结节数据集吗?因为我看到这个任务的正样本有1300+而负样本有5'000'000+

subset.py的一些疑惑?

您好!正在复现您项目的分类部分,遇到了点问题,不是很理解subset.py文件的运行机理,
具体是里面的sys.argv[1]所对应的文件是什么?望解惑!感谢

数据集问题

您好,请问您的原始数据是怎么存放的,可以给出您数据的目录吗?

issue with Vnet Train

Dear Sir thanks for your post it helped a lot. But I'm getting following issue when executing Vnet Training:

from Vnet.model_vnet3d import Vnet3dModule

ModuleNotFoundError: No module named 'Vnet'

I'm using Anacond in Windows.

So please suggest the solution for above issue

更新后data3dprepare.py异常

师兄您好,这几天我运行了一下您的程序,发现您更新了data3dprepare.py,但运行到
hr_samples[0, 0:blockz, 0:block_width, 0:block_height] = image[0:rangz, 0:rangwidth, 0:rangheight]
的时候报错,
TypeError: slice indices must be integers or None or have an index method
然后我发现rangz rangwidth rangheight 在前几行的计算过程得出的貌似不是整数型,
rangz = lambda imagez, blockz: imagez if imagez < blockz else blockz
rangwidth = lambda width, block_width: width if width < block_width else block_width
rangheight = lambda height, block_height: height if width < block_height else block_height
您看这里是不是需要int强制转换一下???
