数据集使用的是省肿瘤项目当中的病理数据集(.svs文件)。(也可用公开的camyon16数据集)
.svs图像存储位置:
/data/Colon/svs
切割并提取特征后的存储位置:
data/data_seg_patch
data/feat_dir
注:实际处理时切割并提取特征后的存储位置存在了整个code的上一级目录中。
Mostly folked from CLAM, with minor modification. So just follow the docs to perform baseline, or with following steps:
1.Preparing grid patches of WSI without overlap.
bash create_patches.sh
2.Preparing pretrained patch features fow WSI head training.
bash create_feature.sh
此处原始代码仓直接搬用CLAM的预处理病理图像和提取特征的代码(写了两个脚本),但并没有指明要修改哪些参数,可参照http://gitlab.nju.rl/nju/szl_pathology中的README.md文件准备数据集并修改超参数。
针对省肿瘤病理数据集,有备份的已经过CLAM提取特征后的图像(存在nju云盘中,13.4G),可直接下载用来处理。
原始代码仓还漏写了划分数据集的步骤,本代码中补充了这一步骤:
python3 create_splits.py
CUDA_VISIBLE_DEVICES=2 python3 extract_topK_ROIs.py --data_h5_dir ../data_seg_patch --csv_path ../data_seg_patch/process_list_autogen.csv --feat_dir ../feat_dir --patch_dir ../data_seg_patch --data_slide_dir data --batch_size 512 --slide_ext .svs
CUDA:11.6
创建新环境
conda create --name p39 python=3.9
激活
conda activate p39
安装依赖项
pip install -r ./requirments.txt
下载GPU版本的pytorch(CUDA版本=11.6),2G左右,较快。
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu116
验证torch是否安装成功
import torch
print(torch.__version__)
print(torch.version.cuda)
如果遇到topk
的module found error
报错:
git clone https://github.com/oval-group/smooth-topk.git
cd smooth-topk
python setup.py install#此处报错则替换为 pip install .
base中装载了2.0.1的cpu版本的pytorch,new_env中安装GPU版pytorch成功
注:环境里用pip
安装,如果安装到了外面的python
里,在pip
指令前加一个python -m
python -m pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu116
bash scripts/train.sh
训练过程中截图:
最优模型:
训练集上的准确率达到了97.62%
Epoch: 47, train_loss: 0.2090, train_clustering_loss: 0.0592, train_error: 0.0238
bash scripts/vib_train.sh
- Collecting top-k patches of WSI by inference vib model, save in pt form.
bash scripts/extract_topk_rois.sh
- Perform end-to-end training.
bash scripts/e2e_train.sh
Now you can use finetuned patch bakcbone in stage-2 to generate patch features, then run stage-1 again with the new features.
同CLAM框架的结果格式,此图显示了5折交叉的测试结果
验证集和测试集的最高准确率达到了1和0.733。
