安装之前可以先了解一下论文的主要内容，便于之后网络训练与推理，调试程序。

论文地址：nnU-Net: a self-configuring method for deep learning-based biomedical image segmentation | Nature Methods

也可以从其他博客快速浏览：论文解读- nnU-Net: Self-adapting Framework for U-Net-Based Medical Image Segmentation（附实现教程）_nnunet self adaptinng-CSDN博客

如果想跟官网github一样在ubuntu下安装参考：nnUNet保姆级使用教程！从环境配置到训练与推理（新手必看）-CSDN博客

1.本博客是在win11安装，前期Anaconda的虚拟环境自己配置好，然后下载好nnUnet v1的安装包，然后解压在该目中运行：

pip install -e .

如果需要观察模型的网络结构图可以安装hiddenlayer:

nnUNet给出的指令：

pip install --upgrade git+https://github.com/FabianIsensee/hiddenlayer.git@more_plotted_details#egg=hiddenlayer

上面指令自己运行报错:

× git clone --filter=blob:none --quiet https://github.com/FabianIsensee/hiddenlayer.git 'C:\Users\Administrator\AppData\Local\Temp\pip-install-dh84s7ac\hiddenlayer_be2e7545caf44fbeae10f5b0cfd81e30' did not run successfully，可能是网络原因。干脆直接从hiddenlayer官网的指令进行安装（顺利安装）:

pip install git+https://github.com/waleedka/hiddenlayer.git

2.开始准备推理的数据，注意它的格式要求，开始体验一下如何用官网模型进行infer使用：

查看nnUNet提供的预训练好的模型：

需要类似于ubuntu系统下一样，设置环境临时变量：

set RESULTS_FOLDER=自己的硬盘根目录\nnUNet-nnunetv1\dataset\nnUNet_trained_models
set nnUNet_raw_data_base=自己的硬盘根目录\nnUNet-nnunetv1\dataset\nnUNet_raw
set nnUNet_preprocessed=自己的硬盘根目录\nnUNet-nnunetv1\dataset\nnUNet_preprocessed是否设置成功，可以通过
echo %RESULTS_FOLDER%
echo %nnUNet_raw_data_base%
echo %nnUNet_preprocessed%

3. 推理之前需要将数据按照nnUNet要求进行格式转换：

由于ubuntu跟win11系统路径格式不一样(不懂可以看下区别)，需要提前修改相应的程序：

1）nnUNet_convert_decathlon_task.py中22行的“folder.split('/')[-1]”改成“folder.split('\\')[-1]”。

2）utils.py中40行的input_folder.split("/")[-1]改成input_folder.split("\\")[-1]

3) common_utils.py中26行的filename.split("/")[-1]改成filename.split("\\")[-1]

然后，根据数据格式转换说明：

nnUNet_convert_decathlon_task -i FOLDER_TO_TASK_AS_DOWNLOADED_FROM_MSD -p NUM_PROCESSES

具体指令：

nnUNet_convert_decathlon_task -i 自己存放数据集的路径\Task05_Prostate

运行结果目录如下：

以imagesTs为例：

按照官网进行数据预处理：

nnUNet_plan_and_preprocess -t XXX --verify_dataset_integrity

XXX表示任务号；

nnUNet_plan_and_preprocess -t 005 --verify_dataset_integrity

4. 运行推理程序：

范例：
nnUNet_predict -i INPUT_FOLDER -o OUTPUT_FOLDER -t TASK_NAME_OR_ID 
-m CONFIGURATION --save_npz

这里需要注意一定要修改cropping.py中123行的i.split("/")[-1][:-4]，将其修改为i.split("\\")[-1][:-4]。否则会报错误（这个错误很隐蔽，网上查了很多资料没有解决，一句句打断点找到的问题所在，debug不易，趟掉很多坑）：

“return _nx.concatenate(arrs, 0, dtype=dtype, casting=casting)
ValueError: need at least one array to concatenate”

检测一下nnUNet_cropped_data是否生成了预处理的文件（*.npz和*.pkl）:

nnUNet_predict -i 自己的路径\nnUNet_raw\nnUNet_raw_data\Task005_Prostate\imagesTs -o 自己的路径\nnUNet_raw\nnUNet_raw_data\Task005_Prostate\inferTs -t 5 -m 3d_fullres -f 0

运行结果：
