# PyTorch-Encoding | PyTorch版本 | fastpt版本 |PyTorch-Encoding版本 | DTK版本 | Python版本 | 推荐编译方式 |
| ----------- | ----------- | ----------- | ------------------------ | -----------------| ------------ |
| 2.5.1 | 2.1.0 |master | >= 25.04 | 3.8、3.10、3.11 | fastpt不转码 |
| 2.4.1 | 2.0.1 |master | >= 25.04 | 3.8、3.10、3.11 | fastpt不转码 |
| 其他 | 其他 | 其他 | 其他 | 3.8、3.10、3.11 | hip转码 |
created by [Hang Zhang](http://hangzh.com/) + pytorch版本大于2.4.1 && dtk版本大于25.04 推荐使用fastpt不转码编译。
## [Documentation](http://hangzh.com/PyTorch-Encoding/) ### 1、使用pip方式安装
PyTorch-Encoding whl包下载目录：[光和开发者社区](https://download.sourcefind.cn:65024/4/main)，选择对应的pytorch版本和python版本下载对应PyTorch-Encoding的whl包
- Please visit the [**Docs**](http://hangzh.com/PyTorch-Encoding/) for detail instructions of installation and usage. ```shell
pip install torch* (下载torch的whl包)
pip install fastpt* --no-deps (下载fastpt的whl包)
source /usr/local/bin/fastpt -E
pip install torch_encoding* (下载的PyTorch-Encoding的whl包)
```
### 2、使用源码编译方式安装
- Please visit the [link](http://hangzh.com/PyTorch-Encoding/model_zoo/imagenet.html) to image classification models. #### 编译环境准备
提供基于fastpt不转码编译：
- Please visit the [link](http://hangzh.com/PyTorch-Encoding/model_zoo/segmentation.html) to semantic segmentation models. 1. 基于光源pytorch基础镜像环境：镜像下载地址：[光合开发者社区](https://sourcefind.cn/#/image/dcu/pytorch)，根据pytorch、python、dtk及系统下载对应的镜像版本。
## Citations 2. 基于现有python环境：安装pytorch，fastpt whl包下载目录：[光合开发者社区](https://sourcefind.cn/#/image/dcu/pytorch)，根据python、dtk版本,下载对应pytorch的whl包。安装命令如下：
```shell
pip install torch* (下载torch的whl包)
pip install fastpt* --no-deps (下载fastpt的whl包, 安装顺序，先安装torch，后安装fastpt)
pip install pytest
pip install wheel
```
**ResNeSt: Split-Attention Networks** [[arXiv]](https://arxiv.org/abs/2004.08955) #### 源码编译安装
[Hang Zhang](http://hangzh.com/), Chongruo Wu, Zhongyue Zhang, Yi Zhu, Zhi Zhang, Haibin Lin, Yue Sun, Tong He, Jonas Muller, R. Manmatha, Mu Li and Alex Smola - 代码下载
```shell
git clone http://developer.sourcefind.cn/codes/OpenDAS/PyTorch-Encoding.git # 根据编译需要切换分支
``` ```
@article{zhang2020resnest, - 提供2种源码编译方式（进入PyTorch-Encoding目录）：
title={ResNeSt: Split-Attention Networks},
author={Zhang, Hang and Wu, Chongruo and Zhang, Zhongyue and Zhu, Yi and Zhang, Zhi and Lin, Haibin and Sun, Yue and He, Tong and Muller, Jonas and Manmatha, R. and Li, Mu and Smola, Alexander},
journal={arXiv preprint},
year={2020}
}
``` ```
1. 设置不转码编译环境变量
source /usr/local/bin/fastpt -C
**Context Encoding for Semantic Segmentation** [[arXiv]](https://arxiv.org/pdf/1803.08904.pdf) 2. 编译whl包并安装
[Hang Zhang](http://hangzh.com/), [Kristin Dana](http://eceweb1.rutgers.edu/vision/dana.html), [Jianping Shi](http://shijianping.me/), [Zhongyue Zhang](http://zhongyuezhang.com/), [Xiaogang Wang](http://www.ee.cuhk.edu.hk/~xgwang/), [Ambrish Tyagi](https://scholar.google.com/citations?user=GaSWCoUAAAAJ&hl=en), [Amit Agrawal](http://www.amitkagrawal.com/) python3 setup.py bdist_wheel
``` pip install dist/torch_encoding* --no-deps
@InProceedings{Zhang_2018_CVPR,
author = {Zhang, Hang and Dana, Kristin and Shi, Jianping and Zhang, Zhongyue and Wang, Xiaogang and Tyagi, Ambrish and Agrawal, Amit}, 3. 源码编译安装
title = {Context Encoding for Semantic Segmentation}, python3 setup.py install --no-deps
booktitle = {The IEEE Conference on Computer Vision and Pattern Recognition (CVPR)},
month = {June},
year = {2018}
}
``` ```
#### 注意事项
+ 若使用pip install下载安装过慢，可添加pypi清华源：-i https://pypi.tuna.tsinghua.edu.cn/simple/
+ ROCM_PATH为dtk的路径，默认为/opt/dtk
+ 在pytorch2.5.1环境下编译需要支持c++17语法，打开setup.py文件，把文件中的 -std=c++14 修改为 -std=c++17
