0.前言

        ubuntu18.04  cpu版本  pytorch

1.配置环境

        选择python3.6版本进行配置，利用anaconda创建python=3.6的环境fcn,参考：https://github.com/wkentaro/pytorch-fcnhttps://github.com/wkentaro/pytorch-fcn

• pytorch >= 0.2.0
• torchvision >= 0.1.8
• fcn >= 6.1.5
• Pillow
• scipy
• tqdm

1.1 安装fcn包：

pip install fcn
#pip install --default-timeout=100 -i https://pypi.tuna.tsinghua.edu.cn/simple fcn

1.2 安装PyTorch：

        进入PyTorch官网，下载cpu版本：

Start Locally | PyTorchhttps://pytorch.org/get-started/locally/

        复制网页的命令，我的如下： 

conda install pytorch torchvision torchaudio cpuonly -c pytorch

#或者pip
pip3 install torch==1.10.2+cpu torchvision==0.11.3+cpu torchaudio==0.10.2+cpu -f https://download.pytorch.org/whl/cpu/torch_stable.html

         验证安装：

 clash$ conda activate py36
(py36)  clash$ python
Python 3.6.13 |Anaconda, Inc.| (default, Jun  4 2021, 14:25:59) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
>>> torch.cuda.is_available()
False
>>> 

1.3 安装pillow、scipy、tqdm

pip install pillow
pip install scipy
pip install tqdm

1.4 验证环境配置

      下载 https://github.com/wkentaro/pytorch-fcnhttps://github.com/wkentaro/pytorch-fcn 的代码并解压,pip install .后出现下面一堆successfully。

(py36)  paper1$ cd pytorch-fcn-main/
(py36)  pytorch-fcn-main$ pip install .     ######安装torchfcn

2.利用VOC数据集训练example

        正在下载数据集-----很慢----不知有没有快的方法
