一、安装配置环境
1、准备工作
代码地址
GitHub - bubbliiiing/classification-pytorch: 这是各个主干网络分类模型的源码，可以用于训练自己的分类模型。
# 创建环境
conda create -n ptorch1_2_0 python=3.6
# 然后启动
conda install pytorch==1.2.0 torchvision==0.4.0 cudatoolkit=10.0 -c pytorch
pip install scipy==1.2.1 numpy==1.17.0 matplotlib==3.1.2 opencv_python==4.1.2.30 tqdm==4.60.0 Pillow==8.2.0 h5py==2.10.0
下载好后 他的那个数据集 按他那个配置，然后在项目根目录下运行
python txt_annotation.py 生成对应的 txt 文件
2、遇到的问题
1、
ImportError: TensorBoard logging requires TensorBoard with Python summary writer installed. This should be available in 1.14 or above.解决
pip install tensorboard2、
ModuleNotFoundError: No module named 'past'解决办法
pip install future3、
ImportError: libSM.so.6: cannot open shared object file: No such file or directory
# 和
ImportError: libXrender.so.1: cannot open shared object file: No such file or directory解决
apt-get install libsm6
apt-get install libxrender1二、debug 记录
1、train_lines
val_lines
2、 show_config

三、其它
1、打印模型 model， 这个应该是 backbone
