在docker 训练新环境中mmclassification装包遇见的一些问题

项目场景：

python 3.6.9

已经安装sudo

现在要安装一些包

 镜像是学长配的tensortrt8 容器是自己提的

问题描述

在MMlab里运行命令

python mmlab/mmclassification/tools/train.py mmlab/mmclassification/configs/tutorial/resnet50_finetune_cifar.py

问题1：发现 ModuleNotFoundError: No module named 'mmcv' 

root@407d147d301b:/# python mmlab/mmclassification/tools/train.py mmlab/mmclassification/configs/tutorial/resnet50_finetune_cifar.py
Traceback (most recent call last):
  File "mmlab/mmclassification/tools/train.py", line 9, in <module>
    import mmcv
ModuleNotFoundError: No module named 'mmcv'

 问题2：”想使用pip下载 mmcv,发现pip没有

root@407d147d301b:/# pip install mmcv-full
bash: pip: command not found

 问题3：下载pip后发现找不到pip

root@407d147d301b:/# sudo apt install python3-pip
Reading package lists... Done

root@407d147d301b:/# pip --version
bash: pip: command not found

 

先下载pip 使用sudo    （下载sudo）上篇文章 有链接

root@407d147d301b:/# sudo apt-get install python3-pip

问题3解决方法：下载pip后发现找不到pip,解决办法：

 您可以使用python3 -m pip作为pip的同义词，解决了麻烦

问题4：解决后执行 出现新问题

 ModuleNotFoundError: No module named 'skbuild'

pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple scikit-build

问题5 执行 python3 -m pip install mmcv-full 后显示

Running setup.py bdist_wheel for opencv-python ... -一直卡着不动

Running setup.py bdist_wheel for opencv-python ... -

 问题5 解决办法升级Pip 指令

pip3 install --upgrade pip

oot@407d147d301b:/# pip3 install --upgrade pip

 继续执行 python3 -m pip install mmcv-full，成功 现在下好了mmcv包

root@407d147d301b:/# python3 -m pip install mmcv-full
Collecting mmcv-full

  P~~~~~~~~~~

 执行训练语句

python mmlab/mmclassification/tools/train.py mmlab/mmclassification/configs/tutorial/resnet50_finetune_cifar.py

 出现问题6  ModuleNotFoundError: No module named 'torch' 没有torch包

简单了 用pip下载即可

继续执行训练语句

问题7：ModuleNotFoundError: No module named 'torchvision'没有torchvision包

用pip install torchvision 下载成功

root@407d147d301b:/# pip install torchvision    
Uninstalling torch-1.10.2:
      Successfully uninstalled torch-1.10.2

问题8： ModuleNotFoundError: No module named 'mmcls' 没有mmcls包

pip install mmcls 下载解决

root@407d147d301b:/# pip install mmcls
Collecting mmcls           
 mmcls
Successfully installed cycler-0.11.0 kiwisolver-1.3.1 matplotlib-3.3.4 mmcls-0.24.0 python-dateutil-2.8.2

 继续执行训练语句

问题9：AttributeError: 'ConfigDict' object has no attribute 'data'

意思是加载程序 ：属性错误：“字典”对象没有属性“数据” 

看来包的问题解决的差不多了 问题9 现在是结构问题了   以后接着搞
