csguoh/MambaIR: [ECCV2024, CVPR2025] MambaIR and MambaIRv2!

一开始直接输入命令

conda env create -f environment.yaml

安装了半天爆出来好几个错误，其中一个是没有nvcc

输入以下命令：

module avail

 发现没有对应的cuda11.7的版本

就安装cuda11.7的

然后输入以下命令激活环境：

 source /data/home/sczc338/run/soft/cuda11.7/env.sh

 把这个问题解决了

具体的可以看一下这篇文章：

.whl文件-CSDN博客

里面有如何在超算上安装相应cuda版本的详细步骤 

还有一个是什么包找不到好像是。

因为这里默认安装包从defaults通道，但这里的包实际上更新比较慢，所以我使用了如下命令让conda-forge通道为优先级最高的通道（conda-forge是社区驱动的，更新包较快）（conda-forge is a community effort that provides conda packages for a wide range of software.）

• Make sure you have conda >=4.9:

  conda --version
  conda update conda
  

• Add conda-forge as the highest priority channel:

  conda config --add channels conda-forge
  

• Activate strict channel priority (strict will be activated by default in conda 5.0):

  conda config --set channel_priority strict

然后还爆出了一堆的问题，解决着解决着，发现我这个mambair环境竟然用的是python3.8的版本，但是安装的东西都是基于python3.9的。（包括the mamba_ssm library）

我想输入以下命令来更改环境的python版本，但是报错啦，不知道什么原因

conda install python=3.9

输入以下命令查看python版本：

python --version

所以我把现有的mambair环境删了，再重新创一个 

conda create -n mambair python=3.9

此时如果再运行命令：

conda env create -f environment.yaml

 就会报出mambair环境已存在的错误，所以使用以下命令：

(mambair) sczc338@ln01:~/run/MambaIR$ conda env update -f environment.yaml

报出如下错误：

主要注意这句话： ModuleNotFoundError: No module named 'packaging'

所以：

conda install packaging

再输入命令：

conda env update -f environment.yaml

 报错啦

hh应该是因为我没有启动cuda环境回去再弄。

输入：

 source /data/home/sczc338/run/soft/cuda11.7/env.sh

再输入：

conda env update -f environment.yaml

然后就成功了！！！
