活動地址：CSDN21天學習挑戰賽

1.環境要求

• BasicSR官方網站
• Python >= 3.7 (推薦使用 Anaconda 或 Miniconda)
• PyTorch >= 1.3
• NVIDIA GPU + CUDA

2.Python3.8

小於3.7version cannot be installedBasicSR,It will report that there is no corresponding version

• 在anaconda中創建一個python3.8的環境

3.pytorch

BasicSR是基於pytorch的包,不安裝pytorch直接安裝BasicSR會報錯如下

ERROR: Command errored out with exit status 1:

• 安裝pytorch:耗時較久,大概一兩個小時

pip3 install torch

4. 安裝BasicSR

• pip安裝：

pip3 install basicsr

5.查看是否成功

• 進入python

python

• 導入torch

import torch

• 導入BasicSR

import bascisr

• 發生報錯：

ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.

• 解決方法：
  • 使用指令先看下目前都有哪些版本的strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX
  • found only to3.3版本：
    GLIBCXX_3.4 GLIBCXX_3.4.1 GLIBCXX_3.4.2 GLIBCXX_3.4.3 GLIBCXX_3.4.4 GLIBCXX_3.4.5 GLIBCXX_3.4.6 GLIBCXX_3.4.7 GLIBCXX_3.4.8 GLIBCXX_3.4.9 GLIBCXX_3.4.10 GLIBCXX_3.4.11 GLIBCXX_3.4.12 GLIBCXX_3.4.13 GLIBCXX_3.4.14 GLIBCXX_3.4.15 GLIBCXX_3.4.16 GLIBCXX_3.4.17 GLIBCXX_3.4.18 GLIBCXX_3.4.19 GLIBCXX_3.4.20 GLIBCXX_3.4.21 GLIBCXX_DEBUG_MESSAGE_LENGTH
  • View other files of the same type in the current systemsudo find -name "libstdc++.so.6*“
  • 結果如下：

  • 選了一個版本較高的使用之前的指令看看其是否包含需要的版本
    strings ./anaconda3/pkgs/libstdcxx-ng-9.3.0-hd4cf53a_17/lib/libstdc++.so.6.0.28 | grep GLIBCXX
  • The required version was found,復制鏈接sudo cp ./anaconda3/pkgs/libstdcxx-ng-9.3.0-hd4cf53a_17/lib/libstdc++.so.6.0.28 /usr/lib/x86_64-linux-gnu
  • Remove previous linksudo rm /usr/lib/x86_64-linux-gnu/libstdc++.so.6
  • 創建新的鏈接sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.28 /usr/lib/x86_64-linux-gnu/libstdc++.so.6

6.完成
