Summary< span>:

From the above three methods, we can see that the operating system is Raspbian 10 buster, with this information, you can perform subsequent source changes.

Change source

You can refer to the help of Tsinghua website: https://mirrors.tuna.tsinghua.edu.cn/help/raspbian/

Enter the above website;
in In the Instructions column, select the version of the Raspberry Pi operating system that was previously queried, for example mine is Debian 10;
- < p class="md-end-block">Don’t choose the wrong version!

Edit/etc/apt/sources.listfile, modify the content to:

deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/ raspbian/ buster main non-free contrib

deb-src http://mirrors.tuna.tsinghua.edu.cn/raspbian /raspbian/ buster main non-free contrib

Use the original content with #+spaceComment it out

Edit the /etc/apt/sources.list.d/raspi.list file and modify the content Is:
```
deb http:// mirrors.tuna.tsinghua.edu.cn/raspberrypi/ buster main ui
```
After editing the mirror station, use the sudo apt-get update command to update the software source list , And check that the editing just now is correct.

Anaconda change source< /h3>

Refer to the help of Tsinghua Station: https://mirrors.tuna.tsinghua.edu.cn/help/ anaconda/

Find the .condarcfile in the user directory:
- Windows users cannot directly create the name .condarc file, can be executed in Anaconda Prompt conda config --set show_channel_urls yes Generate the file and then modify it

Modify its content to:

channels:

 - defaults

show_channel_urls: true

default_channels:

 - https://mirrors.tuna.tsinghua.edu.cn /anaconda/pkgs/main

-https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs /free

-https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs /r

custom_channels: # This part of the content needs to be added, and generally does not need to be added

 conda-forge: https://mirrors.tuna.tsinghua. edu.cn/anaconda/cloud

 msys2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/ cloud

 bioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/ cloud

 pytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/ cloud

 simpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/ cloud

If you want to restore the source, then By entering the command: conda config --remove-key channelsSimply

PIP/PIP3 replacement source

Upgrade pip

It is recommended to upgrade pip to pip3 here. The command used is: python -m pip install --upgrade pip< /p>

Refer to the help of Tsinghua Station: https://mirrors.tuna. tsinghua.edu.cn/help/pypi/

For temporary use, recommended
- The command is pip install -i https://pypi.tuna.tsinghua.edu.cn/simple The name of the package< /span>

Permanent:

Upgrade pip to the latest version (>=10.0.0) and configure it:

pip < span style="color: #0000ff;">install pip -U

pip config set global.index-url https://pypi. tuna.tsinghua.edu.cn/simple

If your network connection to the default source of pip is poor, temporarily use this mirror site to upgrade pip:

ul>

pip install -i https://< /span>pypi.tuna.tsinghua.edu.cn/simple pip -U
