1. Problem Description: CONDA is unable to create a virtual environment and install other third-party packages. The error is as follows:

2. Error reason: the access speed of the default image source is too slow, which will lead to timeout, resulting in update and download failure.

3. Solution: change the image source to Tsinghua image source, and delete the default image source.

3.1. First, execute the following commands to replace the image source

conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/

conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/

conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

conda config –set show_ channel_ urls yes

3.2. Change the image source profile

Find the. Condarc file in the user’s root directory (C:// users \ \ user name), open and edit it, and delete the default configuration line.

4. Re create the virtual environment, success!
