1. Environmental description
1. win10, no CPU.
2. Cloud server AutoDL
3. Installed software: pyCharm (less used, so not installed)
4. Environment: miniconda
2. miniconda installation
1. Download address
https://docs.conda.io/en/latest/miniconda.html
What is installed is py3.8. Other parameters are selected according to the computer. My computer is win10 64-bit. I downloaded the following software.
edit
Install directly after downloading. After installation, you can find miniconda3 in the menu interface.

2. Conda replacement source
Open the miniconda3 terminal. Windows users cannot directly create a file named .condarc. They can first execute conda config --set show_channel_urls yes to generate the file and then modify it.
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/r - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2 custom_channels: 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 menpo: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud pytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud pytorch-lts: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud simpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
3. pip replacement source
-
Create a new pip folder in C:\Users\your username directory
-
Create pip.ini in the new pip directory (create a new txt and change the suffix to ini)
-
Open with notepad for writing
[global] timeout = 6000 index-url=http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com
3. Pytorch installation
Directly follow the commands given on the official website to download:
Official website address:
Select the corresponding version parameters, and the official website will automatically give the latest installation command.
pip install torch torchvision torchaudio4. Conda usage and operation
1) Check which packages are installed
conda list
2) Check which virtual environments currently exist
conda env list conda info -e
3) Check to update the current conda
conda update conda
3.Python creates a virtual environment
conda create -n your_env_name python=x.x
The anaconda command creates a virtual environment with python version xx and name your_env_name. Your_env_name file can be found under the envs file in the Anaconda installation directory.
4. Activate or switch virtual environments
Open the command line and enter python --version to check the current python version.
Linux: source activate your_env_nam Windows: activate your_env_name
5. Install additional packages on the virtual environment
conda install -n your_env_name [package]
6. Close the virtual environment (i.e. exit from the current environment and return to using the default python version in the PATH environment)
deactivate env_name
Or activate rootswitch back to the root environment
Linux下：source deactivate
7. Delete the virtual environment
conda remove -n your_env_name --all
8. Delete a package in the environment
conda remove --name $your_env_name $package_name
The environment is basically like this. All subsequent projects will create corresponding virtual environments separately. If you are used to Windows, it is recommended to install pycharm. For Linux, just use the terminal!
