Optimize conda configuration and run Python programs efficiently
When developing Python, we often use conda to manage the Python environment. conda is an open source package manager and environment manager that can help us install, manage and upgrade the required Python packages more easily. However, if we do not optimize conda configuration, it may cause the Python program to run inefficiently, affecting development efficiency and user experience. This article will introduce how to optimize conda configuration to achieve the purpose of running Python programs efficiently.
- Use Tsinghua University mirror source
conda’s default official mirror source is often slower, especially when accessed domestically. In order to speed up the download speed, we can configure the Tsinghua University mirror source. Open the terminal and enter the following command:
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ conda config --set show_channel_urls yes
In this way, conda will use the Tsinghua University mirror source to download and update the package, improving the download speed.
- Use domestic mirror source to update conda
conda itself also needs to be upgraded from time to time to maintain stability and functional improvements. For domestic users, using domestic mirror sources to update conda can obtain the latest version faster. Enter the following command in the terminal:
conda update conda
- Create an independent Python environment
Creating an independent Python environment for each project can help us isolate libraries between different projects version to avoid version conflicts. Enter the following command in the terminal:
conda create -n myenv python=3.7
where, myenv is the environment name, and python=3.7 specifies the Python version. After creating the environment, use the following command to activate the environment:
conda activate myenv
In this way, we can install the required packages in this environment without affecting other environments.
- Use pip to install the required packages
Although conda can install, manage and upgrade Python packages, in some cases, it may be more convenient to use pip. In the activated conda environment, install pip through the following command:
conda install pip
Then you can use pip to install the required packages. The command is similar to:
pip install package_name
- Configure the conda virtual environment cache
Conda will cache the downloaded packages in the "~/.conda/pkgs" directory by default, which will occupy a lot of hard disk space. We can modify the cache directory by configuring the environment variable CONDA_PKGS_DIRS. Enter the following command in the terminal:
nano ~/.bashrc
Add the following content in the .bashrc file, save and exit:
export CONDA_PKGS_DIRS="/path/to/new/cache/folder"
Modify "/path/to/new/cache/folder" as you expect The cache directory path.
- Install and use mamba
mamba is a fast alternative to conda package manager, which can provide faster package management speed. You can use the following command to install mamba:
conda install mamba -n base -c conda-forge
After the installation is complete, you can use mamba to replace conda to execute some commands, such as installing packages, updating the environment, etc. The functions of mamba are basically the same as conda, but it is faster and more efficient.
Through the above optimization measures, we can improve the efficiency of conda and enable Python programs to run more efficiently. At the same time, configuring an independent Python environment can avoid version conflicts and ensure the stability of the project. I hope this article will be helpful to your Python development work!

When loading CentOS-7.0-1406, there are many optional versions. For ordinary users, they don’t know which one to choose. Here is a brief introduction: (1) CentOS-xxxx-LiveCD.ios and CentOS-xxxx- What is the difference between bin-DVD.iso? The former only has 700M, and the latter has 3.8G. The difference is not only in size, but the more essential difference is that CentOS-xxxx-LiveCD.ios can only be loaded into the memory and run, and cannot be installed. Only CentOS-xxx-bin-DVD1.iso can be installed on the hard disk. (2) CentOS-xxx-bin-DVD1.iso, Ce

Building a mirror site requires three steps: find a faster domestic source, install and configure tomcat, and synchronize target source data. Domestic sources are also synchronized with foreign official servers. We need to find domestic sources that support rsync.

The Python program development process includes the following steps: Requirements analysis: clarify business needs and project goals. Design: Determine architecture and data structures, draw flowcharts or use design patterns. Writing code: Program in Python, following coding conventions and documentation comments. Testing: Writing unit and integration tests, conducting manual testing. Review and Refactor: Review code to find flaws and improve readability. Deploy: Deploy the code to the target environment. Maintenance: Fix bugs, improve functionality, and monitor updates.
