Anaconda download and installation guide for Python 3.8 version
In today's data science, machine learning and artificial intelligence, Anaconda has been widely popular as a distribution that integrates numerous Python packages. It not only simplifies environmental management, but also greatly improves development efficiency. This article will provide detailed information on how to download and install the Anaconda distribution with Python 3.8 to help readers get started quickly with this powerful tool.
1. Introduction to Anaconda
Anaconda is an open source project developed by Continuum Analytics. It is a collection of data analysis packages for scientific computing, including many popular scientific computing packages such as NumPy, SciPy, pandas, IPython, matplotlib, scikit-learn, etc. At the same time, Anaconda provides a package manager and environment management system called conda, which makes it very convenient for users to install these packages and can easily create different environments to isolate dependencies between different projects.
2. Download Anaconda
- Open a browserAnd visit Anaconda's official website: /products/distribution.
- Find the "Download Anaconda" section on the homepage and click to enter the download page.
- Choose the appropriate version to download:
- For most individual users,Anaconda Individual Editioncan meet the needs;
- Select the corresponding installer according to the operating system (Windows/Mac/Linux);
- In terms of version selection, since our goal is to install Python 3.8, be sure to confirm that the selected installation package supports this version.
- Notice: The latest version provided by Anaconda's official website may have been updated to a higher version of Python. If you download the latest version directly but do not specify Python 3.8 explicitly, newer Python versions may be automatically installed. Therefore, it is best to check the specific information of the installation package before downloading, or manually set the Python version through Anaconda Navigator.
3. Install Anaconda
Windows System
Run after downloading.exeFile, start the installation wizard.
Click "Next" all the way until you see the "Advanced Options" page. Here you can choose whether to add Anaconda to the PATH environment variable according to your needs. It is recommended to check it for easier subsequent operations.
Select Just Me or All Users in the Install for option, the former is only valid for the current account, while the latter is available for all system accounts.
Continue to click "Next" until the installation is completed.
macOS system
- Double-click to download
.pkgFile, start the installation assistant. - Follow the prompts to complete the installation steps, and you can also choose whether to update the system path during the process.
Linux system
Open the terminal, switch to the download directory, and execute the following command:
bash Anaconda3-2021.11-Linux-x86_64.sh
Follow the script prompts to complete the installation process.
For Anaconda to take effect, updates are required.bashrcor.zshrcFile (depending on the shell used), add the following:
export PATH="/home/yourname/anaconda3/bin:$PATH"
Finally, reload the configuration file or restart the terminal.
4. Verify the installation results
No matter which operating system is installed, you can enter it through the terminal (or command line)conda --versionandpython --versionTo verify that Anaconda and the Python version it carries successfully are installed.
5. Set Python 3.8 as the default version
Assuming that Anaconda has been installed correctly as described above, but the default Python version installed is not the 3.8 we want, you can adjust it by following the following steps:
- use
conda env listView all created environments. - If there is no Python 3.8 environment, you can create a new environment:
conda create -n py38 python=3.8
Activate the environment you just created:
conda activate py38
Check the version of Python in the currently activated environment:
python --version
The output result should bePython 3.。
In order to make it easier to switch the environment in the future, you can consider using the alias function. For example,.bashrcor.zshrcAdd a line of commands:
alias py38="conda activate py38"
This way, whenever we want to use Python 3.8, just enterpy38You can quickly switch to the corresponding environment.
Six, the last
Through the introduction of this article, I believe that readers have mastered the method of downloading and installing Anaconda with Python 3.8. In addition, we also explored how to adjust the Python version in Anaconda according to actual needs. After mastering these skills, both beginners and data scientists with some experience can carry out their work more efficiently. With the development of technology in the future, Anaconda will inevitably bring more convenient functions, let's wait and see!
