Install Anaconda on Linux-Centos7
Reload: Install Anaconda (new version 2019) under Linux-Centos7
Anaconda3+Tensorflow/Keras has been installed many times under the linux system, and the installation of Anaconda is really simple, but there are still some jams installed on the new server today, so I decided to tidy up for my future reference.
Environment: Centos 7
Part1. Download Anaconda
Directly in Official Web Download is slow, we recommend using Tsinghua Mirror (you can also change the source of pip to domestic, pip install will be much faster): Tsinghua Open Source Mirror
On the latest date, select an Anaconda3 installation package corresponding to your system version, x86_64 means compatible with 32-bit and 64-bit systems. Right-click the copy link and use wget to download in linux.
wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2019.03-Linux-x86_64.sh
If prompted that there is no wget, install using yum:
yum -y install wget
Part2. Install Anaconda
Execute the file in the download directory with a different name depending on the version you download:
bash Anaconda3-2019.03-Linux-x86_64.sh
Next comes a bunch of icense License statements, all the way back down, with the following text, type yes:
Do you accept the license terms? [yes|no] [no] >>> Please answer 'yes' or 'no': >>> yes
Then choose the installation directory and enter the absolute path if you need to change the Enter without changing it:
(You can view the hard disk mount first, then choose the installation directory by yourself. The statement to view the mount is df-h)
Anaconda3 will now be installed into this location: /root/anaconda3
- Press ENTER to confirm the location
- Press CTRL-C to abort the installation
- Or specify a different location below
[/root/anaconda3] >>>
There may be an error indicating that bunzip2 could not be found:
Anaconda3-2019.03-Linux-x86_64.sh: line 353: bunzip2: command not found
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors
Also install using yum, named bzip2:
yum install -y bzip2
After resolving bzip2, repeat the previous steps to install anaconda3, wait a few moments before you have the option to ask if you need to initialize conda and suggest typing no. If yes is selected, it is at / root/. Automatically adding environment variables to the bashrc directory will cause the base environment to start automatically on startup. (This should be a change to the new version of the installation package. Older versions of the installation package all ask if conda needs to be added to environment variables, and the default direct return Enter is not added, if it is not added later it needs to be added manually.)
Do you wish the installer to initialize Anaconda3
by running conda init? [yes|no]
[no] >>> no
Installation succeeded when prompted as follows:
Thank you for installing Anaconda3!
===========================================================================
Anaconda and JetBrains are working together to bring you Anaconda-powered
environments tightly integrated in the PyCharm IDE.
PyCharm for Anaconda is available at:
https://www.anaconda.com/pycharm
If yes was chosen for conda's initialization, then the environment variable is already configured, enter a simple command to test it:
conda activate # Entering conda environment and appearing (base) indicates successful installation
conda deactivate # Exit conda environment
It is important to note that the new version disables the source activate command, and that if you use an older installation package, you use the following command:
source activate # Entering conda environment and appearing (base) indicates successful installation
source deactivate # Exit conda environment
If conda is initialized with no, you need to configure the environment variable yourself.
Open the profile file:
vi /etc/profile
Add the following statement to the end of the file (the path needs to be changed according to your installation location):
