Frequently asked questions
Getting Anaconda
You can download previous versions of Anaconda from the Anaconda installer archive.
The installation procedures for previous versions are the same as the installation for the current version. For graphical installs, double click the downloaded installer file and follow the prompts. For command line installs, run “bash filename.sh” and follow the prompts. The installer filenames and hashes for previous versions will be different.
Older versions of packages can usually be downloaded from the package repository or from https://anaconda.org/anaconda/PackageName.
Replace PackageName with the name of the desired package.
EXAMPLE: At https://anaconda.org/anaconda/beautifulsoup4, previous versions of beautifulsoup4 are shown on the Files tab.
You can also search for packages from the command line with conda search PackageName.
If your corporate security settings do not allow you to download a Windows .exe executable file, download our zipped file.
Installing Anaconda
After you have the file, it’s the same as any other install. Save a local copy of the appropriate Anaconda installer for the non-networked computer. You can copy the Anaconda installer using many different methods including a portable hard drive, USB drive, or CD.
After copying the installer to the air-gapped machine, follow the installation instructions for your operating system.
Anaconda recommends installing Anaconda or Miniconda into a directory that contains only 7-bit ASCII characters and no spaces, such as C:\anaconda. Do not install into paths that contain spaces such as C:\Program Files or that include Unicode characters outside the 7-bit ASCII character set. This helps ensure correct operation and no errors when using any open-source tools in either Python 3 or Python 2 conda environments.
When installing Anaconda, Anaconda recommends that you do not add Anaconda to the Windows PATH because this can interfere with other software. Instead, open Anaconda with the Start Menu and select Anaconda Prompt, or use Anaconda Navigator (Start Menu - Anaconda Navigator).
Anaconda recommends against adding Anaconda to the PATH manually. During installation, you will be asked “Do you wish the installer to initialize Anaconda3 by running conda init?” Anaconda recommends entering yes to allow the installer to initialize Anaconda3. If you enter no, then conda will not modify your shell scripts at all. In order to initialize after the installation process is done, first run source <path to conda>/bin/activate and then run conda init.
Replace <path-to-anaconda> with the actual path of your installed Anaconda file.
If you accept the default option to install Anaconda on the “default path”, as of version 2024.02-1:
-
For
pkginstallers (such asosx-64andosx-arm64), Anaconda is installed in/opt/anaconda3. -
For
shinstallers, Anaconda is installed in the home directory.
Examples:
-
Windows 10:
C:\Users\<your-username>\Anaconda3\ -
macOS:
/Users/<your-username>/anaconda3for the shell install,/opt/anaconda3for the graphical install. See the macOS install instructions. -
Linux:
/home/<your-username>/anaconda3
If your username includes spaces, as is common on Windows systems, you should not use the default path. See the “In what folder should I install Anaconda on Windows?” FAQ item above.
You do not need to uninstall other Python installations or packages before installing Anaconda. Even if you already have a system Python, another Python installation from a source such as the macOS Homebrew package manager and globally installed packages from pip such as pandas and NumPy, you do not need to uninstall, remove, or change any of them.
Install Anaconda or Miniconda normally. There is no need to set the PYTHONPATH environment variable.
To see if the conda installation of Python is in your PATH variable:
-
On macOS and Linux, open the terminal and run
echo $PATH. -
On Windows, open Anaconda Prompt and run
echo %PATH%.
To see which Python installation is currently set as the default:
-
On macOS and Linux, open the terminal and run
which python. -
On Windows, open Anaconda Prompt and run
where python.
To see which packages are installed in your current conda environment and their version numbers, in your terminal window or Anaconda Prompt, run conda list.
Using conda packages
Make sure the conda package tk is installed:
If it is not installed, run:
Python programs can use TKinter with import Tkinter on Python 2 or import tkinter on Python 3.
Cython needs a C compiler, so you need to install Xcode.
Theano requires gcc for acceleration.
To install Theano with acceleration:
-
On Windows, run
conda install theano. -
On Linux and macOS run
conda install gcc theano.
Theano is available from the default Anaconda channels for Windows, macOS, and Linux with the command conda install theano.
