Conda as a package manager helps you find and install packages. If you need a package that requires a different version of Python, you do not need to switch to a different environment manager, because Conda is also an environment manager. With just a few commands, you can set up a completely separate environment to run that different version of Python, while continuing to run your usual version of Python in your normal environment.
Conda treats Python the same as any other package, so it is easy to manage and update multiple installations.
Anaconda supports Python 2.7, 3.4, 3.5, and 3.6. Default Python is 2.7 or 3.6, depending on which installer you used:
* For the installers “Anaconda” and “Miniconda,” the default is 2.7.
* For the installers “Anaconda3” or “Miniconda3,” the default is 3.6.
Anaconda supports Python 3.X. Default Python is 3.8, depending on which installer you used.
## Conda on the IT4Innovations Clusters
On the clusters, we have the Anaconda2 and Anaconda3 software installed. How to use these modules is shown below.
