Instructions for installing and uninstalling distoptica

Installing distoptica

For all installation scenarios, first open up the appropriate command line interface. On Unix-based systems, you could open e.g. a terminal. On Windows systems you could open e.g. an Anaconda Prompt as an administrator.

Before installing distoptica, it is recommended that users install PyTorch in the same environment that they intend to install distoptica according to the instructions given here for their preferred PyTorch installation option.

Installing distoptica using pip

Before installing distoptica, make sure that you have activated the (virtual) environment in which you intend to install said package. After which, simply run the following command:

pip install distoptica

The above command will install the latest stable version of distoptica.

To install the latest development version from the main branch of the distoptica GitHub repository, one must first clone the repository by running the following command:

git clone https://github.com/mrfitzpa/distoptica.git

Next, change into the root of the cloned repository, and then run the following command:

pip install .

Note that you must include the period as well. The above command executes a standard installation of distoptica.

Optionally, for additional features in distoptica, one can install additional dependencies upon installing distoptica. To install a subset of additional dependencies (along with the standard installation), run the following command from the root of the repository:

pip install .[<selector>]

where <selector> can be one of the following:

• tests: to install the dependencies necessary for running unit tests;
• examples: to install the dependencies necessary for executing files stored in <root>/examples, where <root> is the root of the repository;
• docs: to install the dependencies necessary for documentation generation;
• all: to install all of the above optional dependencies.

Alternatively, one can run:

pip install distoptica[<selector>]

elsewhere in order to install the latest stable version of distoptica, along with the subset of additional dependencies specified by <selector>.

Installing distoptica using conda

Before proceeding, make sure that you have activated the (virtual) conda environment in which you intend to install said package. For Windows systems, users must install PyTorch separately prior to following the remaining instructions below.

To install distoptica using the conda package manager, run the following command:

conda install -c conda-forge distoptica

The above command will install the latest stable version of distoptica.

Uninstalling distoptica

If distoptica was installed using pip, then to uninstall, run the following command:

pip uninstall distoptica

If distoptica was installed using conda, then to uninstall, run the following command:

conda remove distoptica

Learning how to use distoptica

For those new to the distoptica library, it is recommended that they take a look at the Examples page, which contain code examples that show how one can use the distoptica library. While going through the examples, readers can consult the distoptica reference guide to understand what each line of code is doing.
