MacOS DMG files. Pip-install-src is the argument in the pip install pip-install-src command to install the application on the local Python. Double clicking the dmg will open a new finder window giving you the option to install napari into your Applications folder by dragging the napari icon onto the Applications icon. After you drag the napari icon onto the Applications icon napari will be installed in your Applications folder and available for opening by double clicking on it. Install PIP in Linux Systems. To install pip in Linux, run the appropriate command for your distribution as follows: Install PIP On Debian/Ubuntu # apt install python-pip #python 2 # apt install python3-pip #python 3 Install PIP On CentOS and RHEL. Unluckily, pip is not packaged in official software repositories of CentOS/RHEL. Python is a widely-used programming language used in many of the computer science classes here at St. What is PIL/Pillow? PIL (Python Imaging Library) adds many image processi.

Welcome to the napari installation tutorial!

This tutorial will teach you how to do a clean install of napari. It isaimed at people that just want to use napari. For people also interested incontributing to napari please check our contributingguidelinesfor more advanced installation procedures. At the end of the tutorial you shouldhave napari successfully installed on your computer and be able to make thenapari viewer appear.

installation¶

which distribution to install¶

If you want to contribute back to the napari codebase, you should install fromsource code: see the from source section.

If you only wish to use napari as GUI app (and not from python code), thebundled appis the easiest way to install, it does not require having python pre-installed.

If you are using napari from Python to programmatically interact with the app,you can install via pip, conda-forge, or from source.

from pip, with “batteries included”¶

napari can be installed on most macOS, Linux, and Windows systems with Python3.7, 3.8, and 3.9 using pip:

(See SpecifyingaGUIBackend below for an explanation of the [all]notation.)

Important

While not strictly required, it is highly recommended to installnapari into a clean virtual environment using an environment manager likeconda orvenv. For example, with conda:

from conda-forge¶

If you prefer to manage packages with conda, napari is available on theconda-forge channel. You can install it with:

install from the master branch on Github¶

To install the “next-release” version from github via pip, call

clone the repository locally and install in editable mode¶

To clone the github repository for local install

checking it worked¶

After installation you should be able to launch napari from the command line bysimply running

An empty napari viewer should appear as follows

upgrading¶

If you installed napari with pip you can upgrade by calling

choosing a different Qt backend¶

Specifying a GUI Backend

napari needs a library called Qt to run its user interface(UI). In Python, there are two alternative libraries to run this, calledPyQt5 andPySide2. By default, we don’t choose for you,and simply running pipinstallnapari will not install either. You mightalready have one of them installed in your environment, thanks to otherscientific packages such as Spyder or matplotlib. If neither is available,running napari will result in an error message asking you to install one ofthem.

Running pipinstall'napari[all]' will install the default framework – currentlyPyQt5, but this could change in the future.

To install napari with a specific framework, you can use:

Note: if you switch backends, it’s a good idea to pipuninstall the oneyou’re not using.

installing as a bundled app¶

napari can also be installed as a bundled app on each of the major platforms,MacOS, Windows, and Linux with a simple one click download and installationprocess. You might want to install napari as a bundled app if you are unfamiliarwith installing Python packages or if you were unable to get the installationprocess described above working. The bundled app version of napari is the sameversion that you can get through the above described processes, and can still beextended with napari plugins installed directly via the app.

To access the cross platform bundles you can visit our releasepage and scroll to the release youare interested in and expand the assets tab to get a view that looks likethis:

You can then download the appropriate zip file for your platform.

installing the MacOS bundle¶

Once you have downloaded the MacOS bundle zip you will have a zip file with aname like napari-0.3.7-macOS.zip. After unzipping you will have a file with aname like napari-0.3.7.dmg. Double clicking the dmg will open a new finderwindow giving you the option to install napari into your Applications folderby dragging the napari icon onto the Applications icon.

After you drag the napari icon onto the Applications icon napari will beinstalled in your Applications folder and available for opening by doubleclicking on it.

The first time you try and open napari you will get the “unverified developerwarning” that appears bellow:

Don’t be alarmed, this is because the napari team has not yet obtained adeveloper certificate from Apple, but we will be doing this promptly. It is safeto click “Cancel”. To get napari to open you must enter “Systems Preferences”and click the “Security & Privacy” icon, circled in red below:

Once inside the “Security & Privacy” tab, you should see a message about naparibeing blocked and an “Open Anyway” button, circled in red below:

After clicking this button you’ll get one final warning about napari not beingverified, but now you’ll have an “Open” button, as seen below:

After clicking “Open”, the viewer should appear. Don’t worry, you only have togo through this process once when you install a new bundle.

installing the Windows bundle¶

Once you have downloaded the Windows bundle zip you will have a zip file with aname like napari-0.3.7-Windows.zip. Unzip the bundle (you may like to use atool like 7-zip for this) and double click on msifile, eg: napari-0.3.7.msi

The napari setup wizard will then open. Click “Next” to begin the installation.

After the setup wizard has installed napari, click “Finish” to exit.

Install Pip Git

When you launch the bundled napari app on Windows, first you’ll see an emptycommand terminal appear (do not close this window - you can ignore it). Thecommand terminal will be followed by a napari splash screen, and then the mainnapari user interface window will appear a few seconds later. Note that errorswhich might occur during your napari session will appear on the command terminal

• so if something is not working, it might pay to take a look at the terminal!

You can launch napari from the Windows start menu.

The very first time you launch napari the startup time will be fairly slow, butafter that you will find that napari launches more quickly.

installing the Linux bundle¶
