Installation of PYME on 64 bit Windows, OSX, or Linux

PYME requires python (version 2.7) and a number of additional scientific packages. Although it is possible to install all packages individually, and then install PYME, by far the easiest way to get a system up and running is to install a pre-packaged ‘scientfic python’ distribution. Anaconda is one such distribution which is free for both academic and commercial use and includes extensive package management capabilities which allow us to easily distribute and update PYME on a variety of platforms. We currently provide compiled packages for 64 bit windows, OSX, and Linux.


This is the recommended way of installing PYME in most circumstances. If you absolutely don’t want to deal with the command line there is also a completely graphical way of doing the installation. If you are looking to actively develop PYME or want to use it to control microscope hardware, see Installation for development or instrument control.

STEP 1: Installing Anaconda

Download and install Anaconda from Choose the 64 bit version of Python 2.7 for your prefered platform.


Anaconda is available in both Python 2.7 and Python 3.x flavours. PYME will only work with the Python 2.7 version.

STEP 2: Installing PYME using conda

Anaconda comes with a built in package manager called conda which can be used to install additional packages. In addition to the main set of packages maintained by Continuim Analytics (the developers of anaconda) conda can install packages which members of the community have uploaded to The python-microscopy package and a number of it’s dependencies are available through the david_baddeley binstar channel. To install PYME, we first need to tell conda to use the david_baddeley channel in addition to it’s existing channels. We can simply tell conda to install the package named python-microscopy.

This is accomplished by opening a terminal window (On OSX use spotlight to launch the Terminal app, on Windows, launch the Anaconda Command Prompt from the “Anaconda” group in the start menu) and running the following two commands:

conda config --add channels david_baddeley
conda install python-microscopy

This should download and install PYME, along with a number of it’s dependencies.


Troubleshooting: There appears to be a dependency conflict between the mayavi (which we use for 3D visualization) and navigator-updater packages in recent versions of Anaconda. As navigator-updater is installed by default, this can prevent python-microscopy from installing. If the installation above fails with an error message about dependencies, try running conda uninstall navigator-updater and then re-running conda install python-microscopy.

STEP 3: Verifying the Installation

From the command prompt, launch any of the following programs, which should have been installed as part of PYME.

dh5view -t -m lite
This is the data viewer for image files (also used to launch localization analysis). The -t -m lite options
initiates a test mode which should display a image consisting of random noise.
PYMEAcquire This is the data acquistion component, which when launched without any options will start with simulated hardware.
VisGUI This is a viewer for point data sets. When launched without any parameters it will show a large pink triangle.

STEP 4: Setting up bioformats importing [optional]

PYME (or specifically dh5view) can use bioformats to load data formats it doesn’t natively support. For this to work you need to have java (JRE should be enough, but as the JDK is needed to compile the interface modules I have only tested with that) and the following 2 python modules installed:

  • python-javabridge
  • python-bioformats

For OSX, I have compiled versions of these in the david_baddeley channel which you can get using conda install. On other platforms you will have to download the JDK and build these from source (both are on github). You might also get away with pip install ing them.
