Thanks to work by Sebastian Luna-Valero (@sebastian-luna-valero) and others, pyvips is now in conda!

It includes a libvips binary with most optional packages enabled, including things like openslide and matio. It is currently missing HEIC and libjpeg-turbo, but perhaps they will come.

Windows support is blocked on gdk-pixbuf, unfortunately. The pyvips README has some notes on Windows install.


To install, first install Anaconda.

Next, create a python environment to install pyvips in. You can use any Python version, but 3.7 is the current latest:

conda create --name vips python=3.7

And activate it:

conda activate vips

pyvips is in conda-forge, the community conda channel, so install with:

conda install --channel conda-forge pyvips


You should now be able to use pyvips. For example:

(vips) john@katamata:~$ python
Python 3.7.4 (default, Aug 13 2019, 15:17:50) 
[Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyvips
>>> x = pyvips.Image.new_from_file("/Users/john/pics/openslide/normal_091.tif")
>>> x.width
>>> x.height


Step out of the vips environment when you are done testing:

conda deactivate

And you can now remove the vips environment.

conda remove --name vips --all
