The following works on Windows, with an Anaconda python 3.5 build (and installs all the dependencies):

pip install git+https://github.com/cvhciKIT/sloth.git
conda install -c anaconda pyqt=4.11.4
conda install scikit-image

Sloth is an executable Python script . So, to run it you can call it from terminal:

PATH_PREFIX_TO_YOUR_PYTHON/Python27/Lib/site-packages/sloth/bin/sloth

You might add sloth script directory to your PATH , by editing yout .bashrc file:

export PATH=$PATH:PUT_PATH_TO_SLOTH_HERE

And then run source .bashrc in order for changes to take effect. After that, typing sloth in a terminal window should open the GUI.

In Windows, I managed to run it using Git Bash (Git installation for Windows provides a Bash emulator by default) . In a Git Bash terminal Window, use the following (you may need to chage if your Python installation directory is different):

/c/Python27/Lib/site-packages/sloth/bin/sloth

  • this sounds standard, but keep getting sloth command not found, even after exporting the path as you've described and sourcing it (which i do for most other packages with success). so maybe ive got a non standard install path that sloth doesnt expect or something.. – jsky Jul 13 '17 at 02:43

complete installation "sloth" under Windows:

  1. conda create -n slo_py35 python=3.5

  2. activate slo_py35 git config --global http.proxy http://proxy.xxx.de:port #only if proxy available pip install git+https://github.com/cvhciKIT/sloth.git

  3. conda install -c anaconda pyqt=4.11.4 conda install scikit-image #or if it does not work, take: pip install scikit-image

  4. conda env list #shows the path to the installation for example: D:\...\anaconda3\envs\slo_py35\

  5. run sloth: D:\...\anaconda3\envs\slo_py35\sloth\bin> python sloth

  6. run sloth with the included example: D:\...\anaconda3\envs\slo_py35\sloth\bin> python sloth D:\xxx\examples\example1_labels.json

possible problems: FileNotFoundError: No such file or directory: 'D:\...\anaconda3\envs\slo_py35\lib\site-packages\sloth\gui\labeltool.ui'

solutions: the ui-file exists and is just in the wrong place D:\...\anaconda3\envs\slo_py35\sloth\gui\labeltool.ui The ui-file only needs to be copied to the correct path, see error message, then it runs.
