Installation
cblearn
requires Python 3.9 or newer.
We recommend using Anaconda to install Python and
dependencies in separated environments.
The package is mainly tested on Linux, but Windows and Mac OS should work, too.
conda create -n cblearn python==3.9
conda activate cblearn
User Installation
cblearn
and can be installed using pip:
pip install cblearn
This will install the minimal set of required packages, sufficient for most uses and saving disk space.
However, some features require more packages that can be installed by adding an option
to the install command.
Extra Requirements
Extra requirements can be installed by adding an option
to the install command and enable more advanced features.
Some of those extra dependencies need non-Python packages to be installed first.
$ pip install cblearn[torch,wrapper] h5py
- torch
Most estimators provide an (optional) implementation using
pytorch
to run large datasets on CPU and GPU. This requires thepytorch
package to be installed manually or by adding thetorch`
option to the install command. Note thatpytorch
might need about 1GB of disk space.- wrapper
The estimators in Wrapper provide an Python interface to the original implementation in
R
-lang. This requires therpy2
package to be installed by adding thewrapper
option to the install command. Additionally, this requires an installedR
interpreter whit must available be in thePATH
environment variable. TheR
packages are installed automatically upon the first use of the estimators.- h5py
The function
cblearn.datasets.fetch_imagenet_similarity()
requires theh5py
package to load the dataset. This can package can be installed with pip. Note that some platforms require additionally thehdf5
libraries to be installed
Contributor Installation
If you want to make changes to the code or documentation, you should first download the repository and install the project in developer mode with developer dependencies. This way, changes in the code are directly considered without the need for re-installation. Additionally, packages required to run the tests and build the documentation are installed.
$ git clone git@github.com:cblearn/cblearn.git
$ cd cblearn
$ pip install -e.[tests,docs,torch,wrapper]
The -e
option installs the package in developer mode such that changes in the code are considered directly without re-installation.
- tests
To run the unit tests, the
pytest
package is required, which can be installed by adding thetests
option to the install command.- docs
Building these docs requires the
sphinx
package, which can be installed by adding the docs option to the install command.
Now you can run the tests and build the documentation:
$ python -m pytest --remote-data # should run all tests; this can take a while.
$ cd docs
$ make html # should generate docs/_build/html/index.html
