Fast and scalable fitting of over-determined generalized-linear models (GLMs)
Project description
Fast and scalable fitting of over-determined generalized-linear models (GLMs)
batchglm was developed in the context of diffxpy to allow fast model fitting for differential expression analysis for single-cell RNA-seq data. However, one can use batchglm or its concepts in other scenarios where over-determined GLMs are encountered. batchglm is based on TensorFlow
Installation
- Install tensorflow, see below. Please use the pip installation if you are unsure.
- Clone the GitHub repository of batchglm.
- cd into the clone.
- pip install -e .
Tensorflow installation
Tensorflow can be installed like any other package or can be compiled from source to allow for optimization of the software to the given hardware. Compiling tensorflow from source can significantly improve the performance, since this allows tensorflow to make use of all available CPU-specific instructions. Hardware optimization takes longer but is only required once during installation and is recommended if batchglm is used often or on large data sets. We summarize a few key steps here, an extensive up-to-date installation guide can be found here: https://www.tensorflow.org/install/
Out-of-the-box tensorflow installation
You can install tensorflow via pip or via conda.
pip
- CPU-only:
pip install tf-nightly
- GPU:
pip install tf-nightly-gpu
Hardware-optimized tensorflow installation (compiling from source)
Please refer to https://www.tensorflow.org/install/ .
Pre-requirements
First, you have to install bazel (a build tool).
- On MacBook:
brew install bazel
- On linux:
- Use Anaconda/Miniconda:
conda install bazel
- Official / Distribution-specific ways: https://docs.bazel.build/versions/master/install.html
- Use Anaconda/Miniconda:
Compilation
This does not work yet.
- Get newest TensorFlow repo from github via git clone:
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow/
git checkout <release>
./configure
bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
pip install /tmp/tensorflow_pkg/tensorflow-<blah>.whl
Building the documentation
The documentation is maintained in the docs/
directory.
The built documentation will be saved in build/docs
.
- Make sure
sphinx
,sphinx-autodoc-typehints
andsphinx_rtd_theme
packages are installed (install via pip for example). cd docs/
make html
