Chainer Chemistry is a deep learning framework (based on Chainer) with applications in Biology and Chemistry. It supports various state-of-the-art models (especially GCNN - Graph Convolutional Neural Network) for chemical property prediction.
For more information, please refer to the documentation. Also, a quick introduction to deep learning for molecules and Chainer Chemistry is available here.
Chainer Chemistry depends on the following packages:
These are automatically added to the system when installing the library via the
pip command (see Installation). However, the following needs to be
installed manually:
Please refer to the RDKit documentation for more information regarding the installation steps.
Note that only the following versions of Chainer Chemistry's dependencies are currently supported:
| Chainer Chemistry | Chainer | RDKit | Python |
|---|---|---|---|
| v0.1.0 ~ v0.3.0 | v2.0 ~ v3.0 | 2017.09.3.0 | 2.7, 3.5, 3.6 |
| v0.4.0 | v3.0 ~ v4.0 *1 | 2017.09.3.0 | 2.7, 3.5, 3.6 |
| v0.5.0 | v3.0 ~ v5.0 *2 | 2017.09.3.0 | 2.7, 3.5, 3.6 |
| v0.6.0 | v6.0 ~ *3 | 2017.09.3.0 | 2.7, 3.5, 3.6 |
| v0.7.0 ~ v0.7.1 | v7.0 ~ | 2019.03.2.0 | 3.6, 3.7 *4 |
| master branch *5 | v7.0 ~ | 2019.03.2.0 | 3.6, 3.7 |
[Footnote]
*1: We used FunctionNode in this PR,
which is introduced after chainer v3. See this issue for details.
*2: Saliency modules only work after chainer v5.
*3: Chainer v6 is released and ChainerX is newly introduced. In order to support this new feature & API, we broke backward compatibility for chainer chemistry v0.6.0 release. See ChainerX Documentation for details.
*4: python 2.x support is dropped, following the same policy with chainer and rdkit.
*5: As announced in chainer blog, further development will be limited to only serious bug-fixes and maintenance.
