## CCSD
### Introduction
Complex object generation is a challenging problem with application in various fields such as drug discovery. The CCSD model offers a novel approach to tackle this problem by leveraging Diffusion Models and Stochastic Differential Equations to generate Combinatorial Complexes (CC). This topological structure generalizes the different mathematical stuctures used in Topological/Geometric Deep Learning to represent complex objects with higher-order structures and relations. The integration of the higher-order domain during the generation enhances the learning of the underlying distribution of the data and thus, allows for better data generation.
If you find this project interesting, we would appreciate your support by leaving a star ⭐ on this [GitHub repository](https://github.com/AdrienC21/CCSD).
Code still in **Alpha version!**
### Why CCSD?
CCSD stands out from traditional complex object generation models due to the following key advantages:
- *Combinatorial Complexes:* The model generates Combinatorial Complexes, enabling the synthesis of complex objects with rich structures and relationships.
- *Score-Based Diffusion:* CCSD utilizes score-based diffusion techniques, allowing for efficient, high-quality and state-of-the-art complex object generation.
- *Enhanced "Realism":* By incorporating higher-order structures, the generated objects are more representative of the underlying data distribution.
Also, this **repository is highly documented and commented**, which makes it easy to use, understand, deploy, and which offers endless possibilities for improvements.
### Author
The research has been conducted by **Adrien Carrel** as part of his requirements for the MSc degree in Advanced Computing of Imperial College London, United Kingdom, and his requirements for the MEng in Applied Mathematics (Diplôme d'Ingénieur) at CentraleSupélec, France.

### Contributions
We welcome new contributors with various background and programming levels who would like to contribute to the fields of diffusion models and topological deep learning. Feel free to suggest new ideas, submit pull requests, etc.
Feel free to check our [Code of Conduct](https://github.com/AdrienC21/CCSD/CODE_OF_CONDUCT.md) if you wish to contribute.
## Installation
If you encounter an error during the installation, please refer to the section **Commons errors** below. If you are creating an Ubuntu instance on a Public Cloud service to train/sample from the model, you may want to use the `post_installation_script.sh` script provided to automate the process (just modify the **Git configurations** section inside the script with your details).
### Using pip
To get started with CCSD, you can install the package using pip by typing the command:
```bash
pip install ccsd
```
### Manually
If you encounter, if you want to use the latest version, or if you prefer the command line interface, you can use it locally by cloning or forking this repository to your local machine.
```bash
git clone https://github.com/AdrienC21/CCSD.git
```
### Next steps
#### Plotly engine
For Windows users, the recommended version of kaleido is *0.1.0.post1*. You can install it by typing:
```bash
pip install kaleido==0.1.0post1
```
For Linux users, the latest version of kaleido seems fine. For those who want to use `orca`, you can install it via the *npm* command of *Node.js*. For the installation, type:
```bash
sudo NEEDRESTART_MODE=a apt install -y nodejs
sudo NEEDRESTART_MODE=a apt install -y npm
npm install -g electron@6.1.4 orca
```
#### Dependencies and other packages/libraries
Install the dependencies (see the section **Dependencies** below).
When installing PyTorch and its componenents, or when install TopoModelX along with TopoNetX, run the commands below:
```bash
pip install torch==2.0.1 --extra-index-url https://download.pytorch.org/whl/${CUDA}
pip install torch-scatter torch-sparse -f https://data.pyg.org/whl/torch-2.0.1+${CUDA}.html
```
where ${CUDA} could be `cu117`, `cu118`, or `cpu` if you want to use the CPU. For GPU, we recommend `cu118`. Also, TopoModelX should be installed after TopoNetX to avoid versioning issues.
If you are using a **Linux** system, you may need to install libxrender1 by typing:
```bash
sudo apt-get install libxrender1
```

## Usage
For a more complete documentation on all the classes and functions, please refer to the **Documentation** page (link in the section below) and [here](https://readthedocs.org/projects/ccsd/).
### General
To use CCSD, follow the steps outlined below:
**Edit your general configurations:**
Edit the file `config\general_config.py` to provide your *wandb* (Weights & Biases) information (if you want to use wandb), your timezone, and some other general parameters.
Edit the `engine` value with the plotly engine you want to use. For Windows users, we recommend `kaleido` (see installation instructions below). For Linux users, we recommend `orca` (see installation instructions below).
**Execute the code:**
You can either use the command line or directly the CCSD class (more information in the subsections below).
**Combinatorial Complexes:**
To generate combinatorial complexes and not graphs, just put the parameter `is_cc` to True in your configuration files, specify the `d_min` and `d_max` parameters of your dataset (see the thesis for more information on that), and pick a ScoreNetwork model for the rank2 score predictions (see example of configurations).
**Figures and output:**
The figures, the graphs, combinatorial complexes, molecules, etc, will all be saved into a `samples` folder, and in the logs folders `logs_sample` and `logs_train`.
The output in the command line should look like below, where a logo is printed, the current experiment information, and then the training/sampling information:

## Commons errors
### Installation of MOSES
If you encounter an error during the installation of MOSES, please follow the steps below:
First, if you are on Windows, make sure you have installed the *C++ Dev kit via Visual Studio 2022 community*.
Then, for all users, install rdkit, Cython, and pomegranate using the commands:
```bash
pip install rdkit
pip install Cython
pip install pomegranate
```
Finally, either install MOSES directly using:
```bash
pip install molsets
```
**Or**, first install lfs by running
```bash
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
sudo apt-get install git-lfs
git-lfs install
```
And then use one of the two options below to install MOSES:
1 - via git
```bash
git lfs install
pip install git+https://github.com/molecularsets/moses.git
```
2 - install it manually (if the previous steps doesn't work):
```bash
git lfs install
git clone https://github.com/molecularsets/moses.git
cd moses
python setup.py install
```
### Package-related errors
The errors related to packages (MOSES, TopoNetX, etc) can be fixed by running the script `apply_fixes.py` located in `.github/workflows/` or by following the steps for each individual packages below:
#### Error due to MOSES
If you get an error related to a `._append` method that no longer exists in Pandas and that is still used in the MOSES package, please replace in the MOSES package the file `utils.py` with the one provided in this repository: **fixes\utils.py**. The MOSES `utils.py` file should be located somewhere like:
`C:\Users\<username>\miniconda3\lib\site-packages\moses\metrics\utils.py` or `miniconda\lib\python3.11\site-packages\molsets-1.0-py3.11.egg\moses\metrics\utils.py`
More precisely the error should look like this:
```bash
_mcf.append(_pains, sort=True)['smarts'].values]
...
AttributeError: 'DataFrame' object has no attribute 'append'
```
The trick is to replace this line (24) by:
```python
pd.concat([_mcf, _pains], sort=True)['smarts'].values]
```
**Remark:** The entire operation can be done through the command line by using sed:
```bash
sed -i "24s/.*/\t\t\tpd.concat([_mcf, _pains], sort=True)[\o047smarts\o047].values]/" <path_to_moses_utils.py>
```
#### Error due to TopoNetX when running the tests
Install an old version of `TopoNetX`, by running for example the command:
```bash
pip install git+https://github.com/pyt-team/TopoNetX.git@a389bd8bb11c731bb98d79da8392e3396ea9db8c
```
Then, replace the file `combinatorial_complex.py` of TopoNetX by the updated one provided in this repository: **fixes\combinatorial_complex.py**
The file in TopoNetX should be located somewhere like:
`C:\Users\<username>\miniconda3\Lib\site-packages\toponetx\classes\combinatorial_complex.py` or `miniconda\lib\python3.11\site-packages\toponetx\classes\combinatorial_complex.py`

The CCSD model offers a novel approach to tackle this problem by leveraging Diffusion Models and Stochastic Differential Equations to generate Combinatorial Complexes (CC). This topological structure generalizes the different mathematical stuctures used in Topological/Geometric Deep Learning to represent complex objects with higher-order structures and relations. The integration of the higher-order domain during the generation enhances the learning of the underlying distribution of the data and thus, allows for better data generation.\r\n\r\nIf you find this project interesting, we would appreciate your support by leaving a star \u2b50 on this [GitHub repository](https://github.com/AdrienC21/CCSD).\r\n\r\nCode still in **Alpha version!**\r\n\r\n### Why CCSD?\r\n\r\nCCSD stands out from traditional complex object generation models due to the following key advantages:\r\n\r\n- *Combinatorial Complexes:* The model generates Combinatorial Complexes, enabling the synthesis of complex objects with rich structures and relationships.\r\n\r\n- *Score-Based Diffusion:* CCSD utilizes score-based diffusion techniques, allowing for efficient, high-quality and state-of-the-art complex object generation.\r\n\r\n- *Enhanced \"Realism\":* By incorporating higher-order structures, the generated objects are more representative of the underlying data distribution.\r\n\r\nAlso, this **repository is highly documented and commented**, which makes it easy to use, understand, deploy, and which offers endless possibilities for improvements.\r\n\r\n### Author\r\n\r\nThe research has been conducted by **Adrien Carrel** as part of his requirements for the MSc degree in Advanced Computing of Imperial College London, United Kingdom, and his requirements for the MEng in Applied Mathematics (Dipl\u00f4me d'Ing\u00e9nieur) at CentraleSup\u00e9lec, France.\r\n\r\n<a href=\"https://linkedin.com/in/adrien.carrel/\" target=\"_blank\"><img align=\"center\" src=\"https://cdn.jsdelivr.net/npm/simple-icons@3.0.1/icons/linkedin.svg\" alt=\"linkedin\" height=\"39\" width=\"52\"/></a>\r\n<a href=\"https://www.instagram.com/adrien.carrel\" target=\"_blank\"><img align=\"center\" src=\"https://cdn.jsdelivr.net/npm/simple-icons@3.0.1/icons/instagram.svg\" alt=\"instagram\" height=\"39\" width=\"52\" /></a>\r\n<a href=\"https://github.com/AdrienC21/\" target=\"_blank\"><img align=\"center\" src=\"https://cdn.jsdelivr.net/npm/simple-icons@3.0.1/icons/github.svg\" alt=\"github\" height=\"39\" width=\"52\" /></a>\r\n\r\nThis project has been **supervised by [Dr. Tolga Birdal](https://www.imperial.ac.uk/people/t.birdal)**, Assistant Professor (Lecturer) in the Department of Computing of Imperial College London.\r\n\r\n### Contributions\r\n\r\nWe welcome new contributors with various background and programming levels who would like to contribute to the fields of diffusion models and topological deep learning. Feel free to suggest new ideas, submit pull requests, etc.\r\n\r\nFeel free to check our [Code of Conduct](https://github.com/AdrienC21/CCSD/CODE_OF_CONDUCT.md) if you wish to contribute.\r\n\r\n## Installation\r\n\r\nIf you encounter an error during the installation, please refer to the section **Commons errors** below. If you are creating an Ubuntu instance on a Public Cloud service to train/sample from the model, you may want to use the `post_installation_script.sh` script provided to automate the process (just modify the **Git configurations** section inside the script with your details).\r\n\r\n### Using pip\r\n\r\nTo get started with CCSD, you can install the package using pip by typing the command:\r\n\r\n```bash\r\npip install ccsd\r\n```\r\n\r\n### Manually\r\n\r\nIf you encounter, if you want to use the latest version, or if you prefer the command line interface, you can use it locally by cloning or forking this repository to your local machine.\r\n\r\n```bash\r\ngit clone https://github.com/AdrienC21/CCSD.git\r\n```\r\n\r\n### Next steps\r\n\r\n#### Plotly engine\r\n\r\nFor Windows users, the recommended version of kaleido is *0.1.0.post1*. You can install it by typing:\r\n\r\n```bash\r\npip install kaleido==0.1.0post1\r\n```\r\n\r\nFor Linux users, the latest version of kaleido seems fine. For those who want to use `orca`, you can install it via the *npm* command of *Node.js*. For the installation, type:\r\n\r\n```bash\r\nsudo NEEDRESTART_MODE=a apt install -y nodejs\r\nsudo NEEDRESTART_MODE=a apt install -y npm\r\nnpm install -g electron@6.1.4 orca\r\n```\r\n\r\n#### Dependencies and other packages/libraries\r\n\r\nInstall the dependencies (see the section **Dependencies** below).\r\n\r\nWhen installing PyTorch and its componenents, or when install TopoModelX along with TopoNetX, run the commands below:\r\n\r\n```bash\r\npip install torch==2.0.1 --extra-index-url https://download.pytorch.org/whl/${CUDA}\r\npip install torch-scatter torch-sparse -f https://data.pyg.org/whl/torch-2.0.1+${CUDA}.html\r\n```\r\n\r\nwhere ${CUDA} could be `cu117`, `cu118`, or `cpu` if you want to use the CPU. For GPU, we recommend `cu118`. Also, TopoModelX should be installed after TopoNetX to avoid versioning issues.\r\n\r\nIf you are using a **Linux** system, you may need to install libxrender1 by typing:\r\n\r\n```bash\r\nsudo apt-get install libxrender1\r\n```\r\n\r\n#### Tests and errors\r\n\r\nTo test your installation, refer to the section **Testing** below.\r\n\r\nIf you encounter an error, please refer to the section **Commons errors** below.\r\n\r\n## Dependencies\r\n\r\nCCSD requires a recent version of Python, probably 3.7, but preferably **3.10 or higher**.\r\n\r\nIt also requires the following dependencies:\r\n\r\n- dill>=0.3.6\r\n- easydict>=1.10\r\n- freezegun>=1.2.2\r\n- hypernetx>=1.2.5\r\n- imageio>=2.31.1\r\n- joblib>=1.3.1\r\n- kaleido>=0.1.0.post1\r\n- matplotlib>=3.7.2\r\n- networkx>=2.8.8\r\n- numpy>=1.24.4\r\n- pandas>=2.0.3\r\n- plotly>=5.15.0\r\n- pyemd>=1.0.0\r\n- pytest>=7.4.0\r\n- pytz>=2023.3\r\n- pyyaml>=6.0\r\n- rdkit>=2023.3.2\r\n- scikit_learn>=1.3.0\r\n- scipy>=1.11.1\r\n- Cython\r\n- pomegranate\r\n- toponetx\r\n- torch>=2.0.1\r\n- tqdm>=4.65.0\r\n- molsets>=0.3.1\r\n- pytest-cov\r\n- wandb\r\n- pandas>=2.0.3\r\n\r\nPlease make sure you have the required dependencies installed before using CCSD.\r\n\r\nYou can install all of them by running the command:\r\n\r\n```bash\r\npip install -r requirements.txt\r\n```\r\n\r\n## Testing\r\n\r\nTo ensure the correctness and robustness of CCSD and to allow researchers to build upon this tool, we have provided an extensive test suite. To run the tests, clone the repository, change your directory to the root folder of this project and execute the following command:\r\n\r\n```bash\r\npytest tests/ -W ignore::DeprecationWarning\r\n```\r\n\r\nIf you encounter an error during the testing, please refer to the section **Commons errors** below.\r\n\r\nThe output should look like this:\r\n\r\n```bash\r\n==================================================== test session starts ====================================================\r\n\r\n...\r\n\r\ntests\\utils\\test_mol_utils.py ..................

It contains more information regarding all the classes and functions of this package.\r\n\r\n## Commons errors\r\n\r\n### Installation of MOSES\r\n\r\nIf you encounter an error during the installation of MOSES, please follow the steps below:\r\n\r\nFirst, if you are on Windows, make sure you have installed the *C++ Dev kit via Visual Studio 2022 community*.\r\n\r\nThen, for all users, install rdkit, Cython, and pomegranate using the commands:\r\n\r\n```bash\r\npip install rdkit\r\npip install Cython\r\npip install pomegranate\r\n```\r\n\r\nFinally, either install MOSES directly using:\r\n\r\n```bash\r\npip install molsets\r\n```\r\n\r\n**Or**, first install lfs by running\r\n\r\n```bash\r\ncurl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash\r\nsudo apt-get install git-lfs\r\ngit-lfs install\r\n```\r\n\r\nAnd then use one of the two options below to install MOSES:\r\n\r\n1 - via git\r\n\r\n```bash\r\ngit lfs install\r\npip install git+https://github.com/molecularsets/moses.git\r\n```\r\n\r\n2 - install it manually (if the previous steps doesn't work):\r\n\r\n```bash\r\ngit lfs install\r\ngit clone https://github.com/molecularsets/moses.git\r\ncd moses\r\npython setup.py install\r\n```\r\n\r\n### Package-related errors\r\n\r\nThe errors related to packages (MOSES, TopoNetX, etc) can be fixed by running the script `apply_fixes.py` located in `.github/workflows/` or by following the steps for each individual packages below:\r\n\r\n#### Error due to MOSES\r\n\r\nIf you get an error related to a `._append` method that no longer exists in Pandas and that is still used in the MOSES package, please replace in the MOSES package the file `utils.py` with the one provided in this repository: **fixes\\utils.py**. The MOSES `utils.py` file should be located somewhere like:\r\n\r\n`C:\\Users\\<username>\\miniconda3\\lib\\site-packages\\moses\\metrics\\utils.py` or `miniconda\\lib\\python3.11\\site-packages\\molsets-1.0-py3.11.egg\\moses\\metrics\\utils.py`\r\n\r\nMore precisely the error should look like this:\r\n\r\n```bash\r\n_mcf.append(_pains, sort=True)['smarts'].values]\r\n...\r\nAttributeError: 'DataFrame' object has no attribute 'append'\r\n```\r\n\r\nThe trick is to replace this line (24) by:\r\n\r\n```python\r\n pd.concat([_mcf, _pains], sort=True)['smarts'].values]\r\n```\r\n\r\n**Remark:** The entire operation can be done through the command line by using sed:\r\n\r\n```bash\r\nsed -i \"24s/.*/\\t\\t\\tpd.concat([_mcf, _pains], sort=True)[\\o047smarts\\o047].values]/\" <path_to_moses_utils.py>\r\n```\r\n\r\n#### Error due to TopoNetX when running the tests\r\n\r\nInstall an old version of `TopoNetX`, by running for example the command:\r\n\r\n```bash\r\npip install git+https://github.com/pyt-team/TopoNetX.git@a389bd8bb11c731bb98d79da8392e3396ea9db8c\r\n```\r\n\r\nThen, replace the file `combinatorial_complex.py` of TopoNetX by the updated one provided in this repository: **fixes\\combinatorial_complex.py**\r\n\r\nThe file in TopoNetX should be located somewhere like:\r\n\r\n`C:\\Users\\<username>\\miniconda3\\Lib\\site-packages\\toponetx\\classes\\combinatorial_complex.py` or `miniconda\\lib\\python3.11\\site-packages\\toponetx\\classes\\combinatorial_complex.py`\r\n\r\n## Citation\r\n\r\nIf you use CCSD in your research or work, please consider citing it using the following BibTeX entry:\r\n\r\n```bibtex\r\nCarrel, A.
