# Python Wrapper
This is the Cython/Python wrapper around the GTSAM C++ library.
This is the Python wrapper around the GTSAM C++ library. We use Cython to generate the bindings to the underlying C++ code.
## Requirements
- If you want to build the GTSAM python library for a specific python version (eg 3.6),
use the `-DGTSAM_PYTHON_VERSION=3.6` option when running `cmake` otherwise the default interpreter will be used.
- If the interpreter is inside an environment (such as an anaconda environment or virtualenv environment),
then the environment should be active while building GTSAM.
- This wrapper needs `Cython(>=0.25.2)`, `backports_abc(>=0.5)`, and `numpy(>=1.11.0)`. These can be installed as follows:
```bash
pip install -r <gtsam_folder>/cython/requirements.txt
```
- For compatibility with GTSAM's Eigen version, it contains its own cloned version of [Eigency](https://github.com/wouterboomsma/eigency.git),
named `gtsam_eigency`, to interface between C++'s Eigen and Python's numpy.
## Install
- if you want to build the gtsam python library for a specific python version (eg 2.7), use the `-DGTSAM_PYTHON_VERSION=2.7` option when running `cmake` otherwise the default interpreter will be used.
- If the interpreter is inside an environment (such as an anaconda environment or virtualenv environment) then the environment should be active while building gtsam.
- This wrapper needs Cython(>=0.25.2), backports_abc>=0.5, and numpy. These can be installed as follows:
- Run cmake with the `GTSAM_INSTALL_CYTHON_TOOLBOX` cmake flag enabled to configure building the wrapper. The wrapped module will be built and copied to the directory defined by `GTSAM_CYTHON_INSTALL_PATH`, which is by default `<PROJECT_BINARY_DIR>/cython` in Release mode and `<PROJECT_BINARY_DIR>/cython<CMAKE_BUILD_TYPE>` for other modes.
```bash
pip install -r <gtsam_folder>/cython/requirements.txt
```
- Build GTSAM and the wrapper with `make`.
- For compatibility with gtsam's Eigen version, it contains its own cloned version of [Eigency](https://github.com/wouterboomsma/eigency.git),
named **gtsam_eigency**, to interface between C++'s Eigen and Python's numpy.
- To install, simply run `make python-install`.
- The same command can be used to install into a virtual environment if it is active.
- **NOTE**: if you don't want GTSAM to install to a system directory such as `/usr/local`, pass `-DCMAKE_INSTALL_PREFIX="./install"` to cmake to install GTSAM to a subdirectory of the build directory.
- Build and install gtsam using cmake with `GTSAM_INSTALL_CYTHON_TOOLBOX` enabled.
The wrapped module will be installed to `GTSAM_CYTHON_INSTALL_PATH`, which is
by default: `<your CMAKE_INSTALL_PREFIX>/cython`
- To use the library without installing system-wide: modify your `PYTHONPATH` to include the `GTSAM_CYTHON_INSTALL_PATH`:
```bash
export PYTHONPATH=$PYTHONPATH:<GTSAM_CYTHON_INSTALL_PATH>
```
- To install system-wide: run `make install` then navigate to `GTSAM_CYTHON_INSTALL_PATH` and run `python setup.py install`
- (the same command can be used to install into a virtual environment if it is active)
- note: if you don't want gtsam to install to a system directory such as `/usr/local`, pass `-DCMAKE_INSTALL_PREFIX="./install"` to cmake to install gtsam to a subdirectory of the build directory.
- if you run `setup.py` from the build directory rather than the installation directory, the script will warn you with the message: `setup.py is being run from an unexpected location`.
Before `make install` is run, not all the components of the package have been copied across, so running `setup.py` from the build directory would result in an incomplete package.
- You can also directly run `make python-install` without running `make`, and it will compile all the dependencies accordingly.
## Unit Tests
The Cython toolbox also has a small set of unit tests located in the
test directory. To run them:
```bash
cd <your GTSAM_CYTHON_INSTALL_PATH>
python -m unittest discover
```
```bash
cd <GTSAM_CYTHON_INSTALL_PATH>
python -m unittest discover
```

### Some Important Notes:
- Vector/Matrix:
+ GTSAM expects double-precision floating point vectors and matrices.
Hence, you should pass numpy matrices with dtype=float, or 'float64'.
+ Also, GTSAM expects *column-major* matrices, unlike the default storage
scheme in numpy. Hence, you should pass column-major matrices to gtsam using
- GTSAM expects double-precision floating point vectors and matrices.
Hence, you should pass numpy matrices with `dtype=float`, or `float64`.
- Also, GTSAM expects _column-major_ matrices, unlike the default storage
scheme in numpy. Hence, you should pass column-major matrices to GTSAM using
the flag order='F'. And you always get column-major matrices back.
For more details, see: https://github.com/wouterboomsma/eigency#storage-layout---why-arrays-are-sometimes-transposed
+ Passing row-major matrices of different dtype, e.g. 'int', will also work
For more details, see [this link](https://github.com/wouterboomsma/eigency#storage-layout---why-arrays-are-sometimes-transposed).
- Passing row-major matrices of different dtype, e.g. `int`, will also work
as the wrapper converts them to column-major and dtype float for you,
using numpy.array.astype(float, order='F', copy=False).
However, this will result a copy if your matrix is not in the expected type
and storage order.
- Inner namespace: Classes in inner namespace will be prefixed by <innerNamespace>_ in Python.
Examples: noiseModel_Gaussian, noiseModel_mEstimator_Tukey
- Inner namespace: Classes in inner namespace will be prefixed by <innerNamespace>\_ in Python.
Examples: `noiseModel_Gaussian`, `noiseModel_mEstimator_Tukey`
- Casting from a base class to a derive class must be done explicitly.
Examples:
```Python
noiseBase = factor.noiseModel()
noiseGaussian = dynamic_cast_noiseModel_Gaussian_noiseModel_Base(noiseBase)
```
## Wrapping Your Own Project That Uses GTSAM
Examples:
- Set PYTHONPATH to include ${GTSAM_CYTHON_INSTALL_PATH}
+ so that it can find gtsam Cython header: gtsam/gtsam.pxd
```python
noiseBase = factor.noiseModel()
noiseGaussian = dynamic_cast_noiseModel_Gaussian_noiseModel_Base(noiseBase)
```
- In your CMakeList.txt
```cmake
find_package(GTSAM REQUIRED) # Make sure gtsam's install folder is in your PATH
set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH}" "${GTSAM_DIR}/../GTSAMCMakeTools")

## KNOWN ISSUES
- Doesn't work with python3 installed from homebrew
- size-related issue: can only wrap up to a certain number of classes: up to mEstimator!
- Guess: 64 vs 32b? disutils Compiler flags?
- Bug with Cython 0.24: instantiated factor classes return FastVector<size_t> for keys(), which can't be casted to FastVector<Key>
- Upgrading to 0.25 solves the problem
- Need default constructor and default copy constructor for almost every classes... :(
- support these constructors by default and declare "delete" for special classes?

### TODO
- [ ] allow duplication of parent' functions in child classes. Not allowed for now due to conflicts in Cython.
- [ ] a common header for boost shared_ptr? (Or wait until everything is switched to std::shared_ptr in gtsam?)

- [ ] 25-11-16: Try to unify but failed. Main reasons are: Key/size_t, std containers, KeyVector/KeyList/KeySet. Matlab doesn't need to know about Key, but I can't make Cython to ignore Key as it couldn't cast KeyVector, i.e. FastVector<Key>, to FastVector<size_t>.
