-# Python Wrapper
-
-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
-
-- 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.
-
-- Build GTSAM and the wrapper with `make`.
-
-- 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.
-
-- 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 <GTSAM_CYTHON_INSTALL_PATH>
-  python -m unittest discover
-  ```
-
-## Utils
-
-TODO
-
-## Examples
-
-TODO
-
-## Writing Your Own Scripts
-
-See the tests for examples.
-
-### 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
-    the flag order='F'. And you always get column-major matrices back.
-    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`
-
-- 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 Custom GTSAM-based Project
-
-Please refer to the template project and the corresponding tutorial available [here](https://github.com/borglab/GTSAM-project-python).
-
-## 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?)
-- [ ] inner namespaces ==> inner packages?
-- [ ] Wrap fixed-size Matrices/Vectors?
-
-### Completed/Cancelled:
-
-- [x] Fix Python tests: don't use " import <package> \* ": Bad style!!! (18-03-17 19:50)
-- [x] Unit tests for cython wrappers @done (18-03-17 18:45) -- simply compare generated files
-- [x] Wrap unstable @done (18-03-17 15:30)
-- [x] Unify cython/GTSAM.h and the original GTSAM.h @done (18-03-17 15:30)
-- [x] 18-03-17: manage to unify the two versions by removing std container stubs from the matlab version,and keeping KeyList/KeyVector/KeySet as in the matlab version. Probably Cython 0.25 fixes the casting problem.
-- [x] 06-03-17: manage to remove the requirements for default and copy constructors
-- [ ] 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>.
-- [ ] Marginal and JointMarginal: revert changes @failed (17-03-17 11:00) -- Cython does need a default constructor! It produces cpp code like this: `GTSAM::JointMarginal __pyx_t_1;` Users don't have to wrap this constructor, however.
-- [x] Convert input numpy Matrix/Vector to float dtype and storage order 'F' automatically, cannot crash! @done (15-03-17 13:00)
-- [x] Remove requirements.txt - Frank: don't bother with only 2 packages and a special case for eigency! @done (08-03-17 10:30)
-- [x] CMake install script @done (25-11-16 02:30)
-- [ ] [REFACTOR] better name for uninstantiateClass: very vague!! @cancelled (25-11-16 02:30) -- lazy
-- [ ] forward declaration? @cancelled (23-11-16 13:00) - nothing to do, seem to work?
-- [x] wrap VariableIndex: why is it in inference? If need to, shouldn't have constructors to specific FactorGraphs @done (23-11-16 13:00)
-- [x] Global functions @done (22-11-16 21:00)
-- [x] [REFACTOR] typesEqual --> isSameSignature @done (22-11-16 21:00)
-- [x] Proper overloads (constructors, static methods, methods) @done (20-11-16 21:00)
-- [x] Allow overloading methods. The current solution is annoying!!! @done (20-11-16 21:00)
-- [x] Casting from parent and grandparents @done (16-11-16 17:00)
-- [x] Allow overloading constructors. The current solution is annoying!!! @done (16-11-16 17:00)
-- [x] Support "print obj" @done (16-11-16 17:00)
-- [x] methods for FastVector: at, [], ... @done (16-11-16 17:00)
-- [x] Cython: Key and size_t: traits<size_t> doesn't exist @done (16-09-12 18:34)
-- [x] KeyVector, KeyList, KeySet... @done (16-09-13 17:19)
-- [x] [Nice to have] parse typedef @done (16-09-13 17:19)
-- [x] ctypedef at correct places @done (16-09-12 18:34)
-- [x] expand template variable type in constructor/static methods? @done (16-09-12 18:34)
-- [x] NonlinearOptimizer: copy constructor deleted!!! @done (16-09-13 17:20)
-- [x] Value: no default constructor @done (16-09-13 17:20)
-- [x] ctypedef PriorFactor[Vector] PriorFactorVector @done (16-09-19 12:25)
-- [x] Delete duplicate methods in derived class @done (16-09-12 13:38)
-- [x] Fix return properly @done (16-09-11 17:14)
-- [x] handle pair @done (16-09-11 17:14)
-- [x] Eigency: ambiguous call: A(const T&) A(const Vector& v) and Eigency A(Map[Vector]& v) @done (16-09-11 07:59)
-- [x] Eigency: Constructor: ambiguous construct from Vector/Matrix @done (16-09-11 07:59)
-- [x] Eigency: Fix method template of Vector/Matrix: template argument is [Vector] while arugment is Map[Vector] @done (16-09-11 08:22)
-- [x] Robust noise: copy assignment operator is deleted because of shared_ptr of the abstract Base class @done (16-09-10 09:05)
-- [ ] Cython: Constructor: generate default constructor? (hack: if it's serializable?) @cancelled (16-09-13 17:20)
-- [ ] Eigency: Map[] to Block @created(16-09-10 07:59) @cancelled (16-09-11 08:28)

-// Strides:
-// Eigen and numpy differ in their way of dealing with strides. Eigen has the concept of outer and
-// inner strides, which are dependent on whether the array/matrix is row-major of column-major:
-//     Inner stride: denotes the offset between succeeding elements in each row (row-major) or column (column-major).
-//     Outer stride: denotes the offset between succeeding rows (row-major) or succeeding columns (column-major).
-// In contrast, numpy's stride is simply a measure of how fast each dimension should be incremented.
-// Consequently, a switch in numpy storage order from row-major to column-major involves a switch
-// in strides, while it does not affect the stride in Eigen.

+# Python Wrapper
+
+This is the Python wrapper around the GTSAM C++ library. We use our custom [wrap library](https://github.com/borglab/wrap) 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 `pyparsing(>=2.4.2)`, and `numpy(>=1.11.0)`. These can be installed as follows:
+
+  ```bash
+  pip install -r <gtsam_folder>/python/requirements.txt
+  ```
+
+## Install
+
+- Run cmake with the `GTSAM_BUILD_PYTHON` cmake flag enabled to configure building the wrapper. The wrapped module will be built and copied to the directory `<PROJECT_BINARY_DIR>/python`.
+
+- Build GTSAM and the wrapper with `make` (or `ninja` if you use `-GNinja`).
+
+- To install, simply run `make python-install` (`ninja 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.
+
+- You can also directly run `make python-install` without running `make`, and it will compile all the dependencies accordingly.
+
+## Unit Tests
+
+The Python toolbox also has a small set of unit tests located in the
+test directory. To run them:
+
+  ```bash
+  cd <GTSAM_SOURCE_DIRECTORY>/python/gtsam/tests
+  python -m unittest discover
+  ```

+See the tests for examples.
+
+### 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`, to avoid any conversion needed.
+  - Also, GTSAM expects _column-major_ matrices, unlike the default storage
+    scheme in numpy. But this is only performance-related as `pybind11` should translate them when needed. However, this will result a copy if your matrix is not in the expected type
+    and storage order.
+
+## Wrapping Custom GTSAM-based Project

+Please refer to the template project and the corresponding tutorial available [here](https://github.com/borglab/GTSAM-project-python).

-# WRAP README
 
-The wrap library wraps the GTSAM library into a MATLAB toolbox. 
+# WRAP
 
-It was designed to be more general than just wrapping GTSAM, but a small amount of GTSAM specific code exists in matlab.h, the include file that is included by the mex files. The GTSAM-specific functionality consists primarily of handling of Eigen Matrix and Vector classes.  
+The wrap library wraps the GTSAM library into a Python library or MATLAB toolbox.
+It was designed to be more general than just wrapping GTSAM. For notes on creating a wrap interface, see `gtsam.h` for what features can be wrapped into a toolbox, as well as the current state of the toolbox for GTSAM.
 
-For notes on creating a wrap interface, see gtsam.h for what features can be wrapped into a toolbox, as well as the current state of the toolbox for gtsam. For more technical details on the interface, please read comments in matlab.h
+## Prerequisites: Pybind11 and pyparsing
+
+1. This library uses `pybind11`, which is included as a subdirectory in GTSAM.
+2. The `interface_parser.py` in this library uses `pyparsing` to parse the interface file `gtsam.h`. Please install it first in your current Python environment before attempting the build.
+    ```
+    python3 -m pip install pyparsing
+    ```
+
+## GTSAM Python wrapper
+
+**WARNING: On macOS, you have to statically build GTSAM to use the wrapper.**
+
+1. Set `GTSAM_BUILD_PYTHON=ON` while configuring the build with `cmake`.
+1. What you can do in the `build` folder:
+    1. Just run python then import GTSAM and play around:
+        ```
+
+        import gtsam
+        gtsam.__dir__()
+        ```
+
+    1. Run the unittests:
+        ```
+        python -m unittest discover
+        ```
+    1. Edit the unittests in `python/gtsam/*.py` and simply rerun the test.
+    They were symlinked to `<build_folder>/gtsam/*.py` to facilitate fast development.
+        ```
+        python -m unittest gtsam/tests/test_Pose3.py
+        ```
+        - NOTE: You might need to re-run `cmake ..` if files are deleted or added.
+1. Do `make install` and `cd <gtsam_install_folder>/python`. Here, you can:
+    1. Run the unittests:
+        ```
+        python setup.py test
+        ```
+    2. Install `gtsam` to your current Python environment.
+        ```
+        python setup.py install
+        ```
+        - NOTE: It's a good idea to create a virtual environment otherwise it will be installed in your system Python's site-packages.
+
+
+## Old GTSAM Wrapper
+
+*Outdated note from the original wrap.*
+
+TODO: Update this.
+
+It was designed to be more general than just wrapping GTSAM, but a small amount of GTSAM specific code exists in `matlab.h`, the include file that is included by the `mex` files. The GTSAM-specific functionality consists primarily of handling of Eigen Matrix and Vector classes.
+
+For notes on creating a wrap interface, see `gtsam.h` for what features can be wrapped into a toolbox, as well as the current state of the toolbox for GTSAM. For more technical details on the interface, please read comments in `matlab.h`
 
 Some good things to know:
 
 OBJECT CREATION
 
-- Classes are created by special constructors, e.g., new_GaussianFactorGraph_.cpp.
-	These constructors are called from the MATLAB class @GaussianFactorGraph.
-	new_GaussianFactorGraph_ calls wrap_constructed in matlab.h, see documentation there
-	
+- Classes are created by special constructors, e.g., `new_GaussianFactorGraph_.cpp`.
+	These constructors are called from the MATLAB class `@GaussianFactorGraph`.
+	`new_GaussianFactorGraph_` calls wrap_constructed in `matlab.h`, see documentation there
+
 METHOD (AND CONSTRUCTOR) ARGUMENTS
 
 - Simple argument types of methods, such as "double", will be converted in the
-  mex wrappers by calling unwrap<double>, defined in matlab.h
+  `mex` wrappers by calling unwrap<double>, defined in matlab.h
 - Vector and Matrix arguments are normally passed by reference in GTSAM, but
-  in gtsam.h you need to pretend they are passed by value, to trigger the 
-  generation of the correct conversion routines unwrap<Vector> and unwrap<Matrix>
+  in `gtsam.h` you need to pretend they are passed by value, to trigger the
+  generation of the correct conversion routines `unwrap<Vector>` and `unwrap<Matrix>`
 - passing classes as arguments works, provided they are passed by reference.
 	This triggers a call to unwrap_shared_ptr

+Deepcopy support
+================
+
+Python normally uses references in assignments. Sometimes a real copy is needed
+to prevent changing all copies. The ``copy`` module [#f5]_ provides these
+capabilities.
+
+On Python 3, a class with pickle support is automatically also (deep)copy
+compatible. However, performance can be improved by adding custom
+``__copy__`` and ``__deepcopy__`` methods. With Python 2.7, these custom methods
+are mandatory for (deep)copy compatibility, because pybind11 only supports
+cPickle.
+
+For simple classes (deep)copy can be enabled by using the copy constructor,
+which should look as follows:
+
+.. code-block:: cpp
+
+    py::class_<Copyable>(m, "Copyable")
+        .def("__copy__",  [](const Copyable &self) {
+            return Copyable(self);

+        .def("__deepcopy__", [](const Copyable &self, py::dict) {
+            return Copyable(self);
+        }, "memo"_a);

+
+Pybind11 provides a ``py::kwonly`` object that allows you to implement
+the same behaviour by specifying the object between positional and keyword-only
+argument annotations when registering the function:
+
+.. code-block:: cpp
+
+    m.def("f", [](int a, int b) { /* ... */ },
+          py::arg("a"), py::kwonly(), py::arg("b"));

+Memory view
+===========
+
+For a case when we simply want to provide a direct accessor to C/C++ buffer
+without a concrete class object, we can return a ``memoryview`` object. Suppose
+we wish to expose a ``memoryview`` for 2x4 uint8_t array, we can do the
+following:
+
+.. code-block:: cpp
+
+    const uint8_t buffer[] = {
+        0, 1, 2, 3,
+        4, 5, 6, 7
+    };
+    m.def("get_memoryview2d", []() {
+        return py::memoryview::from_buffer(
+            buffer,                                    // buffer pointer
+            { 2, 4 },                                  // shape (rows, cols)
+            { sizeof(uint8_t) * 4, sizeof(uint8_t) }   // strides in bytes
+        );
+    })
+
+This approach is meant for providing a ``memoryview`` for a C/C++ buffer not
+managed by Python. The user is responsible for managing the lifetime of the
+buffer. Using a ``memoryview`` created in this way after deleting the buffer in
+C++ side results in undefined behavior.
+
+We can also use ``memoryview::from_memory`` for a simple 1D contiguous buffer:
+
+.. code-block:: cpp
+
+    m.def("get_memoryview1d", []() {
+        return py::memoryview::from_memory(
+            buffer,               // buffer pointer
+            sizeof(uint8_t) * 8   // buffer size
+        );
+    })
+
+.. note::
+
+    ``memoryview::from_memory`` is not available in Python 2.

-v2.3.1 (Not yet released)
+v2.5.0 (Mar 31, 2020)
 -----------------------------------------------------
 
-* TBA
+* Use C++17 fold expressions in type casters, if available. This can
+  improve performance during overload resolution when functions have
+  multiple arguments.
+  `#2043 <https://github.com/pybind/pybind11/pull/2043>`_.
+
+* Changed include directory resolution in ``pybind11/__init__.py``
+  and installation in ``setup.py``. This fixes a number of open issues
+  where pybind11 headers could not be found in certain environments.
+  `#1995 <https://github.com/pybind/pybind11/pull/1995>`_.
+
+* C++20 ``char8_t`` and ``u8string`` support. `#2026
+  <https://github.com/pybind/pybind11/pull/2026>`_.
+
+* CMake: search for Python 3.9. `bb9c91
+  <https://github.com/pybind/pybind11/commit/bb9c91>`_.
+
+* Fixes for MSYS-based build environments.

+How can I properly handle Ctrl-C in long-running functions?
+===========================================================
+
+Ctrl-C is received by the Python interpreter, and holds it until the GIL
+is released, so a long-running function won't be interrupted.
+
+To interrupt from inside your function, you can use the ``PyErr_CheckSignals()``
+function, that will tell if a signal has been raised on the Python side.  This
+function merely checks a flag, so its impact is negligible. When a signal has
+been received, you must either explicitly interrupt execution by throwing
+``py::error_already_set`` (which will propagate the existing
+``KeyboardInterrupt``), or clear the error (which you usually will not want):
