Pure static Lie groups in Numpy, Jax, and C++

PyMLG - Matrix Lie groups with Numpy, Jax, and C++ implementations!

An instantiation-free python package for common matrix Lie group operations implemented as pure static classes. Using pure static classes keeps the usage extremely simple while still allowing for abstraction and inheritance. We do not introduce new objects with stateful behavior that must be learnt. Everything operates directly on arrays/tensors. This allows users to implement their own more sophisticated objects using these classes as back-end mathematical implementations.

Installation

Begin by cloning this repo somewhere. To install, go to the clone directory and run

pip install -e .

Documentation

Documentation can be found here: https://decargroup.github.io/pymlg

Example

from pymlg import SE3 
import numpy as np

# Random pose
T = SE3.random()

# R^n to group directly (using "Capital" notation)
x = np.array([0.1, 0.2, 0.3, 4, 5, 6])
T = SE3.Exp(x)

# Group to R^n directly
x = SE3.Log(T)

# Wedge, vee
Xi = SE3.wedge(x)
x = SE3.vee(Xi)

# Actual exp/log maps 
T = SE3.exp(Xi)
Xi = SE3.log(T)

# Adjoint matrix representation of group element
A = SE3.adjoint(T)

# Adjoint representation of algebra element
ad = SE3.adjoint_algebra(Xi)

# Inverse of group element
T_inv = SE3.inverse(T)

# Group left/right jacobians, and their inverses
J_L = SE3.left_jacobian(x)
J_R = SE3.right_jacobian(x)
J_L_inv = SE3.left_jacobian_inv(x)
J_R_inv = SE3.right_jacobian_inv(x)

# ... and more.

Using Numpy/C++/Jax

To explicitly access pure numpy implementations use

from pymlg.numpy import SO2, SO3, SE2, SE3, SE23

To explicitly access classes which internally use C++ use

from pymlg.cpp import SO3, SE3, SE23

To explicitly access Jax implementations use

from pymlg.jax import SE2

Currently, only SO3, SE3, and SE23 are implemented in C++, with the functions accepting and returning numpy arrays. They are also the default internal implementations when simply using from pymlg import SO3, SE3, SE23. For the JAX implementation, the return types will be jax.numpy arrays. All operations in the jax implementation can be JIT-compiled.

For all implementations (jax, numpy, C++), the user API is exactly the same! This means that by changing the import statement the example still works.

Note: functions which output "vectors", such as SE2.Log(T) all return a 2D numpy array with dimensions (n, 1).

Running Tests

If you use VS Code, you should be able to enable the VS Code testing feature using pytest. Otherwise, you can run tests from the command line when inside this folder using

pytest tests

Credit to UTIAS's STARS group

Some specific implementations came from the UTIAS STARS Lie group package.. We wanted a different API and variable ordering, which led to us making our own package. Eventually, this repo evolved to contain more groups, as well as Jax and C++ implementations.

pymlg's Issues

Bug in SE2.from_components

This should be size==1 not size==3

https://github.com/decargroup/pymlg/blob/main/pymlg/numpy/se2.py#L27

some errors in PyCharm

After installing the pymlg package in Pycharm, running standard_test.py will show that pymlg.cpp.impl does not exist in the wrapper.py file, with a detailed error message：
C:\Users\81956\AppData\Local\Microsoft\WindowsApps\python3.11.exe D:\pymlg\tests\standard_tests.py
Traceback (most recent call last):

File "D:\pymlg\pymlg\cpp\wrapper.py", line 6, in
from ._impl import SO3 as SO3cpp
ModuleNotFoundError: No module named 'pymlg.cpp._impl'
I hope the author can provide a solution, thank you very much！

Installation problem

Hello,

I am trying to install this library into my environment, and I having some problems.

First, I tried
pip install git+https://github.com/decargroup/pymlg,
and I got some errors.

I then tried to download this repo and, from the main folder, do
pip install -e.
as specified in the docs, but it also failed.

The messages of the errors are shown below.
Does anyone know how to fix this?

Thanks in advance

              ********************************************************************************
              An error happened while installing `pymlg` in editable mode.
     
              The following steps are recommended to help debug this problem:
     
              - Try to install the project normally, without using the editable mode.
                Does the error still persist?
                (If it does, try fixing the problem before attempting the editable mode).
              - If you are using binary extensions, make sure you have all OS-level
                dependencies installed (e.g. compilers, toolchains, binary libraries, ...).
              - Try the latest version of setuptools (maybe the error was already fixed).
              - If you (or your project dependencies) are using any setuptools extension
                or customization, make sure they support the editable mode.
     
              After following the steps above, if the problem still persists and
              you think this is related to how setuptools handles editable installations,
              please submit a reproducible example
              (see https://stackoverflow.com/help/minimal-reproducible-example) to:
