sybrenstuvel / python-rvo2 Goto Github PK

Is there a reason this package is not on PyPi? If not then this is something that I'd like to help with.

Do you have the implementation of ORCA for non-holonomic robots?
Or do you know anyone who has worked on this?
Your help will be appreciated!

Thanks in Advance

Hi, thanks for your contribution.

When I tried to install pip install ~, some error occurs like following:

I have the following problem when I try to build or install. Apparently, everything works well until it tries to build the rvo2 extension:

In the example in README.md, the time step needs to be 1.0 / 60 because 1 / 60 is interpreted as 0 and thus the simulation does not progress.

I get this error when I import rvo2, how do I fix it? Thanks!

Hello Sybren,

Thank you for making the RVO2 code available in python!

However, I found a small bug and would appreciate if you could fix it:
In rvo.pyx, the destructor of RVOSimulator class is missing. This causes memory leak because an RVOSimulator object contains other objects, such as Agents, Obstacles, kdTree, etc. For this reason, the destructor of RVOSimulator is overwritten in the original C++ code and we must export the destructor to Python in rvo.pyx.

Please add the following line under cdef class PyRVOSimulator in line 79:
def __dealloc__(self): del self.thisptr

Howdy!
I'm brand new to this RVO2 library, but I'm wondering if you could answer a question, namely:

I have some Agents that need to animate along a predetermined animation path, that is, the can't participate in the "reciprocal" part of RVO; for the other Agents, these are basically Dynamic Obstacles.

Is there some way to set the Agent parameters to make something like this happen? I'm considering turning down the time horizon for the "obstacles" and maybe turning it up for the "avoiders", or just resetting the obstacle agent's position each step.

I thought that RVO supported setting a weight, i.e. 0.5 which had the effect of having each agent get out of the way of the other with equal effort. I was hoping I could find a place to set the weight to 1.0 for my dynamic obstacle objects.

I realize that this is just the home of the Python bindings for the RVO2 library - but I figure you're also expert users!

Thanks in advance

Hi, I was wondering, can this be used for RVO2-3D as well? How can I set it up so that it does?

Hi,
I am facing this error while building on Windows after running the command python setup.py build. Any idea how to go about it?

Firstly, cynton new version is installing but the version mentioned in requirement can't. After that executing "python setup.py build" is creating below error. Any suggestion will be helpful.

A call to processObstacles does not appear in the example code.

Is there a simple way to install Python-RVO2 for Windows? I faced the problems on linking stage.

RVO.lib(RVOSimulator.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '2' doesn't match value '0' in rvo2.obj

and

python36.lib(python36.dll) : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'

It seems msbuild generates project in debug configuration and for x86 architecture by default. How can I fix it? Thnx

I use Windows 10, Python 3.6 (Anaconda) and VC++ 14 (as recommended).

Hello, I meet a compilation error in ubuntu 18.04. and I hope someone could help me.

At first, I get a similar error with #15.
And I try to delete the empty build directory. Later, I meet another similar error.

why this error is happening ?

Hi, I use this package as a baseline for my own method. But, when I run my script, there has an error as follows:
AttributeError: 'rvo2.PyRVOSimulator' object has no attribute 'setAgentCollabCoeff'
I hope u can help me to solve this issue . Thank u so much ..

My robot is a non-holonomic robot, which can only move forward and rotate, but cannot move sideways. But I looked at the example.py file and found that the robot of the simulation simulator is a holonomic robot. How can I modify it into a holonomic robot?

I followed the instruction in the installment for Mac OS but still failed. The version of my system is 10.12.6.

Here is the error message:

I don't know if I'm missing something or if the functionality was not added , please clarify.

I have both Cmake and Cython (recommended version) installed. However, when I execute the command

python setup.py build

I get the following error

The key point I noticed that is undefined reference to aligned_alloc@GLIBC_2.16 and I also tried to search this but nothing got. Questions about this error has been many years ago, seems this rarely happens.

Actually I'm not that familar with CMake side, so maybe this is a stupid question. But if someone has meet the same problem please teach me how to solve it. So grateful!

System Info

• OS: Pop!_OS 21.10 x86_64
• Kernel: 5.16.11-76051611-generic
• libstdc++ Version: /usr/lib32/libstdc++.so.6 -> libstdc++.so.6.0.29
• g++ -dumpversion: 9.3.0
• Conda Version: 4.10.3
• Conda Env Python Version: 3.6

What I tried

1. Reinstall conda and conda env: the same problem happens;
2. Do not use conda env, instead of using system python env;
3. Upgrade system, including g++ and other libs;

What I guess

1. Conda's problem, maybe the Cython has some conflict with conda env?
2. Some out-of-date lib soft links, maybe can be fixed manually.

Sharing any ideas about this would be welcome and I would be so grateful.

I run "python setup.py install", but it can not work.

Hi,
I followed your instructions but having an import error when i run the python script.

I initially had a problem with setup.py install and hence did the whole setup in a virtual environment.

Can you please let me know what could be the problem ?
