how to install and use openrave in python3

[WenzheHe]

I tried to install openrave in python3.6.9, but always failed. Just a few days ago, I saw someone said that now openrave could be install in python3 in another issue, but I didn't any offcial documentation. Could anyone show me how to install openrave in python3? Thanks for help!!

I have the same question. @WenzheHe did you find any answer for this? I want to install openrave on ubuntu 22.04. I assume you did try the same thing, right?

Now github action is implemented, which uses Python3. It targets Ubunutu 20, but I remember Ubuntu 22 installation is quite similar.

@cielavenir could you please elaborate more? a link to " github action " and the installation guide would be super helpful. thanks

@cielavenir I just follow the installation guide you provided a few days ago. Unfortunately, I met several problems, which I list below: [1]python3 -m pip install IPython==8.14.0 # ERROR: Could not find a version that satisfies the requirement IPython==8.14.0, I install IPython==8.13.0 instead.

make error

make: *** [Makefile:130: all] Error 2

I test this installation guide in Ubuntu-20.04, Python-3.8.10, GCC-9.4.0. In addition, I tested the installation guide to install the master branch of openrave.

@aminmajdi hello, have you successfully installed openrave with python 3 and Ubuntu20?

[cielavenir]

why don't you use docker image: https://hub.docker.com/repository/docker/cielavenir/openrave/tags?page=1&ordering=last_updated

source: https://github.com/cielavenir/dockerfiles/tree/master/openrave
