**Hello community, I am trying to perform the UR3 training about end-effector positioning with the use of Stable-Baselines.
I am using Ubuntu 20.04
ROS noetic
python 3.8
Stable-Baselines3 = 2.0.0.0
tf = 2
I have seen in the Stable-Baselines example that it uses the previous version, but when using python 3.8 it is not possible to install TF=1.15 for Stable-Baselines.
So I chose to use Stable-Baselines3, when I run the code for the MiR100 robot it works fine.
The problem is when I change the environment to UR3 "EndEffectorPositioningURSim-v0", the simulation runs in gazebo fine, but when I run the line "model.learn(total_timesteps=15000)" it generates the following error
can anyone help me how can I fix the error, or any recommendation of versions in which stable baseline works well.
I have thought about moving everything to ubuntu 18.04, but the idea is to keep developing some new not to go backwards.**
