Environment

Hi @dnovischi, we are aware that master only supports the 6.0 version, while the last Ignition Gazebo release is 6.1^1.

Waiting for a new release, you can install the project from its Nightly channel.

diegoferigo commented 3 years ago

I noted that you used conda to install the dependencies. We are in the process to package this project in conda-forge, if you're interested you can follow https://github.com/conda-forge/staged-recipes/pull/16582.

Thanks.

diegoferigo commented 3 years ago

I'll keep this issue open so that it has visibility in case other users try to install the Stable channel with the most recent Ignition Gazebo. I'll close it as soon as a new release will be rolled out.

dnovischi commented 3 years ago

That's probably for the best until migration. I can confirm that it works with nightly.

When I tried to install with the Nightly version, there was TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases which is started from gym_ignition_environments.

How can I fix it?
