No package example_robot_data

[wxmerkt]

I've installed crocoddyl from the robotpkg binaries and it is correctly sourced. The package robotpkg-example-robot-data is installed. However, I get:

Traceback (most recent call last):
  File "bipedal_walking_from_foot_traj.py", line 6, in <module>
    import example_robot_data
ImportError: No module named example_robot_data

I think you should upgrade robot-example-data. Did you do it?

[wxmerkt]

Yes... I just installed and it's the latest version on the binaries (2.0.0).

Also, the croccodyl version doesn't import any of the action models:

Traceback (most recent call last):
  File "jump.py", line 21, in <module>
    from crocoddyl import (ActionModelImpact, ActivationModelInequality, ActivationModelWeightedQuad,
ImportError: cannot import name ActionModelImpact

Is it possible that the build server hasn't released the new binaries yet?

[cmastalli]

@nim65s can tell you more about the binary release. I didn't try it myself yet.

There are few classes that haven't been release yet, e.g.:

• ActionModelImpact, ImpactModel3D, ImpactModel6D
• ActivationModelInequality,
• SolverFDDP, among others.

We tagged this version 0.9.0 because there is not yet everything there.

Regarding the examples and notebooks, it almost everything working with the exception of:

• jump.py
• walk.py
• salto.py

The problem with these examples is we need to release some of the classes that I mentioned above.

Similarly @nim65s, the 2.0.0 tag on example-robot-data in the binaries does not contain the Python loader either.

@cmastalli thank you for the update! Looking forward to Guilhem's response and will re-try then.

[nim65s]

@wxmerkt Python loaders are available in robotpkg-pyXY-example-robot-data, depending of your major / minor version of python.

I am fixing the dependency from robotpkg-pyXY-crocoddyl to robotpkg-pyXY-example-robot-data right now.

[cmastalli]

I added in the README file the instruction of how to install the Python loaders in example-robot-data. This information also appears in the README file of Crocoddyl.

I believe this issue has been solved. If not, feel free to reopen it
