Error in /examples/imitation/trajectory_reproduction_kuka_dmp.py #59

Closed deepakraina99 closed 3 years ago

deepakraina99 commented 3 years ago

When I run this file, first I record the trajectory using ctrl+r and then by pressing shift+r, it fails to execute and gives the following error:

TypeError: Expecting an instance of `Action`, np.array, or a list of the previous ones, but got instead: <class 'numpy.ndarray'>

Please help.

Hi,

This code has been tested in several machines with different configurations without reporting the same error. May you please provide the python version you use, Linux machine, and other dependencies? Without this, it is very hard for us to get where this error comes from.

Hi, thanks for your response. I am using python 3.8.5 and use Ubuntu 20.04.2 LTS OS. I have also attached the list of packages in my environment.

packages_in_env.txt

deepakraina99 commented 3 years ago

This issue is resolved by changing line 49 of this code to env = Env(world, state, actions=action) I have proposed the changes also.

Thanks, @lrozo for your support.
