Dataset problem

[monicapina]

Hi! After having installed all the necessary requirements to be able to use the repository on my pc, I have tried to run the code as described in the help files. However I get this error that seems to be related to a dataset , and I can't find a way to fix it.

Thanks in advance.

It means you don't have the "turtle_room" dataset to be able to run the experiment. Can you try running dmhouse experiments? They use simulated environment (DeepMind Lab). Alternatively, I can provide you with our "turtle_room" dataset if you want.

If it is not too much trouble, I would like you to provide me with "turtle_room" dataset, although I will try with dmhouse experiments as well..

Thanks and sorry for bothering you.

I am sorry it took me so long. The dataset can be downloaded here: https://storage.googleapis.com/robot-visual-navigation-datasets/turtle_room_grid_compiled.hdf5

Hi, I got the same problem and solved this problem by using the .hdf5 file you provided. However, another new issue occurs.

[jkulhanek]

Please post the exact command you used.

[AgentEXPL]

The command was " python train.py turtlebot ". I guess the issue may be caused by the following line. https://github.com/jkulhanek/robot-visual-navigation/blob/ddc63df38d326e9225981bf89608043c77d950e8/python/trainer.py#L144

If " model = Model(self.env.observation_space.spaces[0].spaces[0].shape[1], self.env.single_action_space.n)" was used, the issue disappeared and the code works without any errors. But I'm not sure whether this is the correct solution.

[jkulhanek]

Yes, it is the correct solution. I don’t know, how this could have happened, because the code definitely worked at the point of writing it. It might be the case that the older gym version didn’t use batch shape in VectorEnv observation shape? It will likely be in other places like test-env.py

[AgentEXPL]

Thanks for your kind confirmation.
