EOFError and ConnectionResetError in the multiprocessing connection.py

[feliks3]

After I installed habitat-sim, habitat-lab and VLN-CE in the README.md successfully, and run the command "python run.py --exp-config vlnce_baselines/config/rxr_configs/rxr_cma_en.yaml --run-type train", I got this error.

Did I do something wrong?

This could be for many different reasons. Have you been able to successfully run the Habitat-Lab example script? The multiprocessing error could be hiding the real issue. Switching from habitat.VectorEnv to habitat.ThreadedVectorEnv in the construct_envs function should provide a more useful message. One reason I've seen this error is from having wrong file paths in the config.

I also got the same error. I looked at the previous related content and thought there might be a problem with the dataset. Could you please give me a solution?
