display connection Issues when trying to run training based on allenact

[OfekGlick]

Hi!
I have tried running locally the command:
allenact manipulathor_baselines/armpointnav_baselines/experiments/ithor/ -o experiment_output -s 1

and am receiving the following error:
Process ForkServerProcess-1:1: Traceback (most recent call last): File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/multiprocessing/process.py", line 314, in _bootstrap self.run() File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/multiprocessing/process.py", line 108, in run self._target(*self._args, **self._kwargs) File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/site-packages/allenact/algorithms/onpolicy_sync/vector_sampled_tasks.py", line 346, in _task_sampling_loop_worker sp_vector_sampled_tasks = SingleProcessVectorSampledTasks( File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/site-packages/allenact/algorithms/onpolicy_sync/vector_sampled_tasks.py", line 897, in __init__ self._vector_task_generators: List[Generator] = self._create_generators( File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/site-packages/allenact/algorithms/onpolicy_sync/vector_sampled_tasks.py", line 1116, in _create_generators if next(generators[-1]) != "started": File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/site-packages/allenact/algorithms/onpolicy_sync/vector_sampled_tasks.py", line 962, in _task_sampling_loop_generator_fn current_task = task_sampler.next_task() File "/home/clair02/PycharmProjects/ithor_training/manipulathor/ithor_arm/ithor_arm_task_samplers.py", line 360, in next_task self.env = self._create_environment() File "/home/clair02/PycharmProjects/ithor_training/manipulathor/ithor_arm/ithor_arm_task_samplers.py", line 78, in _create_environment env = ManipulaTHOREnvironment( File "/home/clair02/PycharmProjects/ithor_training/manipulathor/ithor_arm/ithor_arm_environment.py", line 113, in __init__ self.start(None) File "/home/clair02/PycharmProjects/ithor_training/manipulathor/ithor_arm/ithor_arm_environment.py", line 155, in start self.controller = self.create_controller() File "/home/clair02/PycharmProjects/ithor_training/manipulathor/ithor_arm/ithor_arm_environment.py", line 130, in create_controller controller = Controller(**self.env_args, commit_id=MANIPULATHOR_COMMIT_ID) File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/site-packages/ai2thor/controller.py", line 513, in __init__ self._build = self.find_build(local_build, commit_id, branch, platform) File "/home/clair02/miniconda3/envs/ithor_training/lib/python3.10/site-packages/ai2thor/controller.py", line 1352, in find_build raise Exception("\n".join(error_messages)) Exception: The following builds were found, but had missing dependencies. Only one valid platform is required to run AI2-THOR. Platform Linux64 failed validation with the following errors: Invalid display: :0.0. Failed to connect Can't connect to display ":0.0": [Errno 111] Connection refused Linux64 requires a X11 server to be running with GLX. The following valid displays were found :1.0, :2.0

For every process that isn't the first process.
I suspect that the first process is connecting to display :0 and then the rest of the process can't connect to the same display.
I have tried inspecting the problem but could not find a solution. Do you have any idea how this could be resolved?

Thanks for this incredible framework!
