TimeOut error when attempting to run pre-trained RoboThor model checkpoint

[dtch1997]

Problem

Unable to run pre-trained RoboThor model checkpoint

Steps to reproduce

Followed all instructions at https://allenact.org/tutorials/running-inference-on-a-pretrained-model/ Then ran:

PYTHONPATH=. python allenact/main.py \
training_a_pointnav_model \
-o pretrained_model_ckpts/robothor-pointnav-rgb-resnet/ \
-b projects/tutorials \
-c pretrained_model_ckpts/robothor-pointnav-rgb-resnet/checkpoints/PointNavRobothorRGBPPO/2020-08-31_12-13-30/exp_PointNavRobothorRGBPPO__stage_00__steps_000039031200.pt \
--eval

Got the error:

Expected behavior

Able to run inference and save metrics to tensorboard.
