Calling controller reset was hung

[hcv1027]

I just modify the example code from the document with different scene. I found that there are lots of scene will just hang, never load successfully. (More than 10 minutes). In success case, it just takes no more than 3 seconds.
For example, controller.reset('FloorPlan478') takes more than 17 minutes, and still locked at this line , but controller.reset('FloorPlan206') will complete immediately. Here is my code:

import ai2thor.controller
import cv2
import numpy as np
import random

controller = ai2thor.controller.Controller()
controller.start()

# Kitchens: FloorPlan1 - FloorPlan30
# Living rooms: FloorPlan201 - FloorPlan230
# Bedrooms: FloorPlan301 - FloorPlan330
# Bathrooms: FloorPLan401 - FloorPlan430
scene_name = 'FloorPlan' + str(random.randint(1, 530))
print("scene name: {}".format(scene_name))
controller.reset(scene_name)
print('initialize')
controller.step(
    dict(action='Initialize', gridSize=0.25, renderDepthImage=True))
event = controller.step(dict(action='MoveAhead'))
img = event.depth_frame
img = img / 5000 * 255
cv2.imshow('img', img.astype(np.uint8))
cv2.waitKey(0)

My hardward is Lenovo T460

I run the code in docker. Any idea of how to fix this?

There is no FloorPlan478. The maximum FloorPlan number is 430. Can you send us another scene number that hangs?

Hi @roozbehm FloorPlan113 will hang too. Actually, almost all will hang in my environment.

There is no FloorPlan113 either. Please refer to the range in the code you copy pasted above (the comments). You are choosing a random number between 1 and 530. Most of those numbers are not in the range.

Hi @roozbehm, I'm sorry. It's my careless, I did not notice that the number is not continuous. Thanks for your reply.
