Stuck while rendering trajectory

[jeje910]

Hi,
I'm now suffering from the code stucking and would ask some help to deal with it.

The problem command is as below:
python -m alfred.gen.render_trajs

From debugging, I found that the lines below makes it get stuck

E.T./alfred/gen/render_trajs.py

Lines 272 to 288 in 92ee237

	lock = threading.Lock()
	if args.num_threads > 0:
	# start threads
	threads = []
	for worker_id in range(min(args.num_threads, len(traj_list))):
	thread = threading.Thread(
	target=start_worker,
	args=(worker_id, traj_list, args, lock, processed_files_path))
	threads.append(thread)
	thread.start()
	time.sleep(1)
	for thread in threads:
	thread.join()
	else:
	# run in the main thread
	start_worker(0, traj_list, args, lock, processed_files_path)
	return

More precisely, the code stuck while performing the lines below.

E.T./alfred/env/thor_env.py

Lines 65 to 76 in 92ee237

	super().reset(scene_name)
	event = super().step(dict(
	action='Initialize',
	gridSize=grid_size,
	cameraY=camera_y,
	renderImage=render_image,
	renderDepthImage=render_depth_image,
	renderClassImage=render_class_image,
	renderObjectImage=render_object_image,
	visibility_distance=visibility_distance,
	makeAgentsVisible=False,
	))

It stuck due to thorEnv so I searched some issue seems related.

There is no error but the simulator just stop on some timestamp and don't move more than a day..
It would be very appreciate if you help

Hi, the issue was just from the versions of modules.
I just re-create the virtual environment with with older modules and works well! (Used some version history logs of moudles)
I'll close the issue myself!

Thank you I had this problem too

[jiahai-feng]

What modules specifically? I'm also stuck on this!

[Samuel-Fipps]

I don't know which one but here is my list with my versions.
added seed packages: ai2thor==2.1.0, estraces==1.8.0, etaprogress==1.1.1, filelock==3.0.0, gtimer==1.0.0b5, jsonpickle==1.5.2, lmdb==1.3.0, munch==2.5.0, numpy==1.21.6, pip==22.2.2, py_cpuinfo==8.0.0, sacred==0.8.2, scared==0.9.1, setuptools==65.3.0, tensorboardX==1.8, torch==1.7.1+cu110, torchaudio==0.7.2, torchvision==0.8.2+cu110, trsfile==0.3.2, wheel==0.37.1

Hi @jeje910, could you please share the commit for older modules that you used? I am also facing the same issue.
Tried the versions which @Samuel-Fipps shared but had no luck.

[jeje910]

In my case, torch version was the matter but not sure. I downloaded the torch==1.6.0 somehow which is not supported anymore and worked well. But, not only the torch version but also other modules also had conflict with it so I cannot specify which module should be changed.. And Unfortunately, I didn't saved the virtual environment config so that I could not help you that much.. Sorry for the late reply and poor help.

@jeje910 I installed torch==1.1.0 which is old but the torch is not compatible with my gpu. Which gpu did you run it on? What is the workaround this? I have RTX3060.

torch 1.1.0 which is required for ai2thor==2.1.0 is not compatible for sm_86.

[jeje910]

In case of ET model, I ran my code on RTX3090 and worked well. (But the environment seems not that proper..)

[Samuel-Fipps]

Okay I finally went and found the problem. You need.
pip install Werkzeug==2.0.3
