To Reproduce
cd /code/cameranetwork$ cd scripts_client/
python start_local.py -d "/VISL2_net/amitibo/experiment_2017_02-03/"

According to anishathalye/neural-style#47 this is due to corrupted file. Should download it again and try again.

On my station it works for the given camera folder that I have.

Using Scipy version 1.2.1

Anyways, this is the code that is responsible:

cameranetwork/CameraNetwork/controller.py

Lines 212 to 222 in ac9d513

	# Sky mask
	#
	if os.path.exists(gs.MASK_PATH):
	try:
	self.sky_mask_base = sio.loadmat(gs.MASK_PATH)['mask_base']
	except Exception, e:
	logging.error("Failed loading sky mask.")
	logging.error("{}".format(traceback.print_exc()))
	self.sky_mask_base = None
	else:
	self.sky_mask_base = None

and mask path is given by

cameranetwork/CameraNetwork/global_settings.py

Line 421 in ac9d513

MASK_PATH = os.path.join(HOME_PATH, 'mask_img.mat')

I ran start_local with only some of the cameras (111c 112b 115b 120) and didn't experience any issues.
However, the others from here ['cam_110bL', 'cam_117L', 'cam_109bL', 'cam_115bL', 'cam_111cL', 'cam_119bL', 'cam_120L', 'cam_112bL'] did raise for one of them. this further suggests a corrupted file in one of them..
