I have installed NeuralTalk2 and, to the best of my knowledge, all dependencies. I am running Ubuntu 14.04 on VMware Workstation 12. I have around 9.7GB of RAM allocated to the VM. When I run free, this is my output:
tex@ubuntu:~/neuraltalk2$ th eval.lua -model ~/Desktop/model_id1-501-1448236541.t7_cpu.t7 -image_folder ~/catkin_ws/video_images/Best\ Melodic/ -num_images -1 -gpuid -1
DataLoaderRaw loading images from folder: /home/tex/catkin_ws/video_images/Best Melodic/
listing all images in directory /home/tex/catkin_ws/video_images/Best Melodic/
Its just stuck there. Been stuck there for maybe 30 minutes. There are only 45 jpeg files.
I have tried changin the number of images, deleting images, making only one image available.... I dont know what to do. Its JPEG, do I don't think there should be a problem because its supported, right?
IMPORTANT: I changed the DataLoaderRaw.lua file to this:

Is there an obvious error somewhere? I changed the function DataLoaderRaw:__init(opt) in this script to sort the files loaded by the DataLoader before appending them to self.files(line 52). Without this functionality, captions are generated for images in a random order and the progression of a scene is impossible to determine.
