Dear mpatacchiola,

Thanks for your help!

https://github.com/mpatacchiola/deepgaze/blob/master/examples/ex_dnn_head_pose_estimation_training/ex_aflw_parser.py

In the above file:

#Separating the label from the dataset dataset = data[:,0:4096] label = data[:,4096:4099]

I think length of the image in 1D should be 64*64 = 4096? It's 1600 in the current commit and I got error when I try to run ex_dnn_head_pose_estimation_training.py :

Training set (19507, 1600) (19507, 3) Validation set (2438, 1600) (2438, 3) Test set (2439, 1600) (2439, 3) Starting Graph creation...

I changed the 1600 to 4096 and was able to proceed with ex_dnn_head_pose_estimation_training.py.

Also I did a brief search here, but didn't find such issue. Hope this is not a duplicate issue.

BR, JimmyYS

You should resize the face pictures to 64 * 64 at first
