[PythonImageDeveloper]

Hi ,
Q1) Anchor_Boxes_Generator file generate 10 values of anchors , i have question about these values , as we have 5 anchors and this generator generate 10 values, more likely a first two of 10 values related to first anchor box , right ? if so , what are means of these two values ? W , H for first anchors for aspect ratio and scale for that anchor?
Q2) Is it possible to fine-tuning this with one GTX 1080 (8G)?
