Issue when generating config file while using build_config

[RajARROW]

While running build_config command with path to --trait-dir and if once of the layer folder contains 3 images. The auto generated file contains weights as 33, 33 and 33. The generator will give error as weight adds to 99 not 100. So is in many other cases like when its 6 with 16.
