I'm trying to train a model using the models here https://github.com/tensorflow/models/blob/master/research/deeplab/g3doc/model_zoo.md What does the Eval scales here means? I thought it may be scale for the image size but why it is three dimension in some cases? Thank you!

eval_scales is a list of scales which are used to resize the image in the evaluation process. The default value is [1.0] --> The image is not resized and no multi-scale test is performed. If you provide a list with multiple scale values (for instance: [0.5, 1.0]) the network is evaluated by performing multiple inferences using varying image resolutions.

By using eval_scales, you can't specify the scaling of a certain image dimension but each scaling factor is applied on both spatial dimensions of the input image.
