Fine-tuning a pretrained VGG-16 model

[Doc84]

I am trying to fine-tune the VGG-16 pretrained model using TF-Slim however, i am having trouble at the beginning (when attempting to preprocess the data i.e convert the images from tiff to jpeg and then to tfrecord format). Can you advise on the best method to use in order to finetune the model to suit these images?
Is there any way you could point me in the direction of a step by step guide on how to do this? Apologies as i am new to convnets and i am trying to figure out how to begin fine-tuning. Thanks in advance.

The image I/O of this framework is based on openslide, which is specific to whole-slide pathological images (http://openslide.org/). It does not support jpeg. If you want to process jpeg, just replace the function of "GetPatch()" by yourself-defined I/O.
