fit_generator throws error on validation data being float data type

I'm trying to run CUHK03 Person Re-ID script.
Error text reads as follows:

I am using Jupyter Notebook in Anaconda on Windows 10(x86).
Keras version 2.1.3
Python version 3.6.3
Tensorflow backend (1.4.0)

I am not gonna give targeted solution but I guess keras version may be giving you some of the problems .. my bugs were different from your but i was having keras 2.1 > ... I downgrade it to 2.0.0 and issues with keras version were solved... Also , I see your Tensorflow version is also different version to the one on which the model was developed ... you may consider checking the development environment the contributor tested the code on as given here https://github.com/Ning-Ding/Implementation-CVPR2015-CNN-for-ReID

@adityak6798 you need to use the keras version 2.0.0
