good hyperparams for large set

[flobotics]

hi,
i got 54500 images for trainA and 54500 for trainB, when i would set steps_per_epoch= to 54500, it would take on a K80/12GB around 54 hours for one epoch ? what is a good value for larger datasets ?

When i train the 54500 dataset with 100, or 500, or 5000 steps_per_epoch the strange thing happens that every input image gives exactly the same output image ? is it because i dont use 54500, all images for steps_per_epoch?

thanks
