What data are you going to read? How did you create these data?
I think this is the key part:

W c:\tf_jenkins\home\workspace\release-win\device\gpu\os\windows\tensorflow\core\framework\op_kernel.cc:975] Invalid argument: Input to DecodeRaw has length 154587 that is not a multiple of 4, the size of float
