* research/attention_ocr: Minor changes to make it compatible with python 3.

* research/attention_ocr: Script to create a smaller test file.

Some python files under models/research, it is wrong to use "Rather then" instead of "Rather than" in  comments.

Use temp variable for predictions.

Before the fix the demo_inference.py used batch_norm and it did the
normalization of input image implicitly. If at inference time the
batch_norm was disabled the inference produced incorrect results.
This fix does the proper input image normalization and disables the batch_norm
at inference time.

1. Update README.md
2. argmax, use axis instead of deminsion
3. use tf.profiler.profile instead of model_analyzer.print_model_analysis
