Typo fix

Update the runtime version in bash script

The bash script to submit training job for pets detection has runtime-version of 1.8. This will trigger `TypeError: non_max_suppression() got an unexpected keyword argument 'score_threshold'` on the Google Cloud since 1.8 and older does not support this keyword argument. Therefore, update this runtime version to 1.9, which is the most recent runtime version that is published on June 27, 2018. 

See 
https://github.com/tensorflow/models/issues/5056
https://cloud.google.com/ml-engine/docs/tensorflow/runtime-version-list

Updated model_lib to use min_score_threshold and max_num_boxes_to_visualize from the eval config.

Text classification tutorial clarification

Rename "num_examples" to "num_reviews" to be consistent with the "one-hot-encode" size description: "num_words * num_reviews".

* Fix convergence issues for MLPerf.

Thank you to @robieta for helping me find these issues, and for providng an algorithm for the `get_hit_rate_and_ndcg_mlperf` function.

This change causes every forked process to set a new seed, so that forked processes do not generate the same set of random numbers. This improves evaluation hit rates.

Additionally, it adds a flag, --ml_perf, that makes further changes so that the evaluation hit rate can match the MLPerf reference implementation.

I ran 4 times with --ml_perf and 4 times without. Without --ml_perf, the highest hit rates achieved by each run were 0.6278, 0.6287, 0.6289, and 0.6241. With --ml_perf, the highest hit rates were 0.6353, 0.6356, 0.6367, and 0.6353.

* fix lint error

* Fix failing test

* Address @robieta's feedback

Basic_Regression notebook: Python2 compatibility

Docs: Grammar fix

* perform a codecs check and remove unicode \ufeff if utf-8 is not present

* delint

Docs: fix iteration count

Update the epoc/iteration count noted to match the code.

Update plt.grid args to avoid deprecation message

This is done by using a higher Pickle protocol version, which the Python docs describe as being "slightly more efficient". This reduces the file write time at the beginning from 2 1/2 minutes to 5 seconds.

Modify flag name for the checkpoint path

* Deterministic dataset order fix

In order for the order of the files to be deterministic, in `tf.data.Dataset.list_files(..., shuffle)`, shuffle needs to be True, otherwise different iterator inits will yield different file orders

* removed unnecessary shuffle of filenames

* Removed the `_FILE_SHUFFLE_BUFFER` definition

Adding illustrative charts to basic classification tutorial

Nits in basic_regression.ipynb

* Remove trailing spaces
* Fix "dependant" spelling error
* Remove periods at the end of comments*
* Add spaces after commas*

\* For internal consistency and consistency with PEP8 examples
