Since the origin iris sample doesn't work with the new tensorflow(like 1.0, 0.12), so here is the fix version of that.
the sample page : https://www.tensorflow.org/get_started/tflearn
Just changed the old parameters with custom input pipe-lines, introduced on this page. https://www.tensorflow.org/get_started/input_fn
#Tips 1.please get the iris_predict.csv.
2.please make sure you delete the old tmp data, if you have any in the tmp folder.
3.this will be overfitting, if you try to train it twice in a row. (get [1,1] instead of [1,2])
