Tapas classifier experiment doesn't disable v2 tensorflow behaviour which leads to AttributeError

[Maxvgrad]

When running tapas_classifier_experiment.py leads to the error AttributeError: 'int' object has no attribute 'value'.

The issue happens because the file doesn't disable_v2_behavior

tapas_classifier_experiment

``` python tapas/experiments/tapas_classifier_experiment.py \ --use_tpu=False \ ... --eval_interactions_file="${BASE_DIR}/${FT_RESULTS_DIR}/interactions/random-split-1-dev.tfrecord" \ --predict_interactions_file="${BASE_DIR}/${FT_RESULTS_DIR}/interactions/test.tfrecord" \ --do_train ```
