Cannot import run_classifier_with_tfhub

[sddoliver]

I'm running the tutorial without any changes as posted here, https://colab.research.google.com/github/tensorflow/tpu/blob/master/tools/colab/bert_finetuning_with_cloud_tpus.ipynb .
The line 'import run_classifier_with_tfhub' does not run, and gives a module not found error: 'ModuleNotFoundError: No module named 'run_classifier_with_tfhub''

Since I've run the earlier lines without error:
`import sys

!test -d bert_repo || git clone https://github.com/google-research/bert/blob/master bert_repo
if not 'bert_repo' in sys.path:
sys.path += ['bert_repo']`

I've checked help(bert_repo), and while it does list all of the other functions being imported in here, it does not list run_classifier_with_tfhub. As this issue was in #420 I tried to update bert_repo, pip install bert_repo --upgrade, and bert, pip install bert --upgrade, but both still give module not found.

On returning to the issue, import modeling failed before import run_classifier_with_tfhub was reached, and help(bert_repo) showed both modeling and run_classifier_with_tfhub to be in bert_repo. Restarted the colab kernel (which had been done multiple times previously), and everything now runs.
