I try to install tensorflow federated.
pip install --quiet --upgrade tensorflow_federated_nightly
but when I want to import tensorflow federated, I get this warning and after that google colab notebook is restarted.

Also, I try install tensorflow federated as this way:
pip install --quiet --upgrade tensorflow_federated
but get error when import tensorflow federated
TypeError: 'type' object is not subscriptable
how do I fix it?
