error message of No module named 'tensorflow' in GCP AI Platform Notebook
You have probably selected an instance type that doesn't have tensorflow pre-installed. 
After you install a Python dependency you will have to restart the Python Kernel for updates to take effect by clicking on Kernel->Restart Kernel....
I launched a notebook with GCP AI Platform. Then, I tried to install tensorflow by:
import tensorflow as tf
There is an error message of 

No module named 'tensorflow' 

I tried to install it by:
!pip install -U --user tensorflow==1.14.0
But the same error message appeared. As it is a GCP platform, I wonder why I need to install tensorflow. During Coursera training, I can import tensorflow directly without installation. I wonder if I missed anything.
Grateful if you can help.
Thank you
