About the Poisson example

[eqfwrg424535]

Hello,

I am a Postdoc working in China University of Geoscience. I am interested in your work on the new algorithm for forward and inverse PDEs. And when I was testing the Poisson example, the following errors turned up. I have no idea how to fix them, could you please help me with that? Appreciate a lot.

ModuleNotFoundError Traceback (most recent call last)
D:\Anaconda3\lib\site-packages\odil\runtime.py in ()
36 try:
---> 37 import jax
38 backend_name = 'jax'

ModuleNotFoundError: No module named 'jax'

During handling of the above exception, another exception occurred:

You need to install jax or tensorflow. Do you have any of those?
