ModuleNotFoundError: No module named 'ray'

[Malathi15]

When I am trying to run the exercise01.ipynb I got the following error. Can anyone help me?
`from future import absolute_import
from future import division
from future import print_function

import ray
import time`

`---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)

----> 5 import ray
6 import time

ModuleNotFoundError: No module named 'ray'`

Thanks in advance.

Can you confirm that you have followed the installation steps described in the README file and that you've activated your conda environment before launching Jupyter notebook?

If you've done so, then ideally you should have the ray package installed and everything should run pretty smoothly.

Most likely you're having python dependency management issues.
Try running in the notebook found inside exercises/:

import sys
!{sys.executable} -m pip install -U ../ray

for other missing dependencies, use the same approach. I ran:

!{sys.executable} -m pip install modin
!{sys.executable} -m pip install tensorflow
!{sys.executable} -m pip install gym
!{sys.executable} -m pip install scipy
!{sys.executable} -m pip install opencv-python
!{sys.executable} -m pip install bokeh
!{sys.executable} -m pip install ipywidgets==6.0.0
!{sys.executable} -m pip install keras
