Cannot run on Google Colab

Describe the problem

Trying to work on a dataset that has 40+ features and more than 600,000+ data points, and wanted to work with modin for an efficient system to load data set, however, I work with my team on a shared Google Colab Jupyter Notebook, and am unable to install the same.
I tried simple pip install modin, but that didn’t work, so I tried, pip install modin[dask], that as well threw an error!

Source code / logs

ModuleNotFoundError Traceback (most recent call last) /usr/local/lib/python3.6/dist-packages/modin/init.py in get_execution_engine() 27 try: 28 import ray 29

ModuleNotFoundError: No module named ‘ray’

During handling of the above exception, another exception occurred:

@devin-petersohn, @manesioz

I got it working with the solution @manesioz provided, however, it required me to make a multiple restart of my runtime, which is absolutely weird.

When I installed it initially, and restarted the runtime it still did not recognize the package, however after repeating the process again, I did a multiple restart which seemed to solve my problem.

I don’t know why I had to that though.

Thanks @pratikwatwani, that is strange. I am glad it was sorted out, thanks for posting the resolution!
