@rajdeepdas2000 hey there, thanks a lot for wanting to contribute. You can join the Activeloop community slack (slack.activeloop.ai) to ask questions. :)

I installed deeplake on Ubuntu 22.04.1 LTS. Then I run the above mentioned lines of code on jupyter notebook. The mnist-trian dataset is displayed successfully by running the ds.visualize() command. I suggest you to kindly re run/install all the required things (jupyter, deeplake, pip, etc) and re- running this code. Hopefully it will execute without errors.
