Why is kernel dying in Jupyter?
Maybe your dataset is too large or you are using some parameters for the model which takes huge computer power…that is why it is crashing…would suggest using COLAB or KAGGLE for doing memory intensive operations… I had the same problem with a large dataset running Jupyter Lab on my computer.
How do you fix a dead kernel in Jupyter Notebook?
