Why does my google colab session keep crashing?
I would first suggest closing your browser and restarting the notebook. Look at the run time logs and check to see if cuda is mentioned anywhere. If not then do a factory runtime reset and run the notebook. Check your logs again and you should find cuda somewhere there.
I am using google colab on a dataset with 4 million rows and 29 columns. When I run the statement sns.heatmap(dataset.isnull()) it runs for some time but after a while the session crashes and the instance restarts. It has been happening a lot and I till now haven't really seen an output. What can be the possible reason ? Is the data/calculation too much ? What can I do ?
