Greetings @ayush667787878 ,
The difference comes down to the type of compute you’re using. In your standard Databricks workspace, you’re running on Serverless — which doesn’t support installing additional libraries on the cluster.
In Community Edition (which is being retired at the end of the year and replaced by Databricks Free Edition), you’re working with classic Spark clusters, and those do allow package/library installs.
Hope this clears things up. Cheers,
Louis
