Hi @Kiran Chalasani​ ,

According to the docs DBR 7.3 LTS comes with Numpy 1.18.1 https://docs.databricks.com/release-notes/runtime/7.3.html and DBR 9.1 LTS comes with Numpy 1.19.2 https://docs.databricks.com/release-notes/runtime/9.1.html

If you need to install a newer version, then you can create a init script or install the version you need. For more details on how to do it, please check the examples in the docs https://docs.databricks.com/libraries/index.html
