pip uninstall fails for databricks-dlt library

In Databricks, I had installed Databricks dlt library from here using the command pip install databricks-dlt. But now when I try to uninstall using the command pip uninstall databricks-dlt, I get the following error. How can I uninstall this library:

PipError: Command 'pip --disable-pip-version-check uninstall databricks-dlt' returned non-zero exit status 2.

By default Databricks disables all prompts for user input by pip package manager, so if there is a need of user input from user it fails automatically. This is defined by variable PIP_NO_INPUT. You can also check the value of this variable is set as 1 in Databricks

print(os.environ.get("PIP_NO_INPUT"))
#prints 1

As a solution you can run pip in non-interactive mode like below :

%pip uninstall -y databricks-dlt

I tested this in Databricks and it got uninstalled
