Unable to Import and install Dataprovider in Pycharm

In Module16, there is an example to import dataprovider. To repeat a test case on parameterizing with different set of data.

But, I'm unable to import Dataprovider in Pycharm.

import dataprovider
import pytest
class Test_A():

    @pytest.mark.parametrize("username","password",[("user1","pass1"),("user2","pass2"),("user3","pass3")])
    def test_A(self):
        print("I'm in test A")
        print(dataprovider.data("username","password"))
