Error while dumping out data from sqlite3

I have used sqlite3_connection.iterdump() method to dump the sqlite3 the database.

I have written a module in python that dumps out the sqlite3 tables. The module works fine if I run it locally in my machine.

And, After creating a python package of the module using pyinstaller, if I try to dump out the database it gives an error saying

"ImportError: No module named sqlite3.dump"

Any idea how I can solve this issue. Or is there any alternative to get the sqlite3 dump.

Thanks in advance!
