"ImportError: DLL load failed while importing _sqlite3: The specified module could not be found."

Change the import _sqlite3 to import sqlalchemy. If that doesn't work try to do import sqlite plain and simple. Have a nice day.

copy sqlite.dll

Try copying the sqlite3.dll from the

C:\Users\YOURUSER\anaconda3\Library\bin

folder to

C:\Users\YOURUSER\Anaconda3\DLLs
