SQLite driver available but don't load- QSqlDatabase

[Rhotaber]

Hi,

I'm coding in PyQt5 ( version 5.9.2 ) in Ubuntu (using anaconda/spyder environment) and I'm trying to access a database by QSqlDatabase but

import sys
import sqlite3
from PyQt5.QtWidgets import QApplication, QWidget, QTableView, QHBoxLayout
from PyQt5.QtSql import QSqlDatabase
 
 
if __name__ == "__main__" :
    app = QApplication(sys.argv)
    t = QWidget()
    print(list(map(str, QSqlDatabase.drivers())))
    dbname = "test.db"
    db = QSqlDatabase()
    db.addDatabase("QSQLITE")
    db.setDatabaseName("test.db")
    if(db.open()):
        print("Opened!")
        db.close()
    else:
        print(db.lastError().databaseText())
        print(list(map(str, db.drivers())))
 
 
 
    t.show()
    sys.exit(app.exec_())

import sys
import sqlite3
from PyQt5.QtWidgets import QApplication, QWidget, QTableView, QHBoxLayout
from PyQt5.QtSql import QSqlDatabase


if __name__ == "__main__" :
    app = QApplication(sys.argv)
    t = QWidget()
    print(list(map(str, QSqlDatabase.drivers())))
    dbname = "test.db"
    db = QSqlDatabase()
    db.addDatabase("QSQLITE")
    db.setDatabaseName("test.db")
    if(db.open()):
        print("Opened!")
        db.close()
    else:
        print(db.lastError().databaseText())
        print(list(map(str, db.drivers())))
        
    
    
    t.show()
    sys.exit(app.exec_())

To copy to clipboard, switch view to plain text mode 

gives me
Driver not loaded
['QSQLITE']

When I run ldd libqsqlite.r in the folder sqldrivers inside the folder where I have installed PyQt5 it gives me :
