How to connect to Firebird?

Question

Python

How to connect to the base? About a year ago I connected in exactly the same way and everything worked, but now I don’t want to in another project.
Here is the code:

import fdb

con = fdb.connect(dsn='127.0.0.1:D:/Dev/Python/Electra-AC_face-recognition/train.fdb', user='SYSDBA',
                      password='masterkey')
cur = con.cursor()
cur.execute("select * from USERS")
result= cur.fetchall()
print(result)

But he breaks off on the first line. Here is the error:

Traceback (most recent call last):
  File "D:/Dev/Python/Electra-AC_face-recognition/training_model.py", line 147, in <module>
    firebird()
  File "D:/Dev/Python/Electra-AC_face-recognition/training_model.py", line 130, in firebird
    con = fdb.connect(dsn='127.0.0.1:D:/Dev/Python/Electra-AC_face-recognition/train.fdb', user='SYSDBA',

Answer 1

Python version - 3.8.9, Firebird - 2.5.9
I found the solution! The matter is that Python was x64, and Firebird x32. Reinstalling Firebird helped :)
