Answer 1

I've met same problem and fixed it changing connection string like below. Write

'DRIVER={ODBC Driver 13 for SQL Server}'

instead of

'DRIVER={SQL Server}'

Answer 2

Below connection string is working

import pandas as pd
import pyodbc as odbc

sql_conn = odbc.connect('DRIVER={ODBC Driver 13 for SQL Server};SERVER=SERVER_NAME;DATABASE=DATABASE_NAME;UID=USERNAME;PWD=PASSWORD;')

query = "SELECT * FROM admin.TABLE_NAME"
df = pd.read_sql(query, sql_conn)
df.head()

Answer 3

Have you installed any product of SQL in your system machine ? You can download and install "ODBC Driver 13(or any version) for SQL Server" and try to run if you havent alerady done.
