if the given servers are ok, return true, else return false

option 1 control the connection release yourself
get session from the pool
session = connection_pool.get_session('root', 'nebula')
select space
session.execute('USE basketballplayer')
show tags
result = session.execute('SHOW TAGS') print(result)
release session
session.release()
option 2 with session_context, session will be released automatically
with connection_pool.session_context('root', 'nebula') as session: session.execute('USE basketballplayer') result = session.execute('SHOW TAGS') print(result)
close the pool
connection_pool.close()

Could you provide more details? You can try the following:
- Eliminate network issues first
- Make sure your remote port is open (the address seems to be deployed on the server)
- Check whether the nebula-python version corresponds to the nebula graph version. You can refer to here.
If the problem still exists after eliminating the above problems. You are welcome to provide more details, and feel free to ask.
