can you share your code please?
client = pyorient.OrientDB('localhost', 2424) session_id = client.connect('user', 'password')
pyorient.exceptions.PyOrientWrongProtocolVersionException: Protocol version 37 is not supported yet by this client.
pyorient 1.5.5 orientdb 3.0.0
Same problem here. pyorient 1.5.5 orientdb 3.0.2
Same issue.

i am using 3.0.2 and pyorient 1.5.5
Same issue using the current Docker image.
I just wanted to try OrientDB and am not sure what a patch would encompass. No matter how complicated that may be, the Repository README states:
Pyorient works with orientdb version 1.7 and later.
As a first measure: Could someone adjust that line, pointing to the last working OrientDB (2.x) version?
For Docker it works with orientdb:2.2.35
.
@dersmon good point, since at moment i have not enough time to advance the version at least until august i think, this is the best option.
I changed SUPPORTED_PROTOCOL
in constants.py
from 36
to 37
and it connects... now, is there going to be a bunch of buggy behavior?...Not the kind of thing for a production environment, but it got me back to my project.
Hi @softwareCobbler ,
not tried, not tested and I don't know which issues there could be. Could be useful to know which problems you find as a good starting point to short cut the driver improvement.
@mogui: Is there any plan to update pyorient to support version 3.x reliably?
I have looked into this a bit. This client throws an error if the OrientDB server is of a more recent version than the client. The official Java client has slightly different behaviour, it just raises a warning that you will not be able to use the full features of the newer version.
It looks like both the python and Java clients attempt to connect to the server using the clients preferred protocol version, and expect the server to handle it.
I have tweaked the connection version checking in the python client to mirror that in the java client, and I'm going to give it a shot and see how it goes. (So far I have tried connecting to a V3.0.5 OrientDB and querying a graph successfully).
Note: links are to the relevant sections of code.
@softwareCobbler I tried your approach and got the following
pyorient.exceptions.PyOrientDatabaseException: com.orientechnologies.orient.core.exception.OConfigurationException - You can use connect as first operation only for protocol < 37 please use handshake for protocol >= 37
HI Tariq, We’ve been very busy with our everyday jobs, hopefully they will calm down soon, and we’re look into that soon, We’ve got some ideas on how to maintain compatibility, hang on :)

Sorry to ping you directly, but any idea about the status of this issue?

Hi Mogui! Any updates on this yet? Our development team really looks forward to testing pyorient with our OrientDB-server, version 3.0.7
Yours sincerely /Kjell
Hi Mogui,
Do you guys have any estimations about fixing it? Or any proper python temporary solution to use mean while?
Thanks!!
@mogui
Thanks for the reply. I ended up deleting my comment because I found that commenting out the error message (or invoking warning.warn()
instead of raising in my case) will work.
@klkludde @montequie: What I suggested above is not particularly elegant, but it should work as a stopgap measure.
@TariqAHassan
Can you repost your suggestion? can't find it here
Hi @montequie
See here.
@TariqAHassan Thanks a lot! It worked.

Let me add my encouragement to update to 3.x as well.. :)
I'm a new user to OrientDB. I have a project that I'm working on and I'm nervous to build and then have to migrate to 3.x later on.
Is there any fix for pyorient with Orientdb 3.0 I got error like Protocol version 37 is not supported yet by this client

Is there any plan to fix this?

If someone needs to use odb3 with python, just use master branch instead of the last release.
pip install git+https://github.com/orientechnologies/pyorient
If you just start a new project, I recommend using a more up-to-date dbsm (redisgraph or other).
I'm sorry, but... what the hell is going on here?
Try out orientdb -> use pyorient -> latest, and right off the bat I run into a non-starter because of a constant that hasn't been updated in almost 2 years now? (Along with other changes that haven't been implemented along with that constant bump)
The issue is back. You can fix this by overriding the connect method in OrientSocket:
from pyorient import OrientSocket
class PySocket(OrientSocket):
def __init__(self, host, port, protocol=36, timeout=300):
"""
Override OrientSocket protocol version number
to fix PyOrientWrongProtocolVersionException where:
'Protocol version 37 is not supported yet by this client.'
"""
super(PySocket, self).__init__(host, port)
self.protocol = protocol
self.host = host
self.port = port
self.timeout = timeout
def connect(self):
"""
Override OrientSocket connect method
to fix PyOrientWrongProtocolVersionException where:
'Protocol version 37 is not supported yet by this client.'
"""
self._socket.settimeout(self.timeout)
self._socket.connect( (self.host, self.port) )
_value = self._socket.recv(2)
if len(_value) != 2:
self._socket.close()
self.connected = True
then
HOST = "localhost"
PORT = 2424
DATABASE_NAME = "<dbname>"
DB_USER = "admin"
DB_PWD = "admin"
socket = PySocket(HOST, PORT)
socket.connect()
client = OrientDB(socket)
client.db_open(DATABASE_NAME, DB_USER, DB_PWD)
OrientTechnologies removed (in their fork) the if statement causing the error :) https://github.com/orientechnologies/pyorient/commit/5bbe000acb0e65d49a3f85bd0ecf9d40ae155467 (long time ago it seems)
Orient 3+ documentation page links their own fork as the repo to be used (just passing on the message) Probably because this current bug has not been fixed. Check this link under Developers/Python (change of repo for 3+) http://orientdb.com/docs/3.0.x/
Tested on: Orientdb 3.0.30 Pyorient 1.5.5 (not working as per ticket) then upgraded to version below.
If you want to try it below, it works, i checked. Just change your python package location from pypi package of this repo to git-based package of OrientTechnologies repo.
In your requirements.txt find line
pyorient=1.5.5
and change to
-e git+https://github.com/orientechnologies/pyorient.git@master#egg=pyorient
then
pip uninstall pyorient && pip install -r requirements.txt
Now the connection as plain as below is working without the error. And be sure to check the first link with the funny fix to have a laugh.
import pyorient
from pyorient.ogm import Graph, Config
graph = Graph(Config.from_url('plocal://127.0.0.1:2424/mydb', 'root', 'supersecret'))
Hi @rrmerugu. Install pyorient from source as given here PyOrient Installation after this you no longer will face this issue.
Or use pyorient=1.5.1 with this version this work fine.
@styk-tv's solution fixes the connection problem (thank you for that), but still there are several more issues that's the driver itself.
token = client.get_session_token()
client.set_session_token(token)
pyorient.exceptions.PyOrientBadMethodCallException: Unable to find command 'DbQueryMessage'
Granted these are different bugs, I need to warn that you will run into more issues even if you get around this specific issue on this bug.
Getting same issue in 2024. No solutions, huh?
When i try to establish a connection to the db from pyorient, the below error is showing up. im using pyorient==1.5.5, is it possible its not compatible with orientdb 3.0.0. Any plans to support pyorient for orientdb 3.0.0 version soon ?
PS: This is the version of the orientdb i'm using https://orientdb.com/download.php?file=orientdb-community-gremlin-3.0.0.tar.gz
