[BUG] : undefined symbol: `EVP_PKEY_base_id` (in `mgclient.cpython-39-x86_64-linux-gnu.so`) about gqlalchemy HOT 19 OPEN

Can you try installing gqlalchemy without conda, to verify the assumption?

from gqlalchemy.

Hi @Tim-K-DFW, can you try pip install GQLAlchemy==1.4.1 until we detect if this is a bug related to latest release?
Btw as far as I can see, you're using Python 3.9?

from gqlalchemy.

Hi Katarina, thank you for the quick response!

• Same result with 1.4.1
• Yes, python 3.9.16.

from gqlalchemy.

Did you experience any issues when installing with pip?
Also when you installed can you confirm installation is okay by running pip show gqlalchemy and provide output?
P.S. I see you are using Linux OS but is this a virtual machine or not? Wondering about your device architecture, is it ARM or AMD?

from gqlalchemy.

1. The only issue first time was pip complaining of cmake missing, so I installed that, and then gqlalchemy installed with no problems.

2. pip show gqlalchemy gives:

Python 3.9.16
(memgraph) t@DESKTOP-KHJBONB:~/ro5_wsl/memgraph$ pip show gqlalchemy
Name: gqlalchemy
Version: 1.4.1
Summary: GQLAlchemy is a library developed to assist with writing and running queries in Memgraph.

3. This is WSL2 on a Windows 10 machine, standard Intel CPU (AMD architecture as I understand).

from gqlalchemy.

Can you remove that installation, install all necessary prerequisites for GQLAlchemy (that is, pymgclient) and then try reinstalling it?

from gqlalchemy.

I did:

• new conda env with python 3.9.16
• sudo apt install python3-dev cmake make gcc g++ libssl-dev (from your link)
• pip3 install --user pymgclient (from your link)
• pip install GQLAlchemy==1.4.1

Same result:

I think that might be related to the mismatch of the OpenSSL version. Can you tell me which version you have?

from gqlalchemy.

from gqlalchemy.

Are you sure that conda env uses that OpenSSL by default? This reminds me of the closed issue on the pymgclient repository.

from gqlalchemy.

Do you happen to know how I can check this?

from gqlalchemy.

(I mean, pip show openssl in this environment doesn't show any versions of openssl installed).

from gqlalchemy.

Can you try installing the pymgclient prerequisites in conda env with pip? The steps in conda env would be:

pip3 install python3-dev cmake make gcc g++ libssl-dev
pip3 install pymgclient
pip3 install gqlalchemy==1.4.1

from gqlalchemy.

ERROR: Invalid requirement: 'g++' 😬 I googled a few solution options but not sure what exactly you had in mind.

from gqlalchemy.

My mistake on pip side. But the issue you're facing should be related to conda. I will do more research on what happened tomorrow and get back to you. Meanwhile, I recommend you read the issue I provided that might help and see why OpenSSL is not visible in your conda env.

from gqlalchemy.

YES! In vanilla python, it's importing with no issues. This has to be some Conda stuff. Thank you so much!

from gqlalchemy.

No problem, I'm glad to help and happy it's working for you now! I will leave this issue open to resolve conda issues 😄

from gqlalchemy.

Investigated the issue, you are probably having locally old version of pymgclient. Clean pymgclient from global path (pip uninstall pymgclient gqlalchemy), activate your conda environmen and install ONLY gqlalchemy (pip install gqlalchemy). You should see that pymgclient 1.3.1 is being built while installing gqlalchemy. No need to install pymgclient before gqlalchemy, we have wrong instructions in README, we will fix it.

from gqlalchemy.

@Tim-K-DFW let us know if you decide to try out Conda env again and verify if what @as51340 provided fixes the issue 😄 Thanks!
