Hello,

I totally removed and reinstalled langflow, to update to new 1.1.0 version, while doing that i got very bad error...

while running:
python3 -m langflow run --env-file ./.env --no-open-browser --auto-saving --host localhost

got error:

> RuntimeError: There's a mismatch between the models and the database.

To resolve the RuntimeError related to a mismatch between models and the database when reinstalling Langflow version 1.0.10, you can use the run_migrations method with the fix parameter set to True. This will attempt to downgrade and upgrade the database schema until the mismatch is resolved.

Here's how you can do it:

database_service = DatabaseService(settings_service)
database_service.run_migrations(fix=True)

This code snippet initializes the DatabaseService and runs the migrations with the fix option enabled, which will handle any mismatches by downgrading and upgrading the database schema until successful ^[1].

Additionally, there is a similar unsolved discussion about a large list of errors after running langflow migration --fix, which might be related to your issue. You can find more details in this discussion ^[2].

To continue talking to Dosu, mention @dosu.

did not work

~$ langflow migration --fix

This will delete all data necessary to fix migrations. Are you sure you want to continue? [y/N]: y

seems like removing db files from ~/.local/lib/python3.10/site-packages/langflow and running again langflow migration --fix worked out... now langflow starts, but with errors

Hi, I totally removed older version all with dependencies and db files thanks a.

italojohnny · 2024-11-14T15:55:59Z

Right! I'm trying to reproduce the issue!

severfire · 2024-11-14T17:09:13Z

Thank you for your help! I also wonder if that may be server related issue like with rights or something related to python itself what information would you need to have?

I think I fixed it. It has something to do with the psycopg2 dependency. The current version uses sqlalchemy and the prior versions uses psycopg directly.
"psycopg2-binary>=2.9.6",
"psycopg>=3.1.9",
#"sqlalchemy[aiosqlite,postgresql_psycopgbinary]>=2.0.36",

Also I made some changes to the service.py to always define the driver for postgres. I will need to double check what was doing the trick but then I can probably give an update.

@KevinMichaelSchindler awesome! @italojohnny If that would be the issue, I wonder if the hotfix for langflow could be released? I am also using sqlite version

@KevinMichaelSchindler awesome! @italojohnny If that would be the issue, I wonder if the hotfix for langflow could be released? I am also using sqlite version

The previous langflow version worked without the sqlalchemy dependency but probably there is a reason for adding it so it might be that some specific component or scenario breaks when reverting the dependencies. The default docker image uses postgres so I haven't tested the sqlite version. The tests definitely break for the sqlite stuff so more tinkering needs to be done to get the sqlite stuff to work. I assume the langflow team will bring out a proper fix soon but I thought I'll share this for the folks who are currently struggling with it.

P.S. I confirmed that when I change just the dependency to:
"psycopg2-binary>=2.9.6",
"psycopg>=3.1.9",
#"sqlalchemy[aiosqlite,postgresql_psycopgbinary]>=2.0.36",

It seems to work for the default docker yml, so no changes to service.py are required it seems.

KevinMichaelSchindler · 2024-11-15T14:08:12Z

I tried to add the aiosqlite manually:
"aiosqlite>=0.19.0",

But there are still unresolved errors:
FAILED src/backend/tests/unit/api/v1/test_users.py::test_add_user - RuntimeError: There's a mismatch between the models and the database.

Results (312.75s (0:05:12)):

make[1]: *** [Makefile:133: unit_tests] Error 1
make[1]: Leaving directory '/mnt/b/Dokumente/langflow2/langflow'
make: *** [Makefile:164: tests] Error 2

So currently the dependency update fixes the postgres issues but not the sqlite stuff as it seems.

severfire · 2024-11-15T14:17:10Z

@KevinMichaelSchindler that was the error i was getting at the beginning, mismatch between the models and the database... after next reinstall i got #4593 (comment)

KevinMichaelSchindler · 2024-11-15T14:32:30Z

You are using sqlite in your .env right? (python3 -m langflow run --env-file ./.env --no-open-browser --auto-saving --host localhost)

I just tested it for the "make init" locally and the docker-compose.yml in the docker-example. These use postgres out of the box but the docker image was showing the same error regarding sqlalchemy, so that is what I fixed.

As said if you are using sqlite there might be some additional fixing required, I am sorry :(

severfire · 2024-11-17T22:30:31Z

@KevinMichaelSchindler Yes, I am. I used pip installation. I am not using docker installation here.
Hmm... I wonder how many people have similar problem... its not small thing I guess...
@italojohnny were you able to replicate the issue?

severfire · 2024-11-18T08:02:51Z

I found the issue is with dependencies, especially Pydantic, used AI to help me a bit...

Final Codebase Context
Based on the provided codebase, Langflow uses both Pydantic v1 and v2. This can be seen in several places:
In the dependencies from pyproject.toml:
Shows "pydantic>=2.7.0" and "pydantic-settings>=2.2.0" as dependencies.

However, there are also explicit imports from pydantic.v1 in several files, for example in the flow model:
This dual usage pattern suggests that Langflow is in a transition period between Pydantic v1 and v2, likely maintaining compatibility with both versions. This is a common pattern for libraries that are migrating from Pydantic v1 to v2 while maintaining backward compatibility.

The main version requirement is Pydantic 2.x (>=2.7.0), but the codebase still uses some v1 imports for specific functionality that might not have been migrated yet or requires v1 compatibility.

Hello @severfire, @KevinMichaelSchindler and @greenmotion ,

First of all, I want to express our deep gratitude for everyone’s help in making Langflow a better tool. Your support means a lot to us!

Secondly, I apologize for the delay in responding. This particular issue has been quite challenging to reproduce. In addition to myself, others are also working to address it.

The tracebacks point to a migration issue, but the exact cause remains unclear. There is a possibility that fix #4599 resolved the problem. However, since we haven’t been able to reproduce the issue consistently, we cannot guarantee this with 100% certainty yet.

For this reason, I would recommend, as an alternative, trying out the nightly version, which already includes this fix along with others. This might serve as a temporary solution until we can confirm the fix and proceed with the next official release.

Thank you for your patience and understanding

severfire · 2024-11-18T22:26:04Z

@italojohnny I have feeling it is python dependency issue. (I was playing with reinstalling different versions of Pydantic, staying with latest version, and also with pip install grpcio==1.59.0 grpcio-tools==1.59.0) Anyhow today my morning - like 12h ago I was able to run langflow, but it did not load .env config, I had to use exports. next week or later this week I will check your fixes, as right now my installation seems stable (with workarounds), and I have to do different tasks) thank you for all your help!

greenmotion · 2024-11-19T14:56:17Z

@italojohnny: I'd be more than happy to test your nightly build, but I must admit I'm relatively new to Python and have been running Langflow in a venv and not a docker container. How would I update my langflow instance to a nightly build version?
