FROM langflowai/langflow:1.0-alpha
CMD ["python", "-m", "langflow", "run", "--host", "0.0.0.0", "--port", "7860"]
To resolve the issue with your application failing to start using Docker Compose with the alpha release of Langflow due to a TypeError related to Pydantic v1 for Python 3.12.4+, you need to ensure that the correct version of Pydantic is being used. Pydantic v1 is not compatible with Python 3.12.4+, so you should upgrade to Pydantic v2.
Here is how you can modify your Dockerfile to install Pydantic v2:
- Open the
Dockerfilefile. - Add a line to install Pydantic v2.
For example, your Dockerfile might look like this:
FROM langflowai/langflow:1.0-alpha
# Install Pydantic v2
RUN pip install pydantic==2.0.0
CMD ["python", "-m", "langflow", "run", "--host", "0.0.0.0", "--port", "7860"]Make sure to replace 2.0.0 with the latest version of Pydantic v2 if necessary.
After making these changes, rebuild your Docker image and restart your Docker Compose setup:
docker-compose down
docker-compose build
docker-compose upAdditionally, ensure that your pyproject.toml file specifies a compatible Python version. According to the Langflow pyproject.toml, the supported Python versions are >=3.10,<3.12. If you are using Python 3.12.4+, you may need to downgrade to a compatible version:
[tool.poetry.dependencies]
python = ">=3.10,<3.12"This should resolve the TypeError related to Pydantic v1 for Python 3.12.4+. Note that the pyproject.toml file for Langflow already specifies Pydantic v2.5.0, so ensure your dependencies are up to date:
[tool.poetry.dependencies]
pydantic = "^2.5.0"This should help you get past the error and successfully start your application [1][2][3].
