cannot import name 'resolve_types' from 'attr'

[sephethus]

Apache Airflow version: 1.10.12

Kubernetes version (if you are using kubernetes) (use kubectl version):

Environment:

• Cloud provider or hardware configuration: Local PC
• OS (e.g. from /etc/os-release): Ubuntu 20.04
• Kernel (e.g. uname -a): 5.4.0-56-generic Adding ftp hook #62-Ubuntu SMP
• Install tools: docker-compose using https://github.com/puckel/docker-airflow
• Others:

What happened:

Webserver will not start due to airflow error: ImportError: cannot import name 'resolve_types' from 'attr' (/usr/local/lib/python3.7/site-packages/attr/init.py)

What you expected to happen:

Webserver start to test dags locally

How to reproduce it:

Use the docker-compose container above https://github.com/puckel/docker-airflow.git
Ubuntu 20.04
Run docker-compose up

Error occurs every single time.

Things already tried:

Modified dockerfile to include constraints for Python 3.7 container: --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-1.10.12/constraints-3.7.txt"

Added cattrs==1.0.0

Downgraded pip==20.2.4

Added attrs

None of the above suggestions are working. Anyone able to reproduce this and help solve?

Also I would suggest to consider using community supported docker:

docker pull apache/airflow:1.10.12-python3.6
