Abstract base classes have incorrectly decorated methods

[smokestacklightnin]

If the bug is related to a specific library below, please raise an issue in the
respective repo directly: TFX

System information

• Have I specified the code to reproduce the issue (Yes, No): Yes
• Environment in which the code is executed (e.g., Local(Linux/MacOS/Windows),
  Interactive Notebook, Google Cloud, etc): All
• TensorFlow version: All
• TFX Version: 1.15.1
• Python version: All
• Python dependencies (from pip freeze output): All

Describe the current behavior

There are currently violations of Ruff rules B024 and B027, which have to do with incorrectly decorated class methods/properties. Fixing them currently causes errors (See #6942), so that issue should be dealt with before this one.

Describe the expected behavior

See python docs for the correct way to make methods and properties abstract.

Other info / logs

The code violating B024 and B027 is listed below:

Hi @smokestacklightnin,
Thank you for reporting. I'll take a look and provide an update here.

QQ. How could you see those Ruff errors?

QQ. How could you see those Ruff errors?

Using the ruff check command

[lego0901]

Hmm.. My ruff check shows different errors like F401, and there is no B024 and B027. Could you let me know how to reproduce your output?

[smokestacklightnin]

This on example of a command I used on the master branch:

$ ruff check tfx --exclude tfx/examples/airflow_workshop/taxi/notebooks/*.ipynb --select B

from the root project directory

[lego0901]

Great! Now I see the message. Thanks a lot!
