scikit-learn version issue

[Ezzaldin97]

Description: There is an issue with OneHotEncoder, as it isn't accepting argument 'sparse'

explanation: recent versions of OneHotEncoder Object changed the 'sparse' argument to 'sparse_output', so this error is because of the issue in the dependencies version.

solution: this can be solved either by limiting the versions of the dependencies or handling the code to match the recent versions.

issue:
