Code Review

This pull request removes a redundant line in base_class.py that incorrectly set n_nodes to 1, and adds a corresponding unit test to verify multi-node MPI command warnings. The reviewer pointed out a potential ValueError when converting n_nodes to an integer if it is not a valid integer string, suggesting a robust try-except block to handle this case.

Code Review

This pull request fixes a bug in parsing the n_nodes variable where it was previously always evaluated to 1 due to a buggy ternary operator. It also adds a corresponding unit test to verify warnings when running multi-node experiments without an MPI command. The reviewer suggests making the n_nodes parsing more robust by handling float strings, unexpanded placeholders, and potential parsing exceptions gracefully.
