oasislmf.pytools.utils.redirect_logging(exec_name, log_dir='./log', log_level=logging.WARNING)

Decorator that redirects logging output to a file.

Apply to the main run function of a python exec from the pytools directory. Only errors will be send to STDERR, all other logging is stored in a file named:

“<log_dir>/<exec_name>_<PID>.log”

Each log file is timestamped with start / finish times

❯ cat log/fmpy_112820.log 2023-03-01 13:48:31,286 - oasislmf - INFO - starting process 2023-03-01 13:48:36,476 - oasislmf - INFO - finishing process

Args:

exec_name (str): The name of the script or function being executed. This will be used as part of the log file name. log_dir (str, optional): The path to the directory where log files will be stored. Defaults to ‘./log’. log_level (int or str, optional): The logging level to use. Can be an integer or a string. Defaults to logging.INFO.

Returns:

function: The decorated function.

Example:

@redirect_logging(exec_name=’my_script’, log_dir=’./logs’, log_level=logging.DEBUG) def my_run_function():

# code here

oasislmf.pytools.utils.assert_allclose(x, y, rtol=1e-10, atol=1e-08, x_name='x', y_name='y')

Drop in replacement for numpy.testing.assert_allclose that also shows the nonmatching elements in a nice human-readable format.

Args:

x (np.array or scalar): first input to compare. y (np.array or scalar): second input to compare. rtol (float, optional): relative tolreance. Defaults to 1e-10. atol (float, optional): absolute tolerance. Defaults to 1e-8. x_name (str, optional): header to print for x if x and y do not match. Defaults to “x”. y_name (str, optional): header to print for y if x and y do not match. Defaults to “y”.

Raises:

AssertionError: if x and y shapes do not match. AssertionError: if x and y data do not match.
