class khiops.core.internals.common.CommandLineOptions(batch_mode=True, log_file_path='', task_file_path='', output_scenario_path='')¶

Bases: object

Khiops command line options

Attributes:

log_file_pathstr, default “”: Path of the log file for the Khiops process (command line option -e of the desktop app). If equal to “” then it writes no log file.
output_scenario_pathstr, default “”: Path of the output Khiops scenario file (command line option -o of the desktop app). If the empty string is specified no output scenario file is generated.
task_file_pathstr, default “”: Path of the task file for the Khiops process (command line option -p of the desktop app). If equal to “” then it writes no task file.
batch_modebool, default True: Deprecated Will be removed in Khiops 11. If True activates batch mode (command line option -b of the app).

check()¶

Checks the types of the command line options

Raises:

TypeError: If any of the command line options does not have the proper type.

class khiops.core.internals.common.SystemSettings(max_cores=None, memory_limit_mb=None, temp_dir='', scenario_prologue='')¶

Bases: object

Khiops system settings

Note

These settings are not available in the CommandLineOptions.

check()¶

Checks the types of the system settings

Raises:

TypeError: If any of the system settings does not have the proper type.
ValueError: If max_cores or memory_limit_mb are set to negative numbers.

khiops.core.internals.common.create_unambiguous_khiops_path(path)¶

Creates a path that is unambiguous for Khiops

Khiops needs that a non absolute path starts with “.” so that it does not use the path of an internally saved state as reference point.

For example: if we open the data table “/some/path/to/data.txt” and then set the results directory simply as “results” the effective location of the results directory will be “/some/path/to/results” instead of “$CWD/results”. This behavior is a feature in the Khiops GUI but it is undesirable when using it as a library.

This function returns a path so that the library behaves as expected: a path relative to the $CWD if it is a non absolute path.

khiops.core.internals.common.deprecation_message(deprecated_feature, deadline_version, replacement=None, quote=True)¶: Formats a deprecation message

khiops.core.internals.common.invalid_keys_message(kwargs)¶: Formats an invalid keyword parameter message

khiops.core.internals.common.is_dict_like(test_object)¶

Returns True if an object is dict-like

An object is dict-like if and only if inherits from the collections.abc.Mapping.

khiops.core.internals.common.is_iterable(test_object)¶: Return True if a container object is iterable, but not string-like

khiops.core.internals.common.is_list_like(list_like)¶

Returns True if an object is list-like

An object is list-like if and only if inherits from collections.abc.Sequence and it is not string-like

khiops.core.internals.common.is_string_like(test_object)¶: Returns True if an object is a valid Python string or sequence of bytes

khiops.core.internals.common.removal_message(removed_feature, since, replacement=None)¶: Formats a feature removal message

khiops.core.internals.common.renaming_message(renamed_feature, new_name, since)¶: Formats a feature renaming message

khiops.core.internals.common.type_error_message(variable_name, variable, *target_types)¶

Formats a type error message

Parameters:

variable_namestr: Name of the variable for whom the type error is signaled.
variableany: Actual variable for whom the type error is signaled.
target_typeslist: Expected types for variable, either as a type or as a string.

Returns:

str: The type error message.
