class linopy.variables.Variables(data, model, _label_position_index=None)

A variables container used for storing multiple variable arrays.

__init__(data, model, _label_position_index=None)

Methods

__init__(data, model[, _label_position_index])
add(variable)	Add a variable to the variables container.
fix([value, decimals, overwrite])	Fix all variables in this container to their solution or a scalar value.
format_labels(values)	Get a string representation of a selection of variable labels.
get_blockmap([dtype])	Get a one-dimensional array mapping the variables to blocks.
get_label_position(values)	Get tuple of name and coordinate for variable labels.
get_label_position_with_index(label)	Get name, coordinate, and raw numpy index for a single variable label.
get_label_range(name)	Get starting and ending label for a variable.
get_name_by_label(label)	Get the variable name of the variable containing the passed label.
get_solver_attribute(attr)	Get an attribute from the solver model.
items()
print_labels(values)	Print a selection of labels of the variables.
relax()	Relax integrality of all integer/binary variables in this container.
remove(name)	Remove variable name from the variables.
reset_solution()	Reset the stored solution of variables.
set_blocks(blocks)	Get a dataset of same shape as variables.labels indicating the blocks.
unfix()	Unfix all variables in this container.
unrelax()	Restore integrality of all previously relaxed variables in this container.
