Attributes#
- osl_dynamics.utils.misc.nextpow2(x)[source]#
Next power of 2.
- Parameters:
x (int) – Any integer.
- Returns:
res – The smallest power of two that is greater than or equal to the absolute value of x.
- Return type:
int
- osl_dynamics.utils.misc.leading_zeros(number, largest_number)[source]#
Pad a number with leading zeros.
This is useful for creating a consistent naming scheme for files.
- Parameters:
number (int) – Number to be padded.
largest_number (int) – Largest number in the set.
- Returns:
padded_number – Number padded with leading zeros.
- Return type:
str
- osl_dynamics.utils.misc.override_dict_defaults(default_dict, override_dict=None)[source]#
Helper function to update default dictionary values with user values.
- Parameters:
default_dict (dict) – Dictionary of default values.
override_dict (dict, optional) – Dictionary of user values.
- Returns:
new_dict – default_dict with values replaced by user values.
- Return type:
dict
- osl_dynamics.utils.misc.listify(obj)[source]#
Create a list from any input.
If
None
is passed, return an empty list. If a list is passed, return the list. If a tuple is passed, return it as a list. If any other object is passed, return it as a single item list.- Parameters:
obj (Any) – Object to be transformed to a list.
- Return type:
Object as a list.
- osl_dynamics.utils.misc.replace_argument(func, name, item, args, kwargs, append=False)[source]#
Replace arguments in function calls.
- Parameters:
func (callable) – The function being called.
name (str) – Name of the variable to be modified.
item – The value to be added.
args (dict) – Original arguments.
kwargs (dict) – Original keyword arguments.
append (bool, optional) – Whether the value should be appended or replace the existing argument.
- Returns:
args (list) – Arguments.
kwargs (dict) – Keyword arguments.
- osl_dynamics.utils.misc.get_argument(func, name, args, kwargs)[source]#
Get an argument passed to a function call whether it is a normal argument or keyword argument.
- Parameters:
func (callable) – The function being called.
name (str) – Name of the variable to be modified.
args (dict) – Arguments.
kwargs (dict) – Keyword arguments.
- Returns:
args – Argument.
- Return type:
argument
- osl_dynamics.utils.misc.check_arguments(args, kwargs, index, name, value, comparison_op)[source]#
Checks the arguments passed to a function.
- Parameters:
args (list) – Arguments.
kwargs (dict) – Keyword arguments.
index (int) – Index of argument.
name (str) – Name of keyword argument.
value – Value to compare to given argument.
comparison_op (func) – Comparison operation for checking the original.
- Returns:
valid – If the given value is valid as determined by the comparison operation.
- Return type:
bool
- osl_dynamics.utils.misc.array_to_memmap(filename, array)[source]#
Save an array and reopen it as a np.memmap.
- Parameters:
filename (str) – The name of the file to save to.
array (np.ndarray) – The array to save.
- Returns:
memmap – Memory map.
- Return type:
np.memmap
- class osl_dynamics.utils.misc.MockFlags(shape, c_contiguous=True)[source]#
Flags for memmap header construction.
- Parameters:
shape (list of int) – The shape of the array being mapped.
c_contiguous (bool, optional) – Is the array C contiguous or F contiguous?
- class osl_dynamics.utils.misc.MockArray(shape, dtype=np.float64, c_contiguous=True)[source]#
Create an empty array on disk without creating it in memory.
- Parameters:
shape (list of int) – Dimensions or the array being created.
dtype (type) – The data type of the array.
c_contiguous (bool, optional) – Is the array C contiguous or F contiguous?
- osl_dynamics.utils.misc.save(filename, array)[source]#
Save a file.
- Parameters:
filename (str) – Path to file to save to. Must be ‘.npy’ or ‘.pkl’.
array (np.ndarray or list) – Array to save.
- osl_dynamics.utils.misc.load(filename, **kwargs)[source]#
Load a file.
- Parameters:
filename (str) – Path to file to load. Must be ‘.npy’ or ‘.pkl’.
- Returns:
array – Array loaded from the file.
- Return type:
np.ndarray or list
