SUMMARY

A generic multidimensional NumPy array.

python
from telekinesis import datatypes
array = datatypes.Array([1, 2, 5])

Parameters ​

ParameterTypeDefaultDescription
datanp.ndarray | list | tupleRequiredThe array-like data to store, with a supported dtype (see below).

Raises ​

ExceptionCondition
TypeErrordata can't be converted into a uniform array (e.g. ragged nested lists)
ValueErrorThe resulting dtype is unsupported (see Supported Dtypes below)

Supported Dtypes ​

CategoryDtypes
Booleanbool
Signed / unsigned integerint8…int64, uint8…uint64
Floating-pointfloat16, float32, float64

object, structured, datetime64, and complex (complex64/complex128) dtypes are not supported.

Attributes ​

AttributeTypeDescription
datanp.ndarrayThe wrapped array. Reading it returns a copy, so mutating the result doesn't affect the Array; assigning a new value re-validates it the same way as construction.
shapetuple[int, ...]Shape of the array.
ndimintNumber of dimensions.
dtypenp.dtypeDtype of the array.
sizeintTotal number of elements.

Methods ​

MethodTypeDescription
Array.coerce(value, name="value")ArrayConverts array-like data into an Array. Accepts a np.ndarray, list, or tuple. If value is already an Array, it is returned unchanged. The optional name is only used to make validation error messages more descriptive.
to_numpy(copy=True)np.ndarrayReturns the data as a plain array. With the default copy=True you get an independent copy; pass copy=False to get a direct reference to the internal array instead, so mutating it also mutates the Array.
copy()ArrayReturns a new, independent Array with the same data.

Operators ​

OperationBehavior
arr == otherCompare with another Array value.
len(arr)Returns the length of the first axis.
np.asarray(arr)Convert to a NumPy array with np.asarray(arr).

Visualization ​

python
import rerun as rr

# Your code block
# ....

rr.init("array_example", spawn=True)
datatypes.visualize(array, entity_path="/array", label="Array")
