LazyArray#
This is an interface for evaluating an expression or a Python user defined function.
You can get an object following the LazyArray API with any of the following ways:
Any expression that involves one or more NDArray objects. e.g.
a + b
, where a and b are NDArray objects (see a tutorial).Using the lazyexpr constructor.
Using the lazyudf constructor (see its tutorial).
See the LazyExpr and LazyUDF sections for more information.
Methods#
LazyExpr#
For getting a LazyArray-compliant object from an expression (à la numexpr), you can use the lazyexpr constructor.
Get a LazyExpr from an expression. |
LazyUDF#
For getting a LazyArray-compliant object from a user-defined Python function, you can use the lazyudf constructor.
Get a LazyUDF from a python user-defined function. |
