Build Lightweight Python Components

Lightweight Python components do not require you to build a new container imagefor every code change. They’re intended for fast iteration in a notebookenvironment.

Advantages over container components:

• Faster iteration: No need to build new container image after every change(building images takes some time).

There are several requirements for the component function:

• The function must be stand-alone.

  • It should not use any code declared outside the function definition.
  • Any imports should be added inside the main component function.
• • If you need to import a package that’s not available in the default baseimage you can try to find a container image that already includes therequired packages. (As a workaround you can use the subprocess moduleto run for the required package.)

• If the function operates on numbers, the parameters must have type hints.Supported types are int, , bool. All other arguments are passed asstrings.
