View Source Nx.Backend behaviour (Nx v0.7.2)

The behaviour for tensor backends.

Each backend is module that defines a struct and implements the callbacks defined in this module. The callbacks are mostly implementations of the functions in the Nx module with the tensor output shape given as first argument.

Nx backends come in two flavors: opaque backends, of which you should not access its data directly except through the functions in the Nx module, and public ones, of which its data can be directly accessed and traversed. The former typically have the Backend suffix.

Nx ships with the following backends:

  • Nx.BinaryBackend - an opaque backend written in pure Elixir that stores the data in Elixir's binaries. This is the default backend used by the Nx module. The backend itself (and its data) is private and must not be accessed directly.

  • Nx.TemplateBackend - an opaque backend written that works as a template in APIs to declare the type, shape, and names of tensors to be expected in the future.

  • Nx.Defn.Expr - a public backend used by defn to build expression trees that are traversed by custom compilers.

This module also includes functions that are meant to be shared across backends.

inspect(map, binary, inspect_opts)

View Source

Inspects the given tensor given by binary.

Note the binary may have fewer elements than the tensor size but, in such cases, it must strictly have more elements than inspect_opts.limit

Options

The following must be passed through Inspect :custom_options

  • :nx_precision - Configures the floating-point number printing precision. If set, will print floating-point numbers in scientific notation using the specified number of significant digits. Otherwise, default Elixir printing rules are applied.
