### corpora {#config-corpora tag="section"}
This section defines a dictionary mapping of string keys to `Callable`
functions. Each callable takes an `nlp` object and yields
[`Example`](/api/example) objects. By default, the two keys `train` and `dev`
are specified and each refer to a [`Corpus`](/api/top-level#Corpus). When
pretraining, an additional pretrain section is added that defaults to a
[`JsonlReader`](/api/top-level#JsonlReader).
These subsections can be expanded with additional subsections, each referring to
a callback of type `Callable[[Language], Iterator[Example]]`:
> #### Example
>
> ```ini
> [corpora]
> [corpora.train]
> @readers = "spacy.Corpus.v1"
> path = ${paths:train}
>
> [corpora.dev]
> @readers = "spacy.Corpus.v1"
> path = ${paths:dev}

> [corpora.pretrain]
> @readers = "spacy.JsonlReader.v1"
> path = ${paths.raw}
> min_length = 5
> max_length = 500
>
> [corpora.mydata]
> @readers = "my_reader.v1"
> shuffle = true
> ```
Alternatively, the `corpora` block could refer to one function with return type
`Dict[str, Callable[[Language], Iterator[Example]]]`:
> #### Example
>
> ```ini
> [corpora]
> @readers = "my_dict_reader.v1"
> train_path = ${paths:train}
