# init(labeledByNamesAt:separator:index:type:continueOnFailure:)

Reads training examples from a directory containing files having their labels in the name. The name can contain multiple words separated by a separator. So the index tells the position of the label in the file name. Files with incorrect name format are ignored.

## Declaration

```swift
init(labeledByNamesAt url: URL, separator: Character = ".", index: Int = 0, type: UTType, continueOnFailure: Bool = false) throws
```

## Parameters

- `url`: URL of directory containing the files.
- `separator`: The separator used in the name. Default value is “.”
- `index`: Index of the label in the file name. Default value is 0.
- `type`: Type of files.
- `continueOnFailure`: A Boolean value indicating whether to continue reading files after encountering a file that is not readable. The default value is false.

## Discussion

Discussion Take for example this directory structure: /     fold1-foo-file1.png     fold1-foo-file2.png     fold2-foo-file3.png     fold1-bar-file4.png     fold1-bar-file5.png     fold2-bar-file6.png When we specify separator as “-” and index as 1, it would produce two labels (foo and bar) with three URLs each.
