You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: detector.go
    path of file: ./repos/photoprism/internal/nsfw
    
    the code of the file until where you have to start completion: package nsfw

import (
	"bufio"
	"fmt"
	"os"
	"path/filepath"
	"sync"

	"github.com/photoprism/photoprism/pkg/clean"
	"github.com/photoprism/photoprism/pkg/fs"
	tf "github.com/tensorflow/tensorflow/tensorflow/
    
func (t *Detector) File(filename string) (result Labels, err error) {
	if fs.MimeType(filename) != "image/jpeg" {
		return result, fmt.Errorf("nsfw: %s is not a jpeg file", clean.Log(filepath.Base(filename)))
	}

	imageBuffer, err := os.ReadFile(filename)

	if err != nil {
		return result, err
	}

	return t.Labels(imageBuffer)
}
