> Predicting film genres from their posters with Tensorflow.js > Predicting film genres from their posters with Tensorflow.js
## Dataset
The dataset used with this demo can be found here:
https://nextcloud.starbeamrainbowlabs.com/index.php/s/wmCdL4tX3HHGAFD To use:
The format is as follows:
```
+ dataset_dir/
+ train/
+ 1234,Comedy,Fantasy.jpg
+ 4321,Western,Short,Drama.jpg
+ .....
+ validate/
+ 6789,Drama,Mystery,Thriller.jpg
+ 9876,History,Documentary,Animation.jpg
+ .....
```
The filenames of the images take the following format: `ID,GENRE_1,GENRE_2,GENRE_N.jpg`.
## System / User Requirements
- [Node.js](https://nodejs.org/)
- [NPM](https://www.npmjs.com/) (installed by default with Node.js)
- A relatively decent CPU
- Basic knowledge of the command-line / terminal
## Installation
First, clone this git repo:
```bash ```bash
git clone https://git.starbeamrainbowlabs.com/Demos/film-poster-genres.git node src/index.mjs train --input datasets/posters-256/ --output output/
cd film-poster-genres node src/index.mjs predict --input datasets/posters-256/validate/25410,Comedy,Family,Drama.jpg --ai-model output/checkpoints/49 2>/dev/null
```
Then, install the dependencies:
```bash
npm install
```
## Usage
### Training
To train a new model:
```bash
node src/index.mjs train --input path/to/dataset_dir --output path/to/output_dir
```
The output directory will look like this:
```
+ output_dir/
+ metrics.stream.json
+ checkpoints/
+ 0/
+ 1/
+ 2/
+ 3/
``` ```
## Predicting TODO: Fill out this README (and maybe move it to GitHub & make this repo a clone)
To make a prediction using an existing model:
```bash
node src/index.mjs predict --input path/to/image.jpg --ai-model path/to/checkpoint_dir/
```
The result will be written to the standard output. Extra debugging data is written to the standard error, but this can be ignored.
