# Menghentikan model Label Kustom Rekognition Amazon
Anda dapat berhenti menjalankan model Amazon Rekognition Custom Labels dengan menggunakan konsol atau dengan menggunakan operasi. [StopProjectVersion](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_StopProjectVersion)

## Menghentikan model Label Kustom Rekognition Amazon (Konsol)
Gunakan prosedur berikut untuk menghentikan model Amazon Rekognition Custom Labels yang sedang berjalan dengan konsol. Anda dapat menghentikan model langsung dari konsol atau menggunakan kode AWS SDK yang disediakan oleh konsol.
**Untuk menghentikan model (konsol)**
1. Buka konsol Amazon Rekognition di. [https://console.aws.amazon.com/rekognition/](https://console.aws.amazon.com/rekognition/)
1. Pilih **Gunakan Label Kustom**.
1. Pilih **Mulai**.
1. Di panel navigasi kiri, pilih **Proyek**.
1. Pada halaman Sumber daya **proyek**, pilih proyek yang berisi model terlatih yang ingin Anda hentikan.
1. Di bagian **Model**, pilih model yang ingin Anda hentikan.
1. Pilih tab **Gunakan model**.
1.
------
#### [ Stop model using the console ]
1. Di bagian **Mulai atau hentikan model**, pilih **Berhenti**.
1. Dalam kotak dialog **Stop model**, masukkan **stop** untuk mengonfirmasi bahwa Anda ingin menghentikan model.
1. Pilih **Berhenti** untuk menghentikan model Anda.
------
#### [ Stop model using the AWS SDK ]
Di bagian **Gunakan model Anda** lakukan hal berikut:
1. Pilih **Kode API.**
1. **Pilih **AWS CLI** atau Python.**
1. Dalam **model Stop** salin kode contoh.
1. Gunakan kode contoh untuk menghentikan model Anda. Untuk informasi selengkapnya, lihat [Menghentikan model Label Kustom Rekognition Amazon (SDK)](#rm-stop-sdk).
------
1. Pilih nama proyek Anda di bagian atas halaman untuk kembali ke halaman ikhtisar proyek.
1. Di bagian **Model**, periksa status model. Model telah berhenti ketika status model **BERHENTI**.
## Menghentikan model Label Kustom Rekognition Amazon (SDK)
Anda menghentikan model dengan memanggil [StopProjectVersion](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_StopProjectVersion)API dan meneruskan Amazon Resource Name (ARN) model dalam parameter `ProjectVersionArn` input.
Seorang model mungkin membutuhkan waktu beberapa saat untuk berhenti. Untuk memeriksa status saat ini, gunakan`DescribeProjectVersions`.
**Untuk menghentikan model (SDK)**
1. Jika Anda belum melakukannya, instal dan konfigurasikan AWS CLI dan AWS SDKs. Untuk informasi selengkapnya, lihat [Langkah 4: Mengatur AWS CLI dan AWS SDKs](su-awscli-sdk.md).
1. Gunakan kode contoh berikut untuk menghentikan model yang sedang berjalan.
------
#### [ CLI ]
Ubah nilai `project-version-arn` ke ARN dari versi model yang ingin Anda hentikan.
```
aws rekognition stop-project-version --project-version-arn "model arn" \
--profile custom-labels-access
```
------
#### [ Python ]
Contoh berikut menghentikan model yang sudah berjalan.
Sediakan parameter baris perintah berikut:
+ `project_arn`— ARN dari proyek yang berisi model yang ingin Anda hentikan.
+ `model_arn`— ARN dari model yang ingin Anda hentikan.
