Mengelola model

Anda membuat model kustom dengan melatihnya menggunakan set data yang telah disiapkan. AutoML Vision menggunakan item dari set data untuk melatih model, mengujinya, dan evaluate performanya. Anda meninjau hasilnya, menyesuaikan set data pelatihan sesuai kebutuhan, dan melatih model baru menggunakan set data yang telah ditingkatkan.

Proses pelatihan model dapat memakan waktu beberapa jam untuk diselesaikan. AutoML API memungkinkan Anda memeriksa status pelatihan.

Karena AutoML Vision membuat model baru setiap kali Anda memulai pelatihan, project Anda dapat menyertakan banyak model. Anda bisa mendapatkan daftar model di project dan dapat menghapus model yang tidak lagi diperlukan.

Model listingan

Bagian ini menjelaskan cara mengambil daftar model yang tersedia untuk sebuah project.

UI web

Untuk melihat daftar model yang tersedia menggunakan Vision Dashboard, klik ikon bola lampu di menu navigasi kiri.

Daftar model

Untuk melihat model project yang berbeda, pilih project dari menu drop-down di kanan atas panel judul.

REST

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

  • project-id: Project ID GCP Anda.

Metode HTTP dan URL: 

GET https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/models

Untuk mengirim permintaan Anda, pilih salah satu opsi berikut:

curl

Jalankan perintah berikut: 

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: project-id" \
     "https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/models"

PowerShell

Jalankan perintah berikut: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/models" | Select-Object -Expand Content

Anda akan menerima respons JSON yang mirip dengan contoh berikut. Respons ini menampilkan informasi tentang dua model yang dihosting di Cloud.

Memperbarui Nomor Node Model

Setelah memiliki model yang di-deploy dan dilatih, Anda dapat memperbarui jumlah node tempat model di-deploy untuk merespons jumlah traffic tertentu. Misalnya, jika Anda mendapati jumlah kueri per detik (QPS) yang lebih tinggi dari yang diperkirakan.

Anda dapat mengubah nomor node ini tanpa harus membatalkan deployment model terlebih dahulu. Memperbarui deployment akan mengubah nomor node tanpa mengganggu traffic prediksi yang Anda salurkan.

UI web

  1. Di Vision Dashboard pilih tab Models di menu navigasi sebelah kiri untuk menampilkan model yang tersedia.

    Untuk melihat model project yang berbeda, pilih project dari menu drop-down di kanan atas panel judul.

  2. Pilih model terlatih yang telah di-deploy.
  3. Pilih tab Pengujian & Penggunaan tepat di bawah panel judul.

  4. Pesan akan ditampilkan dalam kotak di bagian atas halaman yang bertuliskan "Model Anda telah di-deploy dan tersedia untuk permintaan prediksi online". Pilih opsi Update deployment di samping teks ini.

    gambar tombol update deployment
  5. Di jendela Update deployment yang terbuka, pilih nomor node baru untuk men-deploy model Anda dari daftar. Nomor node menampilkan perkiraan kueri prediksi per detik (QPS). gambar jendela pop-up update deployment

  6. Setelah memilih nomor node baru dari daftar, pilih Update deployment untuk memperbarui nomor node tempat model di-deploy.

    memperbarui jendela deployment setelah memilih nomor node baru
  7. Anda akan dikembalikan ke jendela Test & Use tempat Anda melihat kotak teks sekarang menampilkan "Deploying model...". deployment model

  8. Setelah model berhasil di-deploy pada nomor node baru, Anda akan menerima email di alamat yang terkait dengan project Anda.

REST

Metode yang sama yang Anda gunakan untuk men-deploy model di awal juga digunakan untuk mengubah nomor node model yang di-deploy.

Sebelum menggunakan salah satu data permintaan, buat pengganti berikut:

  • project-id: Project ID GCP Anda.
  • model-id: ID model Anda, dari respons saat membuat model. ID adalah elemen terakhir dari nama model Anda. Misalnya:
    • nama model: projects/project-id/locations/location-id/models/IOD4412217016962778756
    • ID Model: IOD4412217016962778756

Pertimbangan kolom:

  • nodeCount - Jumlah node tempat model akan di-deploy. Nilainya harus antara 1 dan 100, inklusif di kedua ujungnya. Node adalah abstraksi resource mesin, yang dapat menangani kueri prediksi online per detik (QPS) seperti yang diberikan dalam qps_per_node model.

Metode HTTP dan URL: 

POST https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/models/MODEL_ID:deploy

Isi JSON permintaan: 

{
  "imageClassificationModelDeploymentMetadata": {
    "nodeCount": 2
  }
}

Untuk mengirim permintaan Anda, pilih salah satu opsi berikut:

curl

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: project-id" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/models/MODEL_ID:deploy"

PowerShell

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/models/MODEL_ID:deploy" | Select-Object -Expand Content

Anda akan melihat output yang serupa dengan berikut ini: Anda dapat menggunakan ID operasi untuk mendapatkan status tugas. Untuk mengetahui contohnya, lihat Bekerja dengan operasi yang berjalan lama

Menghapus model

Contoh berikut akan menghapus model.

UI web

  1. Di Vision Dashboard, klik ikon bola lampu di menu navigasi sebelah kiri untuk menampilkan daftar model yang tersedia.

  2. Klik menu tiga titik di ujung kanan baris yang ingin Anda hapus, lalu pilih Delete model.

  3. Klik Hapus di kotak dialog konfirmasi.

    Menghapus model

REST

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

  • project-id: Project ID GCP Anda.
  • model-id: ID model Anda, dari respons saat membuat model. ID adalah elemen terakhir dari nama model Anda. Misalnya:
    • nama model: projects/project-id/locations/location-id/models/IOD4412217016962778756
    • id model: IOD4412217016962778756

Metode HTTP dan URL: 

DELETE https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-
central1/models/MODEL_ID

Untuk mengirim permintaan Anda, pilih salah satu opsi berikut:

curl

Jalankan perintah berikut: 

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: project-id" \
     "https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-
central1/models/MODEL_ID"

PowerShell

Jalankan perintah berikut: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -Uri "https://automl.googleapis.com/v1/projects/PROJECT_ID/locations/us-
central1/models/MODEL_ID" | Select-Object -Expand Content
