Memahami ringkasan manifes

Ringkasan manifes berisi informasi berikut.

• Informasi kesalahan tentang Kesalahan konten manifes terminal ditemui selama validasi.

• Informasi lokasi kesalahan untuk Kesalahan validasi baris JSON non terminal dalam kumpulan data pelatihan dan pengujian.

• Statistik kesalahan seperti jumlah total Garis JSON yang tidak valid yang ditemukan dalam kumpulan data pelatihan dan pengujian.

Ringkasan manifes dibuat selama pelatihan jika tidak adaKesalahan file manifes terminal. Untuk mendapatkan lokasi file ringkasan manifes (manifest_summary.json), lihat. Mendapatkan hasil validasi

catatan

Kesalahan layanan dan kesalahan file manifes tidak dilaporkan dalam ringkasan manifes. Untuk informasi selengkapnya, lihat Kesalahan terminal.

Untuk informasi tentang kesalahan konten manifes tertentu, lihatKesalahan konten manifes terminal.

Format file ringkasan manifes

File manifes memiliki 2 bagian, statistics danerrors.

statistik

statisticsberisi informasi tentang kesalahan dalam kumpulan data pelatihan dan pengujian.

• training— statistik dan kesalahan yang ditemukan dalam dataset pelatihan.

• testing— statistik dan kesalahan yang ditemukan dalam dataset pengujian.

Objek dalam errors array berisi kode kesalahan dan pesan untuk kesalahan konten manifes.

error_line_indicesArray berisi nomor baris untuk setiap Garis JSON dalam manifes pelatihan atau pengujian yang memiliki kesalahan. Untuk informasi selengkapnya, lihat Memperbaiki kesalahan pelatihan.

kesalahan

Kesalahan yang mencakup kumpulan data pelatihan dan pengujian. Misalnya, ERROR_INSUFFICIENT_USABLE_LABEL_TUMPANG TINDIH terjadi ketika tidak ada cukup label yang dapat digunakan yang tumpang tindih dengan kumpulan data pelatihan dan pengujian.
