Résumé
indices doivent être un tenseur entier de n'importe quelle dimension (généralement 0-D ou 1-D). Produit un tenseur de sortie avec la forme indices.shape + params.shape[1:] où :
Si indices sont une permutation et len(indices) == params.shape[0] alors cette opération permutera params en conséquence.
validate_indices : obsolète. Si cette opération est affectée au processeur, les valeurs des indices sont toujours validées pour être dans la plage. S'ils sont attribués au GPU, les index hors limites entraînent un comportement sûr mais non spécifié, qui peut inclure la génération d'une erreur.
