جمع شرائح من params
وفقا indices
.
ملخص يجب أن تكون indices
عددًا صحيحًا موترًا لأي بُعد (عادةً 0-D أو 1-D). يُنتج موتر إخراج ذو شكل indices.shape + params.shape[1:]
حيث:
# Scalar indices
output[:, ..., :] = params[indices, :, ... :]
# Vector indices
output [ i, :, ..., : ] = params [ indices[i ] , : , ... :]
# Higher rank indices
output[i, ..., j, :, ... :] = params[indices[i, ..., j], :, ..., :] إذا كانت indices
عبارة عن تبديل وكانت len(indices) == params.shape[0]
، فستقوم هذه العملية بتبديل params
وفقًا لذلك.
validate_indices
: تم إهماله. إذا تم تعيين هذه العملية إلى وحدة المعالجة المركزية، فسيتم دائمًا التحقق من صحة القيم الموجودة في indices
لتكون ضمن النطاق. إذا تم تعيينها إلى وحدة معالجة الرسومات، فإن المؤشرات الخارجة عن الحدود تؤدي إلى سلوك آمن ولكن غير محدد، والذي قد يتضمن ظهور خطأ.
