From 201e0fee596dafcf9c869a550fae29779aad2394 Mon Sep 17 00:00:00 2001 From: Sang-Hoon Park Date: Wed, 27 Jan 2021 13:14:56 +0000 Subject: Make Softmax kernels on OpenCL stateless * ClSoftmaxKernel and ClSoftmax are created. * ClSoftmaxKernel is now state-less and ClSoftmax handles the internal tensors required for computation. * add_const_tensor() is added to TensorPack not only to have symmetric interface but also to benefit from implicit conversion.
