Volta GPU limited functionalityThis work is rolled over into next release due to dependency on test infrastructure updates. Support for NCCL 2. Now NCCL can be used across machines. User need to enable NCCL in build configure as here. Note After installed the downloaded NCCL 2 package, there are two packages. Install both of them for building CNTK with NCCL 2. Due to issues in system configuration, user might encounter failure during NCCL initialization. To get detailed information about the failure, please set environment variable NCCLDEBUGINFO. There are known issues in current release of NCCL 2 on system configured with Infini. Band devices running in mixed IB and IPo. IB modes. To use IB mode devices only, please set environment variable NCCLIBHCAdevices running on IB mode, e. NCCLIBHCAmlx. 50,mlx. CNTK learner interface update. This update simplifies the learner APIs and deprecates the concepts of unit. Type. minibatch and Unit. Type. sample. The purpose is to make the API intuitive to specify the learner hyper parameters while preserving the unique model update techniques in CNTK the mean gradients of every N samples contributes approximately the same to the model updates regardless of the actual data minibatch sizes. Detailed explanation can be found at the manual on How to Use CNTK Learners. In the new API, all supported learners, including Ada. Delta. SGD, can now be specified bycntk. None, int, or cntk. IGNORE. other learner parameters. There are two major changes lr the learning rate schedule can be specified as a float, a list of floats, or a list of pairs float, int see parameter definition at learningparameterschedule. The same specification applies to the momentum and variancemoment of learners. Nesterov, where such hyper parameters are required. N minibatchsizeN samples contribute to the model updates with the same learning rate even if the actual minibatch size of the data is different from N. This is useful when the data minibatch size varies, especially in scenarios of training with variable length sequences, andor uneven data partition in distributed training. If we set minibatchsizecntk. IGNORE, then we recover the behavior in the literature The mean gradient of the whole minibatch contributes to the model update with the same learning rate. The behavior of ignoring the data minibatch data size is the same as specifying a minibatch size for the learner when the data minibatch size equals to the specified minibatch size. With the new API To have model updates in the same manner as in the classic deep learning literature, we can specify the learner by setting minibatchsizecntk. IGNORE to ignore the minibatch size, e. C. sgdz. parameters, lr 0. C. learners. IGNORE. To enable CNTK specific techniques which apply the same learning rate to the mean gradient of every N samples regardless of the actual minibatch sizes, we can specify the learner by setting minibatchsizeN, e. C. sgdz. parameters, lr 0. Regarding the momentumschedule of the learners FSAda. Grad. and Nesterov, it can be specified in a similar way. Lets use momentumsgd as an example momentumsgdparameters, lrfloat or list of floats, momentumfloat or list of floats. C. learners. IGNORE, epochsizeepochsize. N, epochsizeepochsize. Similar to learningrateschedule, the arguments are interpreted in the same way With minibatchsizeC. IGNORE, the decay momentumbeta is applied to the mean gradient of the whole minibatch regardless of its size. For example, regardless of the minibatch size either be N or 2. N or any size, the mean gradient of such a minibatch will have same decay factor beta. With minibatchsizeN, the decay momentumbeta is applied to the mean gradient of every N samples. For example, minibatches of sizes N, 2. N, 3. N and k. N will have decays of beta, powbeta, 2, powbeta, 3 and powbeta, k respectively the decay is exponential in the proportion of the actual minibatch size to the specified minibatch size. A C. NET API that enables people to build and train networks. Training Support Is Added To C. NET API. With this addition to the existing CNTK C Evaluation API,. NET developers can enjoy fully a integrated deep learning experience. A deep neural network can be built, trained, and validated fully in C while still taking advantage of CNTK performance strength. Users may debug directly into CNTK source code to see how a DNN is trained and evaluated. New features include Basic C Training API. Over 1. 00 basic functions are supported to build a computation network. These functions include Sigmoid, Tanh, Re. LU, Plus, Minus, Convolution, Pooling, Batch. Normalization, to name a few.

Training examples cover a broad range of DNN use cases R binding for CNTKR binding for CNTK, which enables both training and evaluation, will be published in a separate repository very soon. Examples. Object Detection with Fast R CNN and Faster R CNNNew C Eval Examples. We added new C examples CNTKLibrary. CPPEval. CPUOnly. Examples and CNTKLibrary. CPPEval. GPUExamples. They illustrate how to use C CNTK Library for model evaluation on CPU and GPU. Another new example is UWPImage. Recognition, which is an example using CNTK UWP library for model evaluation. New C Eval examples. We added an example for asynchronous evaluation Evaluation. Single. Image. Async. One thing we shall point out is CNTK C API does not have an asynchronous method for Evaluate, because the evaluation is a CPU bound operation Please refer to this article for detailed explanation. However, it is desired to run evaluation asynchronously in some use cases, e.
