<p>SINGA is a distributed deep learning library.</p>
<p>This release includes following changes:</p>
<ul>
<li><p>Tensor core:</p>
<ul>
<li>Support tensor transformation (reshape, transpose) for tensors up to 6
dimensions.</li>
<li>Implement traverse_unary_transform in Cuda backend, which is similar to CPP
backend one.</li>
</ul></li>
<li><p>Add new tensor operators into the autograd module, including CosSim,
DepthToSpace, Embedding, Erf, Expand, Floor, Pad, Round, Rounde, SpaceToDepth,
UpSample, Where. The corresponding ONNX operators are thus supported by SINGA.</p></li>
<li><p>Add Embedding and Gemm into the layer module.</p></li>
<li><p>Add SGD operators to opt module, including RMSProp, Adam, and AdaGrad.</p></li>
<li><p>Extend the sonnx module to support DenseNet121, ShuffleNetv1, ShuffleNetv2,
SqueezeNet, VGG19, GPT2, and RoBERTa.</p></li>
<li><p>Reconstruct sonnx to</p>
<ul>
<li>Support creating operators from both layer and autograd.</li>
<li>Re-write SingaRep to provide a more powerful intermediate representation of
SINGA.</li>
<li>Add a SONNXModel which implements from Model to provide uniform API and
features.</li>
</ul></li>
<li><p>Add one example that trains a BiLSTM model over the InsuranceQA data.</p></li>
<li><p>Replace the Travis CI with Github workflow. Add quality and coverage
management.</p></li>
<li><p>Add compiling and packaging scripts to creat wheel packages for distribution.</p></li>
<li><p>Fix bugs</p>
<ul>
<li>Fix IMDB LSTM model example training script.</li>
<li>Fix Tensor operation Mult on Broadcasting use cases.</li>
<li>Gaussian function on Tensor now can run on Tensor with odd size.</li>
<li>Updated a testing helper function gradients() in autograd to lookup param
gradient by param python object id for testing purpose.</li>
</ul></li>
</ul>
