|
||
<p>The PyTorch v1.4.0 release is now available.</p>
|
||
<p>The release contains over 1,500 commits and a significant amount of effort in areas spanning existing areas like JIT, ONNX, Distributed, Performance and Eager Frontend Improvements and improvements to experimental areas like mobile and quantization. It also contains new experimental features including rpc-based model parallel distributed training and language bindings for the Java language (inference only).</p>
|
||
<p><strong>PyTorch 1.4 is the last release that supports Python 2</strong>. For the C++ API, it is the last release that supports C++11: you should start migrating to Python 3 and building with C++14 to make the future transition from 1.4 to 1.5 easier.</p>
|
||
<h1>Highlights</h1>
|
||
<h2>PyTorch Mobile - Build level customization</h2>
|
||
<p>Following the experimental release of <a href="https://pytorch.org/blog/pytorch-1-dot-3-adds-mobile-privacy-quantization-and-named-tensors/" rel="nofollow">PyTorch Mobile in the 1.3 release</a>, PyTorch 1.4 adds additional mobile support including the ability to customize build scripts at a fine-grain level. This allows mobile developers to optimize library size by only including the operators used by their models and, in the process, reduce their on device footprint significantly. Initial results show that, for example, a customized MobileNetV2 is 40% to 50% smaller than the prebuilt PyTorch mobile library. <a href="https://pytorch.org/mobile/home/" rel="nofollow">Learn more</a> about how to create your own custom builds, and please engage with the community on the <a href="https://discuss.pytorch.org/c/mobile" rel="nofollow">PyTorch forums</a> to provide any feedback you have.</p>
|
||
<h2>Distributed Model Parallel Training [Experimental]</h2>
|
||
<p>With the scale of models, such as RoBERTa, continuing to increase into the billions of parameters, model parallel training has become ever more important to help researchers push the limits. This release provides a distributed RPC framework to support distributed model parallel training. It allows for running functions remotely and referencing remote objects without copying the real data around, and provides autograd and optimizer APIs to transparently run backwards and update parameters across RPC boundaries.</p>
|
||

|
||
<h2>Java bindings [Experimental]</h2>
|
||
<p>In addition to supporting Python and C++, this release adds experimental support for Java bindings. Based on the interface developed for Android in PyTorch Mobile, the new bindings allow you to invoke TorchScript models from any Java program. Note that the Java bindings are only available for Linux for this release, and for inference only. We expect support to expand in subsequent releases. See the code snippet below for how to use PyTorch within Java:</p>
|
||

|
||
<h2>Pruning</h2>
|
||
<p>Pruning functionalities have been added to PyTorch in the <code>nn.utils.prune</code> module. This provides out-of-the-box support for common magnitude-based and random pruning techniques, both structured and unstructured, both layer-wise and global, and it also enables custom pruning from user-provided masks.</p>
|
||
<p>To prune a tensor, first select a pruning technique among those available in <code>nn.utils.prune</code> (or implement your own by subclassing <code>BasePruningMethod</code>).</p>
|
||
<div class="highlight highlight-source-python"><pre><span class="pl-k">from</span> torch.nn.utils <span class="pl-k">import</span> prune
|
||
t <span class="pl-k">=</span> torch.rand(<span class="pl-c1">2</span>, <span class="pl-c1">5</span>)
|
||
p <span class="pl-k">=</span> prune.L1Unstructured(<span class="pl-v">amount</span><span class="pl-k">=</span><span class="pl-c1">0.7</span>)
|
||
pruned_tensor <span class="pl-k">=</span> p.prune(t)</pre></div>
|
||
<p>To prune a module, select one of the pruning functions available in <code>nn.utils.prune</code> (or implement your own) and specify which module and which parameter within that module pruning should act on.</p>
|
||
<div class="highlight highlight-source-python"><pre>m <span class="pl-k">=</span> nn.Conv2d(<span class="pl-c1">3</span>, <span class="pl-c1">1</span>, <span class="pl-c1">2</span>)
|
||
prune.ln_structured(<span class="pl-v">module</span><span class="pl-k">=</span>m, <span class="pl-v">name</span><span class="pl-k">=</span><span class="pl-s"><span class="pl-pds">'</span>weight<span class="pl-pds">'</span></span>, <span class="pl-v">amount</span><span class="pl-k">=</span><span class="pl-c1">5</span>, <span class="pl-v">n</span><span class="pl-k">=</span><span class="pl-c1">2</span>, <span class="pl-v">dim</span><span class="pl-k">=</span><span class="pl-c1">1</span>)</pre></div>
|
||
<p>Pruning reparametrizes the module by turning <code>weight</code> (in the example above) from a parameter to an attribute, and replacing it with a new parameter called <code>weight_orig</code> (i.e. appending <code>"_orig"</code> to the initial parameter <code>name</code>) that stores the unpruned version of the tensor. The pruning mask is stored as a buffer named <code>weight_mask</code> (i.e. appending <code>"_mask"</code> to the initial parameter <code>name</code>). Pruning is applied prior to each forward pass by recomputing <code>weight</code> through a multiplication with the updated mask using PyTorch's <code>forward_pre_hooks</code>.</p>
|
||
<p>Iterative pruning is seamlessly enabled by repeatedly calling pruning functions on the same parameter (this automatically handles the combination of successive masks by making use of a <code>PruningContainer</code> under the hood).</p>
|
||
<p><code>nn.utils.prune</code> is easily extensible to support new pruning functions by subclassing the <code>BasePruningMethod</code> base class and implementing the <code>compute_mask</code> method with the instructions to compute the mask according to the logic of the new pruning technique.</p>
|
||
<h1>Backwards Incompatible Changes</h1>
|
||
<h2>Python</h2>
|
||
<h3><code>torch.optim</code>: It is no longer supported to use <code>Scheduler.get_lr()</code> to obtain the last computed learning rate. to get the last computed learning rate, call <code>Scheduler.get_last_lr()</code> instead. (<a href="https://github.com/pytorch/pytorch/pull/26423" data-hovercard-type="pull_request" data-hovercard-url="/pytorch/pytorch/pull/26423/hovercard">26423</a>)</h3>
|
||
<p>Learning rate schedulers are now “chainable,” as mentioned in the <em>New Features</em> section below. <code>Scheduler.get_lr</code> was sometimes used for monitoring purposes to obtain the current learning rate. But since <code>Scheduler.get_lr</code> is also used internally for computing new learning rates, this actually returns a value that is “one step ahead.” To get the last computed learning rate, use <code>Scheduler.get_last_lr</code> instead.</p>
|
||
<p>Note that <code>optimizer.param_groups[0]['lr']</code> was in version 1.3.1 and remains in 1.4.0 a way of getting the current learning rate used in the optimizer.</p>
|
||
<h3><code>Tensor.unfold</code> on a 0-dimensional Tensor now properly returns a 1-dimensional Tensor.</h3>

<li>Remove<code> torch.jit._register_*</code> bindings from Python (e.g. <code>torch.jit._register_attribute</code>). These were private functions that were not intended to be used.

<h2>C++</h2>

<h3>[C++] The distinction between Tensor and Variable has been eliminated at the C++ level. (<a href="https://github.com/pytorch/pytorch/pull/28287" data-hovercard-type="pull_request" data-hovercard-url="/pytorch/pytorch/pull/28287/hovercard">28287</a>)</h3>
|
||
<p>This change simplifies our C++ API and matches previous changes we did at the python level that merged Tensors and Variables into a single type.</p>
|
||
<p>This change is unlikely to affect user code; the most likely exceptions are:</p>
|
||
<ol>
|
||
<li>
|
||
<p><a href="https://en.cppreference.com/w/cpp/language/adl" rel="nofollow">Argument-dependent lookup</a> for <code>torch::autograd</code> may no longer work. This can break because Variable is now defined as an alias for Tensor (<code>using Variable = Tensor;</code>). In this case, you must explicitly qualify the calls to <code>torch::autograd</code> functions.</p>
|
||
</li>
|
||
<li>
|
||
<p>Because <code>Variable</code> and <code>Tensor</code> are now the same type, code which assumes that they are different types (e.g., for the purposes of templating, or <code>std::enable_if</code> checks) will not work until you delete the (now) redundant overload/specialization.</p>
|
||
</li>
|
||
<li>
|
||
<p>Some operators may trace differently. If this happens, please <a href="https://github.com/pytorch/pytorch/issues/new?template=bug-report.md">file a bug.</a> The most likely situations are:</p>
|
||
</li>
|
||
</ol>
|
||
<ol>
|
||
<li>There are now <em>more</em> operations in your trace than before (usually, calls to <code>aten::empty</code>)</li>
|
||
<li>There are now <em>less</em> operations in your trace than before (e.g., the trace complains that <code>"there is no observable dependence"</code> with the inputs)</li>

<ul>
|
||
<li>Shape checking fixes
|
||
<ul>
|
||
<li>Example 1: previously, <code>torch::tensor({{1}, {2}})</code> produced a tensor of sizes <code>{2}</code>. Now, it produces a tensor of sizes <code>{2, 1}</code>.</li>
|
||
<li>Example 2: previously, <code>torch::tensor(1.1)</code> produced a 1-dim tensor. Now it produces a 0-dim tensor.</li>
|
||
</ul>
|
||
</li>
|
||
<li>Type inference improvements
|
||
<ul>
|
||
<li>Example 1: previously, C++ <code>torch::tensor</code> with a double (e.g. <code>torch::tensor(1.1)</code>) or a (nested) braced-init-list of doubles (e.g. <code>torch::tensor({{1.1, 2.2}})</code> produces a tensor with dtype <code>torch::kDouble</code>. Now it produces a tensor with dtype <code>torch::get_default_dtype()</code>.</li>
|
||
<li>Example 2: previously, C++ <code>torch::tensor</code> with an integer type (e.g. <code>torch::tensor(1)</code>) or a (nested) braced-init-list of integer types (e.g. <code>torch::tensor({{1, 2}})</code>) produces a tensor with the same dtype. Now it always produces a tensor of dtype <code>torch::kLong</code> (aka. <code>int64_t</code>).</li>
|
||
<li>Example 3: previously, when passed a <code>TensorOptions</code> without a dtype set to the <code>torch::tensor</code> constructor, it always produces a tensor of dtype <code>torch::get_default_dtype()</code>. Now it produces a tensor of different dtypes based on the dtype of the braced-init-list and the default dtype.</li>
|
||
</ul>
|
||
</li>
|
||
<li>Passing a <code>std::initializer_list</code> (NOT braced-init-list) to <code>torch::tensor</code> will no longer compile, and the user should pass the equivalent braced-init-list to <code>torch::tensor</code> instead. For example, write <code>torch::tensor({1.1, 1.2})</code> instead of <code>torch::tensor(std::initializer_list<double>({1.1, 1.2}))</code>.</li>
|
||
</ul>

<h3>[C++] Some activation modules’ <code>forward</code> function now take <code>Tensor</code> instead of <code>Tensor&</code> as input.

<p><code>torch::nn</code> layers affected: <code>ELU</code> / <code>SELU</code> / <code>Hardtanh</code> / <code>LeakyReLU</code> / <code>ReLU</code> / <code>ReLU6</code> / <code>RReLU</code> / <code>CELU</code><br>
|
||
This change ensures that the above layers can be used in a <code>torch::nn::Sequential</code> module. If your C++ model uses any of the above layers, you must recompile your C++ code with the new libtorch binary.</p>

<h2>torch.optim</h2>

<p>Learning rate schedulers (<code>torch.optim.lr_scheduler</code>) now support “chaining.” This means that two schedulers can be defined and stepped one after the other to compound their effect, see example below. Previously, the schedulers would overwrite each other.</p>

<h2>ONNX</h2>
|
||
<p>In PyTorch 1.4, we have mainly focused on expanding the coverage for ONNX Opset 11, and enabling exporting torchvision models. Most of the torchvision models can be exported to ONNX (Opset 11, with fixed input size), including FasterRCNN, MaskRCNN, and KeypointRCNN. We have also enhanced export support for some tensor indexing scenarios, with more enhancements to come in the next release. In addition, 20+ new PyTorch operators are enabled in ONNX exporter.</p>

<h1>Deprecations</h1>
|

<h3><strong>Python 2 support is deprecated and will not be supported in the 1.5 release.</strong></h3>
|
||
<h3><code>torch.optim</code>: <code>Scheduler.step(epoch)</code> is now deprecated; use <code>Scheduler.step()</code> instead. (<a href="https://github.com/pytorch/pytorch/pull/26423" data-hovercard-type="pull_request" data-hovercard-url="/pytorch/pytorch/pull/26423/hovercard">26432</a>)</h3>

>>> optimizer.step()
|
||
>>> scheduler.step(epoch)
|
||
DeprecationWarning: The epoch parameter in `scheduler.step()` was not necessary and is being deprecated where possible. Please use `scheduler.step()` to step the scheduler. During the deprecation, if epoch is different from None, the closed form is used instead of the new chainable form, where available. Please open an issue if you are unable to replicate your use case: https://github.com/pytorch/pytorch/issues/new/choose.
