Recently, they have gone a league ahead by releasing a pre-release preview version 1.0. + +For those who are not familiar, [PyTorch][1] is a Python-based library for Scientific Computing. + +PyTorch harnesses the [superior computational power of Graphical Processing Units (GPUs)][2] for carrying out complex [Tensor][3] computations and implementing [deep neural networks][4]. So, it is used widely across the world by numerous researchers and developers. + +This new ready-to-use [Preview Release][5] was announced at the [PyTorch Developer Conference][6] at [The Midway][7], San Francisco, CA on Tuesday, October 2, 2018. + +### Highlights of PyTorch 1.0 Release Candidate + +![PyTorhc is Python based open source AI framework from Facebook][8] + +Some of the main new features in the release candidate are: + +#### 1\. JIT + +JIT is a set of compiler tools to bring research close to production. It includes a Python-based language called Torch Script and also ways to make existing code compatible with itself. + +#### 2\. New torch.distributed library: “C10D” + +“C10D” enables asynchronous operation on different backends with performance improvements on slower networks and more. + +#### 3\. C++ frontend (experimental) + +Though it has been specifically mentioned as an unstable API (expected in a pre-release), this is a pure C++ interface to the PyTorch backend that follows the API and architecture of the established Python frontend to enable research in high performance, low latency and C++ applications installed directly on hardware. + +To know more, you can take a look at the complete [update notes][9] on GitHub. + +The first stable version PyTorch 1.0 will be released in summer. + +### Installing PyTorch on Linux + +To install PyTorch v1.0rc0, the developers recommend using [conda][10] while there also other ways to do that as shown on their [local installation page][11] where they have documented everything necessary in detail. + +#### Prerequisites + + * Linux + * Pip + * Python + * [CUDA][12] (For Nvidia GPU owners) + + + +As we recently showed you [how to install and use Pip][13], let’s get to know how we can install PyTorch with it. + +Note that PyTorch has GPU and CPU-only variants. You should install the one that suits your hardware. + +#### Installing old and stable version of PyTorch + +If you want the stable release (version 0.4) for your GPU, use: + +``` +pip install torch torchvision + +``` + +Use these two commands in succession for a CPU-only stable release: + +``` +pip install http://download.pytorch.org/whl/cpu/torch-0.4.1-cp27-cp27mu-linux_x86_64.whl +pip install torchvision + +``` + +#### Installing PyTorch 1.0 Release Candidate + +You install PyTorch 1.0 RC GPU version with this command: + +``` +pip install torch_nightly -f https://download.pytorch.org/whl/nightly/cu92/torch_nightly.html + +``` + +If you do not have a GPU and would prefer a CPU-only version, use: + +``` +pip install torch_nightly -f https://download.pytorch.org/whl/nightly/cpu/torch_nightly.html + +``` + +#### Verifying your PyTorch installation + +Startup the python console on a terminal with the following simple command: + +``` +python + +``` + +Now enter the following sample code line by line to verify your installation: + +``` +from __future__ import print_function +import torch +x = torch.rand(5, 3) +print(x) + +``` + +You should get an output like: + +``` +tensor([[0.3380, 0.3845, 0.3217], + [0.8337, 0.9050, 0.2650], + [0.2979, 0.7141, 0.9069], + [0.1449, 0.1132, 0.1375], + [0.4675, 0.3947, 0.1426]]) + +``` + +To check whether you can use PyTorch’s GPU capabilities, use the following sample code: + +``` +import torch +torch.cuda.is_available() + +``` + +The resulting output should be: + +``` +True + +``` + +Support for AMD GPUs for PyTorch is still under development, so complete test coverage is not yet provided as reported [here][14], suggesting this [resource][15] in case you have an AMD GPU. + +Lets now look into some research projects that extensively use PyTorch: + +### Ongoing Research Projects based on PyTorch + + * [Detectron][16]: Facebook AI Research’s software system to intelligently detect and classify objects. It is based on Caffe2. Earlier this year, Caffe2 and PyTorch [joined forces][17] to create a Research + Production enabled PyTorch 1.0 we talk about. + * [Unsupervised Sentiment Discovery][18]: Such methods are extensively used with social media algorithms. + * [vid2vid][19]: Photorealistic video-to-video translation + * [DeepRecommender][20] (We covered how such systems work on our past [Netflix AI article][21]) + + + +Nvidia, leading GPU manufacturer covered more on this with their own [update][22] on this recent development where you can also read about ongoing collaborative research endeavours. + +### How should we react to such PyTorch capabilities? + +To think Facebook applies such amazingly innovative projects and more in its social media algorithms, should we appreciate all this or get alarmed? This is almost [Skynet][23]! This newly improved production-ready pre-release of PyTorch will certainly push things further ahead!
