Then confirm the import works and that <em>torch.cuda.is_available()<\/em> returns True on a GPU machine.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/10\/article-1792731666970.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>Step 2 \u2014 Learn Tensors<\/h2>\n<p>Tensors are the core data structure \u2014 like NumPy arrays, but they can run on a GPU and track gradients.<\/p>\n<ul>\n<li>Create them with torch.tensor, torch.zeros, or torch.rand.<\/li>\n<li>Reshape using .view() or .reshape().<\/li>\n<li>Move to a device with .to(&#8220;cuda&#8221;).<\/li>\n<li>Set requires_grad=True on values you want to differentiate.<\/li>\n<\/ul>\n<h2>Step 3 \u2014 Build a Model<\/h2>\n<p>Subclass <em>nn.Module<\/em>, define your layers in <em>__init__<\/em>, and describe the data flow in <em>forward()<\/em>. Autograd handles the backward pass for you, so you only write the logic once.<\/p>\n<h2>Step 4 \u2014 Write the Training Loop<\/h2>\n<p>The loop is always the same: forward pass, compute loss, call <em>loss.backward()<\/em>, run <em>optimizer.step()<\/em>, then <em>optimizer.zero_grad()<\/em>. Wrap your data in a DataLoader to handle batching and shuffling automatically.<\/p>\n<h2>Conclusion<\/h2>\n<p>Start small: install PyTorch, practise tensors, wrap a model in nn.Module, then run one training loop. That pattern covers the vast majority of real projects \u2014 everything else is refinement.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to Use PyTorch: A Practical Tutorial for Beginners PyTorch is an open-source deep learning library whose dynamic computation graphs make it feel like ordinary Python.
