Nov 20, 2019 · Hi guys, I’m new to deep learning. I have a classification task and do the transfer learning using Resnet34(the implementation by PyTorch). The dataset I used is Stanford Car Dataset. For training, I used pretrained weights and fine-tuned the model using the vehicle dataset. The accuracy I got on train dataset and validation dataset is 99% and 89%, respectively (Btw, is there any over ...

torch.jit.optimize_for_inference¶ torch.jit. optimize_for_inference (mod, other_methods = None) [source] ¶ Performs a set of optimization passes to optimize a model for the purposes of inference. If the model is not already frozen, optimize_for_inference will invoke torch.jit.freeze automatically.. In addition to generic optimizations that should speed up your model regardless …

Most real-world applications require blazingly fast inference time, ... The PyTorch code snippet below shows how to measure time correctly.

Aug 14, 2019 · Ideally, a suitable value for num_workers is the minimum value which will give batch loading time <= inference time. This way, when our model is working on inference of previous batch, data-loader would be able to finish reading the next batch in the mean time.

08.04.2020 · MrCrazyCrab commented on Apr 8, 2020 the inference speed of onnx model is slower than the pytorch model. i transformed of my pytorch model to onnx, but when i run the test code, i found that the inference speed of onnx model is about 20fps while the pytorch model can reach about 50fps.

Torch-TensorRT is a PyTorch integration for TensorRT inference optimizations ... With just one line of code, it speeds up performance up to 6x.

To get a sense of the performance benefits of TVM, I compiled a simple PyTorch Mobilenet model trained on CIFAR10 and tested its inference time ...

Performance Tuning Guide is a set of optimizations and best practices which can accelerate training and inference of deep learning models in PyTorch. Presented techniques often can be implemented by changing only a few lines of code and can be applied to a wide range of deep learning models across all domains.

I think using TRTorch[1] can be quick way to generate both easy to use and fast inference models from PyTorch. It compiles your model, using TensorRT, ...

There are a few complementary ways to achieve this in practice: use relatively wide models (where the non-batched dimensions are large), use ...

Performance Tuning Guide is a set of optimizations and best practices which can accelerate training and inference of deep learning models in PyTorch.

@AkshayRana I applied PyTorch Lighning's ModelPruning on a project of mine, and found the inference speed is identical (within 1 standard deviation) for models with 0, 35, and 50 percent sparsity. I've read that speed improvements from pruning should only be expected if you're able to zero-out entire rows/columns of matrices –

20.11.2019 · When I do the inference, I feed one image(224x224) to my fine-tuned model and got correct label. But the inference speed is quite slow: around 160 ms. I think the speed should be much faster than this. So what is a normal inference speed for Resnet34? And how to increase the inference speed? (I know half precision may help, but not really sure.)
