@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 –

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 ...

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

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.

14.08.2019 · 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. However, the maximum number of num_workers is also dependent on available cpu resources, so we might not always be able to achieve that ideal number of num_workers .

After training a ShuffleNetV2 based model on Linux, I got CPU inference speeds of less than 20ms per frame in PyTorch.

09.04.2019 · The Pytorch version is 1.0.1. The parameters in net look like the following: The code of saving parameters looks like: torch.save(net.state_dict(), path) The code of inference looks like: net.load_state_dict(torch.load(path, map_location=‘cpu’)) Is my speed of inference on the CPU normal? How can speed up the inference.

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.)

07.04.2017 · I’ve migrated to PyTorch from Chainer for the library of deep learning, and found PyTorch is a little slower than Chainer at test time with convolutional networks. I’ve noticed this when implementing convolutional networks for segmentation: % ./speedtest.py ==> Running on GPU: 0 to evaluate 1000 times ==> Testing FCN32s with Chainer Elapsed time: 52.03 [s / 1000 …

Apr 08, 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.
