Comparison of PyTorch's Dataset and TorchData API
Deep neural networks take a long time to train. Training speed is affected by factors such as model complexity, batch size, GPU, size of training dataset, etc.In PyTorch, torch.utils.data.Dataset and torch.utils.data.DataLoader are commonly used to load datasets and generate batches. But starting with version 1.11, PyTorch introduces the TorchD ...

libtorch study notes - MNIST combat
MNIST libtorch practical exercise
Ready to work
First download the MNIST database, http://yann.lecun.com/exdb/mnist/
After downloading, do not decompress it with software such as winrar. For example, t10k-images-idx3-ubyte is decompressed into t10k-images.idx3-ubyte. It is best to decompress it with tar in Linux environment.
Suppose you unzip t ...

Using Docker to run HuggingFace massive model
This article will share how to quickly run the interesting model on Hugging Face locally through Docker. Run the model with less code and less time cost than the original project.
If you are familiar with Python, most model projects can be deployed and run locally in about 10 minutes.
Write in front
In order to facilitate the display, I chos ...
