Witryna28 kwi 2024 · Just last week I was training a PyTorch model on some tabular data, and wondering it was taking so long to train. I couldn’t see any obvious bottlenecks, but for some reason, the GPU usage was much lower than expected. When I dug into it with some profiling I found the culprit… the DataLoader. What is a DataLoader? Witryna1 lip 2024 · DataLoader. We can now create data loaders to help us load the data in batches. Large datasets require loading them into memory all at once. This leads to memory outage and slowing down of programs.
WitrynaWhen loading a model on a GPU that was trained and saved on CPU, set the map_location argument in the torch.load () function to cuda:device_id. This loads the … Witryna11 kwi 2024 · PyTorch's DataLoader actually has official support for an iterable dataset, but it just has to be an instance of a subclass of torch.utils.data.IterableDataset:. An iterable-style dataset is an instance of a subclass of IterableDataset that implements the __iter__() protocol, and represents an iterable over data samples. So your code would …

Increase num_workers on the dataloader to … Witryna20 lut 2024 · As you can see, the CPU tensor is loaded to GPU memory and then processed by the model in sequence. This pipeline processed 20 batches during the first second. Data Prefetcher. It is possible to further parallelize this pipeline. The data for the next batch can be loaded to GPU while the model is working on the current batch.
