In order to train and evaluate, we need to take the data (the combined one tabular and text) into a folder of tensor files that will be uploaded to the neural network using Pytorch’sDataLoader. We present several code pieces that generate this folder. We begin with the these two function...
In the following cell we iterate over the frames to get a scatter plot of the AV locations: frames = zarr_dataset.frames coords = np.zeros((len(frames), 2)) for idx_coord, idx_data in enumerate(tqdm(range(len(frames)), desc="getting centroid to plot trajectory")): frame = zarr_...
DataLoader 作用:它将大的Dataset转换为小的Python可迭代对象chunk,这些chunk被称为batches,可以通过batch_size设置。它的计算效率更高。 位置→from torch.utils.data import DataLoader 参数→DataLoader(dataset, batch_size, shuffle) 推荐的batch_size→32,通常使用2的幂(32、64、128、256、512) ...
