No, the batch size should not have any effect on BatchNorm layers during eval () besides expected small errors potentially due to the limited floating point precision caused by a different order of operations. Your model also … Webtorch_geometric.loader. A data loader which merges data objects from a torch_geometric.data.Dataset to a mini-batch. A data loader that performs mini-batch sampling from node information, using a generic BaseSampler implementation that defines a sample_from_nodes () function and is supported on the provided input data object.
