dla-34¶

Use Case and High-Level Description¶

The dla-34 model is one of the DLA models designed to perform image classification. This model was pre-trained in PyTorch*. All DLA (Deep Layer Aggregation) classification models have been pre-trained on the ImageNet dataset. For details about this family of models, check out the Code for the CVPR Paper “Deep Layer Aggregation”.
