Web14.14.4. Fine-Tuning a Pretrained Model¶. Again, the dataset for this competition is a subset of the ImageNet dataset. Therefore, we can use the approach discussed in Section 14.2 to select a model pretrained on the full ImageNet dataset and use it to extract image features to be fed into a custom small-scale output network. High-level APIs of deep learning … WebJul 12, 2024 · edited by pytorch-probot bot total no. of params in the model passed into the reducer goes from 4 to 5 We expect to mark 3 params as unused, but only mark 2 the size of the internal func_ (i.e. the number of distinct grad accumulators) stays at 4, instead of 5 (which is what would happen if they have the same no. of parameters). WebFeb 19, 2024 · Simply speaking, gradient accumulation means that we will use a small batch size but save the gradients and update network weights once every couple of batches. Automated solutions for this exist in higher-level frameworks such as fast.ai or lightning, but those who love using PyTorch might find this tutorial useful. 2. example of speaker credibility
