PyTorch < 2.7 may give wrong results with FractionalMaxPool2d when using torch.compile
published 4 months ago
Summary
If you run PyTorch versions older than 2.7 and use the torch.compile feature, the FractionalMaxPool2d operation can produce unpredictable outputs. This can affect the accuracy of models that rely on this pooling layer. Upgrade PyTorch to version 2.7 or later, or avoid using torch.compile with that layer, to ensure consistent results.
