WebFeb 22, 2024 · You can try to use this to save the model with changed problematic operators, transform it in onnx, and fine tune in such form (or even in pytorch). This generally seems best solved by the onnx team, so long term solution might be to post a request for that specific operator on the github issues page (but probably slow).

WebJan 25, 2024 · How to solve it? It is simple: BatchNorm has two "modes of operation": one is for training where it estimates the current batch's mean and variance (this is why you must have batch_size>1 for training). The other "mode" is for evaluation: it uses accumulated mean and variance to normalize new inputs without re-estimating the mean and variance.
