The follwoing tests are failing:

• Anomaly_train: Epoch 0 failed: Anomaly_train: Outputs differ
• KWS_train: Epoch 0 failed: KWS_train: Outputs differ
• LeNet_eval: No handling of MaxPool optional output
• LeNet_train: Backward of BatchNorm is not implemented
• MobileNet_eval + MobileNet_train: Fail to load AveragePool from onnx (no native coverage)
• Perceptron_train: This test has been commented, it works on my machine (and the test server) but ause a segfault in the CI ...
• ResNet_eval + ResNet_train: Fail to load AveragePool from onnx (no native coverage).
