[Question] Actual usage examples?

Besides the toy examples listed in the docs and tests, are there actual examples of this library available anywhere?

I’m interested in using this library for a sequence labeling project, but I’m curious to know if I’m using this library correctly. What I have is something like this:

class MyModel(nn.Module):
    def __init__(self, num_features, num_classes):
        super(MyModel, self).__init__()
        self.num_features = num_features
        self.num_classes = num_classes
        self.lstm = nn.LSTM(num_features, 128)
        self.fc = nn.Linear(128, num_classes)
        self.crf = CRF(num_classes)

# ----------------------------------------------------------
model = MyModel(...)

# Training loop:
y_hat = model(batch)  # The network's forward returns fc(lstm(batch))
loss = -model.crf(y_hat, y)
loss.backward()
optimizer.step()

Although this seems to work and the loss is decreasing, I have a feeling that I might be missing something. Any help is appreciated. Thanks!

It may be helpful to provide such loss class for those who are more comfortable with this pattern such as yourself. Thanks for bringing this up.

No problem! That would be an excellent idea. Also thanks for clarification regarding the log_softmax() bit.

Feel free to close this issue, or keep it open as a reminder if you decide to incorporate more examples and also change the library such that loss is separate from the CRF’s output. I’d personally be very happy if the changes/examples are added.
Also, thanks for the great library!

@Huijun-Cui Thanks for letting me know. Next time please open a separate issue.
