unexpected keyword argument 'rng' in graph.py

[nkundiushuti]

I have seen that you've replaced nrng with rng. is it possible that it should have been replaced somewhere else in the framework?
I get this error in the create_dataset method of the graph.py because my dataset is a class which returns a callable.

When you call train or itertrain, are you passing nrng=... as a keyword argument? If so, just replace that with rng=....

[nkundiushuti]

I am not using this keyword argument. Maybe it's a climate error. As a temporary solution I commented the rng in the graph.py.

this is the code:

e = theanets.recurrent.Regressor(
        layers=(train.input_size, int(1.2*train.input_size), sepNets.lstm_layer(int(1.5*train.input_size)), int(1.8*train.input_size), train.output_size), 
        loss = 'SSEP', step = train.input_size, dist = 0,
        alpha=alpha,gamma=gamma,epsilon=epsilon,tau=tau,
    )

    e.train(
        train, 
        valid,
        algo='rmsprop',
        learning_rate=0.0001,
        momentum=0.9,
        max_gradient_clip=1,
        batch_size=batch_size,
        save_progress=pklnet, save_every=5,
    )

Can you copy the full traceback that you're getting?

[nkundiushuti]

sure..basically I did a more complex version of LargeDataset class you suggested. it was working perfectly before updating to the latest master

I wasn't on the latest version of downhill. this was the problem

[lmjohns3]

Yes, I just got to the same conclusion. :)
