I have a neural network with the following structure: class myNetwork(nn.Module): def __init__(self): super(myNetwork, self).__init__() self.bigru = nn.GRU(input_size=2, hidden_size=100, batch_first=True, bidirectional=True) self.fc1 = nn.Linear(200, 32) torch.nn.init.xavier_...

But I am experiencing the below error when I call the function. But the I have similar features in the new_data, which is prediction data as I had in the model fit. I could not resolve this issue. predictions = predictor.predict(prediction_data, n_steps=10) ...
It also makes debugging easier, because a run-time breakpoint or stack trace takes you to the code you actually wrote and not a compiled function in an execution engine. The same variable-length recurrent neural network can be implemented with a simple Python for loop in a dynamic framework....
在这个实现中,我们首先定义了一个FatigueNeuralNetwork类,它继承自nn.Module。我们将输入大小、隐藏层大小和输出大小作为参数传递给构造函数,并定义了一个输入层、多个隐藏层和一个输出层。我们还定义了一个forward方法,用于执行前向传播操作。 在构造函数中,我们首先创建了一个输入层,然后创建了多个隐藏层,每个隐藏层...
