Solve the following python programming problem given the following code:
# Create a linear model

class one_param(nn.Module):
    
    # Constructor
    def __init__(self, input_size, output_size):
        super(one_param, self).__init__()
        self.linear = nn.Linear(input_size, output_size, bias = False)
        
    # Prediction
    def forward(self, x):
        yhat = self.linear(x)
        return yhat
Given the above code, generate some markdown instructions for it.

#Here is the Python program you requested.

This is a custom module. It will behave like a single parameter value. We do it this way so we can use PyTorch's build-in optimizers .
